What is the best time to visit Thailand
While there isn’t necessarily a bad time for a Thailand holiday, the best time to visit Thailand is between November and April. These months offer warm but comfortable temperatures and a low chance of precipitation.

Day 1-3: Bangkok
There is just something about Thailand, something special. Maybe it’s the sizzling sound of street food being prepared, the heat and constant humidity, the organized chaos or the unmistakable smell of incense. Whatever it is, Thailand is a great place to visit!
And there is no better place to start your Thailand route than in Bangkok. After all, no trip to Thailand would be complete without Bangkok, the busy and bustling capital of Thailand.
Bangkok is definitely a city to visit more than once, there is so much to see and do! It’s a foodies paradise as well, offering something for everyone (from vegan restaurants to smoky BBQ street food).
Yes, Bangkok is busy… But if you know where to look there are some peaceful and quiet places to be found as well. One of these places is Lumpini Park, a great place for an afternoon stroll!
Sri Mariamman Temple
I love how there is a Sri Mariamman Temple in pretty much every big city in Southeast Asia. Obviously there is one in Bangkok as well. A very colorful and beautiful one no less!
Jim Thompson house
A very interesting place to visit is the Jim Thompson house. Jim Thomson was an American businessman who fell in love with Thailand and played a crucial role in reviving the Thai silk industry.
In the Jim Thompson House, you can learn more about his story and the impact he had on the silk industry. Even if you are not into silk the house is still a very worthwhile visit, it’s beautifully constructed and decorated with amazing art.
Red Sky Rooftop Bar
Bangkok has lots of rooftop bars and one of the best is the Red Sky Rooftop Bar, you’ll have a beautiful view over Bangkok.
Arrive before sunset and stay until the last light has faded away and the city has been lit up by thousands of twinkling lights (and flashing billboards).
Chao Phraya River
The best way to get around Bangkok is cruising over the Chao Phraya River and admiring the ever-changing skyline. Read more about Bangkok boat transport here.
Where to stay in Bangkok: Ramada Plaza Menam Riverside
I stayed at the beautiful Ramada Plaza Menam Riverside. Large rooms, swimming pool, and a very extensive breakfast buffet. They offer a free shuttle boat (every 30 minutes) to Sathorn Pier where you can transfer to the Skytrain (BTS at Saphan Taksin).
Price per night: €66/$72

Day 4-5: Chiang Mai
Wat Phra Singh
Chiang Mai is the city of temples… One of these beautiful temples in Thailand is the Wat Phra Singh complex.
A typical creature found on many temples in Asia is Naga, also known as the Water Dragon. They look fearsome, don’t they…
Another particularly beautiful one is Wat Bupparam. I love the layered roofs of these types of temples.
The Flight of the Gibbon
Another great activity in Chiang Mai is the Flight of the Gibbon. Don’t worry if you have never zip lined before. Neither had I and even though I have a bit of a fear of heights, it was a very cool experience!
There are 30 platforms, 18 zip lines and the longest zip line is 800 meters! I loved flying through the green canopy and dense jungle, it was exhilarating!
The staff is very knowledgeable, speaks English and makes sure all safety protocols are being followed. I didn’t feel unsafe once during my zipline experience and would love to do it again!
Where to stay in Chiang Mai: The Park Hotel
I stayed at the Park Hotel, a classy hotel with large and light rooms. There is a swimming pool on the roof and they offer a free shuttle service to the night market (every hour).
Day 6-7: Sukhothai
Sukhothai Historic Park
The ruins of Sukhothai are the only remains of the ancient Kingdom of Sukhothai which was founded in the 13th century. Sukhothai means ‘Dawn of Happiness‘ and for several decades this place was indeed a happy place, the first kingdom of Siam (Thailand).
Sukhothai is a UNESCO Heritage site and there are hundreds of old Buddha statues, crumbling buildings, and dilapidated stupas. I recommend to rent a bicycle to explore the site because Sukhothai Historic Park is quite spread out. Bike rental shops can be found across the entrance.
Where to stay in Sukhothai
I stayed at Le Charme Hotel, a nicely set up accommodation with small bungalows arranged around lovely ponds. Swimming pool and open breakfast area. Very close to the entrance of Sukhothai park.
Day 7-8: Ayutthaya
If you haven’t seen enough temples in Sukhothai, continue temple hopping in Ayutthaya. Ayutthaya was the second kingdom of Thailand (from 1350 to 1767). The numerous temples are in various states of decay, from barely more than a pile of rocks to still fully functional Wats with golden Buddha’s inside.
Wat Yai Chai Mongkhon
At Wat Yai Chai Mongkhon, many statues were wearing new brightly colored robes. I was told this was because Buddhist Lent had just begun and the robes are donated to the temples.
When you are in Ayutthaya you must visit the famous Buddha head in the tree! Even though you probably have seen this picture many times, it will still be impressive to see this strange phenomenon in person. A beautiful blend of culture and nature!
When visiting places like Sukhothai and Ayutthaya, I always find it astonishing how people were able to build these impressive structures without any modern equipment.
Wat Phra Si Sanphet
Probably the most famous complex in Ayutthaya and it’s easy to see why. These three tall stupas are a must-see, take plenty of time to walk around and try to imagine what life must have been like back in the days…
Wat Phra Mongkhon Bophit
This is beautiful Wat Phra Mongkhon Bophit, a pretty sight against the green trees and white blue sky.
Where to stay in Ayutthaya
Classic Kameo is a very modern and beautiful hotel! It’s not very centrally located but I found it to be excellent value for money. Fitness area, beautiful swimming pool and lovely rooms with a modern bathroom and super comfortable bed. The breakfast buffet was extensive and the staff very welcoming.
Day 9-10: Kanchanaburi
The bridge over the River Kwai
One of the most impressive places to visit in Thailand is Kanchanaburi. During WWII the Japanese occupied the area and forced thousands of people to work on the railway between Thailand and Burma (now Myanmar).
The railway is also called the Death Railway, more than 100.000 people lost their lives while working on this railroad in horrifying conditions…
Be sure to visit the Jeath War Museum and the Don Rak War Cemetery to learn more about the tragic history of this area. While places like these are difficult to visit, nevertheless, I think it’s crucial to do so. Hopefully, we will learn from the mistakes we made in the past.
Erawan National Park
Kanchanaburi is a very green region and after temple hopping around Sukhothai and Ayutthaya this the perfect place to relax and get back to nature. At just an hour drive from Kanchanaburi you can find the glorious mountains of Erawan National Park!
Besides beautiful mountain views there are also amazing waterfalls in Erawan. You can climb all the way to the top level if you like (there are 7 levels in total). My favorite levels were 4 and 5.
Where to stay in Kanchanaburi
This newly built 3-star hotel is located in the center of Kanchanaburi and within easy walking distance from the main sights in Kanchanaburi. Rooms are decorated in an industrial style with concrete blocks, exposed pipes, and wooden furniture. The spacious rooms have airconditioning, a small fridge and are cleaned daily.
Day 10-12: Koh Samet
Koh Samet, on the other hand, was a pleasant surprise, I found it much less crowded than Koh Tao and really enjoyed the laid-back vibe. Granted, there were fewer diving opportunities but the amazing sunsets and views more than made up for it…
Ao Prao Beach
Hat Sai Kaew
You can explore the island on foot (be sure to bring plenty of water and wear lots of sunscreen), there isn’t much traffic and only a couple of roads. Walking around the entire island will be quite far though, you can also rent a scooter or songthaew to get around.
In the main town Hat Sai Kaew there is some nice art and architecture like the Mermaid sculpture and the main pier.

Where to stay on Koh Samet
Ao Prao Resort is an amazing resort! It’s not cheap but look at the view from the swimming pool! The rooms are beautifully decorated and I had an ocean view from my balcony.
Comfortable bed and modern bathroom. Extensive breakfast served in a beautiful dining area overlooking the ocean. The perfect place to relax after an action-packed itinerary around Thailand…
