There is a lot to see and do in Thailand, and in this article, we will show you the main attractions of this charming country.

Bangkok – the capital of Thailand
A visit to Thailand would be incomplete without a stop in Bangkok, a fascinating, lively and colorful city with countless temples, parks, skyscrapers, and welcoming people.
Bangkok is the starting point to the other parts of the country, and if you get here, it would be a shame not to spend a few days in this city of contrasts.
We wrote a guide for visiting Bangkok here (airports, transportation and tourist attractions).
What to do in Bangkok?
Visit the temples
A tour of the temples is the best way to discover the religious traditions and customs of the Thai people. There are many temples in Bangkok, but the most visited by tourists are the following:
The Grand Palace is in the heart of the city and consists of several richly ornate temples. The most important temple in the complex is Wat Phra Kaew, which houses the famous statue of the Emerald Buddha.
Wat Pho – The Temple of the Reclining Buddha is near the Great Palace and it is famous for the 46-meter-long Buddha statue.
Wat Arun – The Temple of Dawn has a unique architecture and it is located on the banks of the Chao Phraya River.
Wat Saket – The Golden Mount is our favorite temple in town. It is located on the golden mount and offers a 360-degree panoramic view of the city.
Admire the city from above
Drinking a colorful cocktail while enjoying a breathtaking view of the city is the finest way to spend your evening in Bangkok.
We went to the Octave Rooftop Bar at the Marriott Sukhumvit Hotel and the view seen from here is fabulous.
Octave Rooftop Bar is open daily between 5 PM and 2 AM and it is 5 minutes away from the Thong Lo Station of the BTS Skytrain.
The most popular bars in the city are Sky Bar, the Dome at Lebua State Tower (it appeared in the movie The Hangover), Octave Rooftop Bar at the Marriott Sukhumvit Hotel, Vertigo and Moon Bar at the Banyan Tree Hotel and the Park Society at the So Sofitel.
Visit the Jim Thompson House Museum
Visit the Jim Thompson Museum and learn interesting things about the silk industry.
Jim Thompson founded the Thai Silk Company in 1948. The company had a huge success in the silk industry and its products are being sold even today.
Jim Thompson mysteriously disappeared in 1960 during a trip to Malaysia and his body was never found.
Hours: 9 AM – 6 PM
Admission: 200 Bath / adult, 100 Bath / child under 10 years.
The museum is near the National Stadium or Siam Stations (BTS Skytrain).
There are many modern malls in Bangkok, and most of them are open between 10 AM and 10 PM.
Terminal 21 is one of the most interesting malls in the city. It is located in Sukhumvit (Asok – Skytrain Station). Each floor is decorated with representative decorations for a particular area of the globe (Istanbul, San Francisco, London, Paris, Rome, Tokyo and the Caribbean).
Buy from the Markets
There are many markets in the city (weekend, night or day markets) from which you can buy products from local producers.
Use public transportation
If you use public transport, which passes through the less touristy areas of Bangkok, you will see a part of the city that remained authentic.
The main means of transport in the city are the subway, the Skytrain and water transport, and these are very well developed and very fast.
Read more about Bangkok’s public transportation here.
There are several floating markets in Thailand, and most of them are near Bangkok.
Most markets are open only on weekends, but as we didn’t stay over the weekend in Bangkok, we visited the Damnoen Saduak Floating Market which is open daily between 7 AM and 5 PM.
We arrived at the floating market with a tour of Bangkok, which included a visit to the Damnoen Saduak Floating Market and Maeklong Train Market (the market through which the train passes).
Erawan National Park – Kanchanaburi
Erawan National Park in Kanchanaburi (about 190 km from Bangkok) is one of the most beautiful places we have visited in Thailand.
The 7-level Erawan Waterfall is the largest attraction in the park. The trail to the last level of the waterfall is quite impressive and the color of the water from the natural pools formed on the route is amazing.
The park is open daily from 8 AM to 4:30 PM and the entrance ticket costs 300 Bath.
Other attractions in Kanchanaburi
- Elephants World is a sanctuary where you can interact in an ethical way with these huge animals (you can feed them, walk with them and take a bath in the river).
- Sai Yok Yai National Park is a place of impressive natural beauty and the park’s star is the Sai Yok Yai Waterfall.
- Chaloem Rattanakosin National Park is another park where you have the chance to hike interesting trails, the biggest attraction in the park is the Tham Than Lod Noi Cave.
- Khuean Srinagarindra National Park is located near Erawan National Park, here are several caves and the Huay Mae Khamin Waterfall.
- The Bridge on the River Kwai (Death Railway Bridge) is also called the death bridge because of the large number of war prisoners who died during the construction of the railway.
- Hellfire Pass Memorial Museum – the 500-meter pass was hand-cut into stone, and the museum is dedicated to people who have lost their lives by working hard here.
- Wat Tham Sua Temple is a temple with unique architecture.
How do you get to Erawan National Park?
We took a day trip from Bangkok.
Another option would be to take the minibus or train from Bangkok to Kanchanaburi and from there, the bus, a private tour or the Songtaew (shared taxi) to the park.
More details are available here.
Ayutthaya is approximately 75 km north of Bangkok
The ruins of the ancient city of Ayutthaya show the former grandeur of the city when it was considered the largest city in the world.
Thailand’s official name has long been Siam, and Ayutthaya was the capital of the Siam empire. The ruins of the temples that can be visited here today are what remained of the city after the invasion of the Burmese army in 1767, an attack that led to the collapse of the empire.
How can you get to Ayutthaya?
By train from Bangkok
Although you can get to Ayutthaya from Bangkok by bus or minibus, the train journey is much more interesting.
The ticket costs only 30 Bath and the train runs once per hour between 4:20 AM and 10 PM.
The train leaves from Bangkok’s Hualamphong station (you can get here by metro) and the journey takes between 1.5 and 2 hours.
How can you travel through Ayutthaya?
Most tourists choose to tour the temples with the tuk-tuk. You can choose which temples you want to see and negotiate the price of the tour, and if you do not have an itinerary, the drivers will recommend you a tour of the main temples.
What to visit in Ayutthaya?
Ayutthaya is situated in the place where 3 rivers (Chao Phraya, Lopburi, and Pa Sak) meet forming an island, most of the temples are on this island (Wat Mahathat, Wat Ratchaburana, Wat Trammikaarat, Wat Phra Sri Sanphet, Wat Phra Ram, Wat Lokayasutharam, and Chao Sam Phraya National Museum).
Ayutthaya Historical Park
Ayutthaya Historical Park consists of the ruins of the most important temples from the old Ayutthaya: Wat Mahathat, Wat Ratchaburana, Wat Phra Sri Sanphet, Wat Mongkhom Bophit and Wat Phra Ram.
A stop in this park is mandatory, and the good news is that the temples in the park are very close to each other, so you can walk within a few minutes from one temple to the other.
Wat Mahathat and Wat Ratchaburana
The two temples are located in the same area, the Wat Ratchaburana temple is well preserved and the Wat Mahathat temple is famous for the Buddha’s head hidden among the tree roots.
It is one of the most interesting temples in the city, consisting of the ruins of the old temple (with many statues depicting lions and roosters) and other new constructions.
This temple is not part of Ayutthaya Historical Park, but it is also located on the island. Here is the largest Buddha statue in the city (8 meters high and 42 meters wide).
In the same area, you can visit for free 2 other interesting temples: Wat Worachettharam and Wat Warapho (Wat Wang Rakhang).
We also visited 2 temples located outside the island: Wat Yai Chai Mongkhol and Wat Phanan Choeng Worawihan.
Wat Yai Chai Mongkhol
It’s our favorite temple in town. The terrace of the temple can be visited and the view from there is very beautiful. The garden surrounded by statues is also exceptional.
Wat Phanan Choeng Worawihan
The temple is in a very beautiful area, on the riverbank.
This temple houses the 19-meter-high golden Buddha statue. There are several buildings in the complex, including a Chinese temple.
Chiang Mai offers a variety of attractions, a combination of history and modernity, but what makes it such a special place is the tranquility of the city and the locals, smiling and welcoming people who will brighten your day and will make you understand why Thailand is called “The Land of Smiles”.
Chiang Mai is a city with large boulevards, which stretches along the river and it is possible to tour the city’s attractions on foot or by bicycle.
In the old town, there are 30 temples and stalls selling food, and in the new town, there are several restaurants and shops.
How can you get to Chiang Mai?
Chiang Mai is the largest city in northern Thailand, and it is the capital of Chiang Mai Province.
The city is 700 km north of Bangkok.
Chiang Mai International Airport (CNX) is the 4th largest airport in the country, after the two airports in Bangkok and the Phuket Airport. Domestic and international flights arrive at this airport.
We flew here from Bangkok and from here to Phuket, both flights were operated by AirAsia.
How do you get from the airport to the city?
The airport is about 10 minutes away by car from the city.
Chiang Mai Airport Bus
It only costs 20 Bath, it is the cheapest option and the bus runs every 20-30 minutes between 6 AM and 10:30 PM.
The 2 routes reach the city and have stops at Nimman Road, Chang Phuak Gate, Three Kings Monument, Tha Phae Gate and Night Bazaar.
By taxi / Grab
The trip costs between 100-200 Bath, depending on the distance.
Since April 2018, Uber is no longer available in Thailand, but if you want to order a taxi using an app, you can use the Grab app.
By Songtaew (shared taxis)
Generally, the trip costs around 40-60 Bath / person.
With the tuk-tuk
The tuk-tuk trip costs around 150 Bath.
The minibus trip costs 60 Bath, but it does not have a fixed schedule and leaves the station only when it is full.
By bus from Bangkok
Several buses are departing daily from the North Terminal of Bangkok to Chiang Mai. The tickets for the express buses can also be purchased online (for example from 12go.asia).
By train from Bangkok
We wanted to take the night train from Bangkok, but unfortunately, there were no free seats on the 1st class.
The second-class seats turn into beds too and they seem quite comfortable, and the third-class has normal seats.
The train starts from Bangkok’s Hua Lamphong Station (you can get here by metro) and arrives at Chiang Mai Train Station, which is just 3 km away from the city center. From the train station, you can reach the city on foot or by taxi, tuk-tuk or Songtaew.
Ticket prices range from $ 30- $ 60 / person and can be purchased online from 12go.asia or directly from the train station with a maximum of 60 days before the trip.
12go.asia calculates all the options you have to travel between 2 places, and it is very useful when you want to choose the most convenient variant between train, bus, plane and minibus. (The pictures of the means of transport and the reviews from other travelers from this website will help you make the best decision.)
Where to stay in Chiang Mai?
We stayed at a small hotel in the old town. In all our travels so far, we haven’t met a family as friendly as the owners of the Little Guest House Hotel.
The hotel is located a few minutes’ walk away from the temples, restaurants and the night market. If we return to Chiang Mai, we will definitely choose the same hotel.
What to visit in Chiang Mai?
Wat Phra That Doi Suthep
The temple is located on Mount Doi Suthep in Doi Suthep-Pui National Park, 15 km from Chiang Mai.
Many legends speak about the reason behind the construction of the temple in this location, but the most popular legend is the one that says that the temple was built to house a Buddha’s shoulder bone, which was brought to the mountain by a white elephant, before putting the bone on the back of the white elephant, it broke into 2 pieces, a piece was enshrined at Wat Suan Dok in Chiang Mai.
The elephant died in this place, and so it was decided to erect the temple here. The legend is somewhat confirmed by the white elephant statue at the temple, which carries a golden chedi in the back.
How you can get here?
You can hike the monks’ trail / Nature Hike or take a taxi or songthaew.
We took a songthaew from the station near Chang Pauk Gate, 2 minutes from the hotel and paid 50 Bath / person.
The journey to the temple took 40 minutes. The car left us in the parking lot at the base of the temple. Near the parking lot, there is a small market where you can buy coffee, juices, fresh fruits, food or souvenirs.
What does the temple look like?
Wat Phra That Doi Suthep is a sacred place for Thai people and probably the most important temple in the region.
The temple is at the end of the stairs whose railing is made up of Naga statues. The complex consists of several temples, buildings and terraces.
The temple is also known for the surprising panorama of Chiang Mai seen from the temple terrace. As we visited the temple early in the morning, we avoided the crowds, but a part of the city was covered in fog and we didn’t enjoy the best view.
Entry tickets: 30 Bath
Hours: 5 AM – 9 PM
Wat Phra That Doi Suthep is the only temple we visited outside the city, the rest of the temples are in the old town and we toured them on foot. Most of the temples in the old town can be visited for free.
Wat Chiang Man
Wat Chiang Man was the first temple built in the city. In the temple, there are 2 images and 2 very old Buddha statues, of great significance for the Thai people.
The walls of the main temple are covered with very colorful paintings, paintings that we have not seen in other temples. Chedi Chang Lom, surrounded by 15 elephants, is the oldest building in the complex.
The complex can be visited daily between 6 AM and 5 PM and admission is free.
Wat Chedi Luang
The temple is open between 8 AM and 5 PM, and we arrived at 7:30 AM at the temple, so we had breakfast at a nearby restaurant.
The complex consists of 3 temples: Wat Chedi Luang, Wat Ho Tham, and Wat Sukmin and can be visited for free.
Part of Wat Chedi Luang was destroyed in the 15th century, during an earthquake. The temple has housed the statue of the Emerald Buddha for nearly 100 years. The statue is now in the Wat Phra Kaew Temple, inside the Grand Palace in Bangkok.
Wat Lok Molee
Although not one of the most famous temples in the city, it is a very beautiful temple. The garden is decorated with different statues and the entrance to the temple is guarded by 2 white elephants.
The temple can be visited for free between 6 AM and 5 PM.
As we walked from one temple to another, we visited several temples on our route.
Chiang Mai Night Bazaar and Sunday Walking Street
There are several markets in Chiang Mai, but the largest and most important are Chiang Mai Night Bazaar and Sunday Walking Street.
The Night Bazaar is open daily between 6 PM and 10:30 PM and it is at the intersection of Chang Khlan Road and Loi Khro Road.
Sunday Walking Street Market is open every Sunday from 4 PM until midnight. The market starts at ThaPae Gate and stretches 1 km along Ratchadamnoen Rd. The street is closed to traffic and it is full of stalls selling everything you could need.
Our hotel was located close to both markets and we were lucky to stay over the weekend in Chiang Mai, so we visited them both.
Long Neck Karen – Baan Tong Luang
We visited 2 such villages in the north of Thailand, one near Chiang Mai (30 minutes by car), and one on the way to Chiang Rai, as they were part of the tours we did.
We liked more the village near Chiang Mai (Baan Tong Luang), it occupies a larger area, it has a school, a church and lots of green space. In the village, there are people from several tribes: Karen, Hmong, Mien / Yao, Lahu, Lisu, and Kayan Long Neck.
The houses are made of bamboo, and in front of the houses, people sell souvenirs. We bought some handmade scarfs because we liked them and because the guide told us that a part of the profits remains in the community.
Mae Sa Waterfall
The 10-level waterfall Mae Sa is situated between Chiang Mai and Baan Tong Luang village. The waterfall is not so beautiful like the Erawan waterfall, but the trail is very interesting, and the vegetation is impressive. In some pools, you can swim, and on the route, there are places where you can take a break and have a picnic.
The trail wasn’t difficult and we walked it smoothly even though we didn’t wear hiking shoes.
The waterfall is part of the Two Suthep-Pui National Park.
The entrance ticket costs 200 Bath.
Chiang Mai Night Safari
We ended the day with a night safari at the Chiang Mai Zoo.
Since we arrived quite late, we went straight to the ticket office and then entered the complex exactly when the Creatures of the Night Show started. It is a dance show, there were several costumed dancers and a fire dancer.
After the show, we went to the train station. Before arriving at the station, it is a stall where you can buy food for the animals. The train passes among the animals, some are closed behind the fence, and others are left free. If you have bought food, you can feed the giraffes or antelopes. The tour takes about 60 minutes.
There were other shows available, but because they were animal shows, we decided not to go.
Tickets for day safari (3 PM – 4:30 PM) and night safari (6:50 PM – 10 PM) cost 800 Bath / adult and 400 Bath / child. More details about the schedule and activities are available on the website.
There is a free shuttle service from the city available, from Imm Hotel (4:45 PM) or Night Bazaar (5 PM) and return at 9 PM.
Chiang Rai is 200 km north of Chiang Mai. You can get here by plane (Mae Fah Luang International Airport), by bus or a tour of Chiang Mai (by minibus or boat).
We took a tour of Chiang Mai and visited the White Temple near Chiang Rai and the Golden Triangle.
Wat Rong Khun – The White Temple
The White Temple was designed and built of its own money by the local artist Chalermchai Kositpipat. The architecture of the temple is unique in the world, it is decorated with lots of statues, each symbolizing something in the creator’s conception.
To enter the temple, you will have to cross a bridge where you will see different statues and a fountain with hundreds of outreaching hands, which symbolizes desire.
You are not allowed to take pictures inside the temple, but you should study the complexity of the paintings on the walls, where, among other things, Superman or Hello Kitty also appear.
All the buildings in the complex have a different architecture, but the project is still in progress and in the end, there will be 9 buildings.
You will need at least one hour to visit the complex. We liked the temple’s unreal architecture, but it might have been better if we visited it earlier, because it was extremely crowded at the time we arrived.
Admission tickets cost 100 Bath and the temple is open daily between 6:30 AM and 6 PM.
The golden triangle is the place where the borders of Thailand, Myanmar and Laos meet.
In the past, this was one of the areas where most opium was produced and the region is also known as Sop Ruak (the place where the Mekong and Ruak rivers meet).
Attractions in the area include a Buddha statue in a boat and a market on the island of Don Sao from Laos that can be visited without a visa.The market is on the other side of the river, and we took a 30-minute cruise on the Mekong River before heading to the market.
In the area, you can also visit Wat Phra That Pu Khao situated on the mountain and the Opium Museum.
Mae Sai is located on the border between Thailand and Myanmar and it is the northernmost point in the country. We stopped for about an hour here and walk through the market.
Phuket and the nearby Tropical Islands
Thailand is famous for the beautiful white tropical beaches and the bays with turquoise water. The islands with stunning landscapes are the main attraction of the country.
Patong Beach in Phuket
We weren’t sure, whether to stay in Phuket or Krabi, but in the end, we realized that it didn’t matter anyway because we planned to spend most of our time on the surrounding islands.
Finally, we stayed at the Bliss Hotel on Patong Beach in Phuket, a few minutes’ walk away from the beach.
Coming from the north of the country, where people were very nice, we had a shock when we arrived in Patong and went for a walk on the famous “Bangla Road”. We were sad to see what kind of things are happening on that street, and honestly, it is hard to understand what kind of people might approve that. This is indeed another type of tourism for which Thailand is unfortunately famous, but in our opinion, Thailand is a beautiful country, with many incredible landscapes and natural attractions that are worth being promoted first.
In Patong, there are many restaurants, a souvenir market, many clubs and a huge beach.
We did not spend much time in Phuket and preferred to make trips to the nearby islands every day.
If you still spend several days in Phuket, we have some recommendations for you:
- Take a tour of the beautiful beaches on the island (we rent a taxi in Thailand for 500 Bath / day).
- Visit the Big Buddha Statue
- Visit Tiger Cave
- Visit the Emerald pool
Which are the islands we liked the most?
Phi Phi Islands
Phi Phi Islands are a group of 6 islands located about 40 km from Phuket and are part of the Tha Nopparat Thara-Ko Phi Phi National Park. The park consists of several islands and the coral reefs around them.
The Phi Phi archipelago has 2 main islands: Koh Phi Phi Don and Koh Phi Phi Leh.
Koh Phi Phi Don is the largest and most visited island in the archipelago and has several accommodation units available.
On Koh Phi Phi Leh island are the Maya and Loh Samah Bays, Pileh Lagoon and Viking Cave. There are no accommodation units on the island, which is why it can only be visited on a day trip.
The beach that appeared in the movie “The Beach” with Leonardo DiCaprio was closed to tourists in June 2018 for an indefinite period for nature to recover. We visited the beach in 2018 and it is gorgeous.
There are lots of tours you can take from Phuket or Krabi to visit the Koh Phi Phi islands. Most tours include stops on the 2 main islands Koh Phi Phi Don (Monkey beach (Yong Kasem)) and Koh Phi Phi Leh (Pileh lagoon, Viking cave) and the Khai islands or Bamboo Island. Our tour cost about $ 80 / person.
How was our day?
Early in the morning, we were taken from the hotel and headed for the Phuket Marina. After a brief training on what we will visit and the safety measures for this tour, we headed to the island of Koh Phi Phi Leh. Normally the tour would include a stop at Maya Bay, but now the bay is closed and can only be admired from a distance.
We made the first stop in the beautiful Pileh Lagoon, the lagoon is protected by high limestone walls covered with green vegetation and the watercolor in the bay is emerald green. Here we had to choose between admiring the natural beauty of the place from the boat or swimming in crystal clear water.
Next, we visited the Viking Cave and Monkey Beach, we did not stop at the beach, but only watched the monkeys from the boat.
We had lunch at a restaurant on the beach in the Ton Sai Bay of Koh Phi Phi Don, after which we had free time to enjoy the beach.
We spent the last part of the day on the Khai Nai Island, a very small island, with a white sandy beach and a small market where you can buy souvenirs, food or drinks. The beach is very beautiful, but on our visit, it was very crowded, given the small size of the island. In the turquoise waters around the island live several species of colored fish and it is a suitable place for snorkeling.
Phang Nga Bay
Phang Nga Bay Marine National Park consists of 42 islands and several coral reefs. The best-known island is James Bond Island, where the film “The Man with the Golden Gun” was shot in 1974.
We took a day trip from Phuket which included visiting James Bond, Panyee and Lawa Islands and kayaking around the Panak and Hong Islands. The tour cost about $ 100 / person.
We really enjoyed the kayak tour. We passed through some caves, among the mangroves and by beautiful landscapes.
James Bond Island (Koh Ta-pu)
You will have the best view of the rock towering in the middle of the bay, from the island of Khao Phing Kan. There are several points on the island where you can see or photograph the island of Koh Ta-pu, a few caves and a small market.
Koh Panyee (Floating Muslim Village)
Koh Panyee is a small island, made up of limestone rocks that rise vertically from the water. Panyee village is built on pillars above the water and includes several restaurants, a school, a mosque, and some souvenir shops. Most day trips stop for lunch in this village.
The image of the village, floating above the water, at the base of the huge limestone is fabulous and we recommend you visit it.
Our tour ended with a stop on Lawa Beach, a small white sand beach. We do not know if this is usual, but at our visit, the water was quite dirty, which is why we did not swim but just lay on the beach.
The archipelago is approximately 84 km from Phuket and consists of 11 islands that can be referred with numbers:
- Island 1: Ko Huyong
- Island 2: Co Payang
- Island 3: Co Payan
- Island 4: Ko Miang
- Island 5: Ko Ha
- Island 6: Ko Payu
- Island 7: Ko Hin Pousar
- Island 8: Co Similar
- Island 9: Ko Ba-ngu
- Island 10: Co Bon
- Island 11: Ko Tachai
The island Ko Tachai (number 11) was closed for an indefinite period for nature to recover. Islands 1,2 and 3 are closed to tourists to protect the turtles laying their eggs on the beach.
Mu Koh Similan National Park is closed during the rainy season every year (May 16 – October 15), and in 2018 it was decided to limit the number of tourists who are allowed to visit the park in one day.
The park can be visited on a day trip from Phuket or Khao Lak or a multi-day diving trip (in which case you will spend the night on the boat because you are not allowed to stay overnight on the islands). The trip by high-speed boat from Phuket to the islands takes about 1.5 – 2 hours.
We took a day trip from Phuket, which cost 2715 Bath / Person (about $ 94).
The attractions of the archipelago:
The park is famous for its beautiful white-sand beaches and the coral reefs, being considered one of the best places in the world for diving. We saw a lot of colored fish and some turtles, but unfortunately, most of the corals were dead.
The first stop we did on the island number 8 Ko Similan. This is the largest island in the archipelago and probably all tours will stop here. The water in the bay is perfect for swimming, the white beach is gorgeous, and we recommend that you hike to Sailing Boat Rock and enjoy an amazing view.
In the second part of the day, we snorkeled in 2 locations and had lunch on island 4 Ko Miang, the second largest island in the archipelago, on the beautiful beach of Honeymoon Bay.
We couldn’t leave Thailand before trying the famous Thai massage. It’s hard to say how it was because the experience was different for each of us. While Mihai came out reinvigorated, I didn’t enjoy the “treatment” that I received, and I don’t want to repeat the experience.
These are our recommendations for those who plan to visit the “Land of Smiles”. We wrote an article with useful information for organizing a trip to Thailand here (visa, means of transport, costs, airports) and the guide to visiting Bangkok is available here.
