Start packing your bags and get ready to explore the best places to visit in the Land of Smiles. 

How many days in Thailand?

Determining the ideal duration for your Thai adventure depends on your preferences, your time available and the level of relaxation you want to achieve. For an immersive journey, a 3-week Thailand itinerary offers a well-rounded exploration of Thailand’s diverse landscapes and cultural gems. This timeframe allows you to experience a mix of activities and destinations, such as the metropolis of Bangkok and the culture in Chiang Mai. Further combined with natural beauty in Pai and Khao Sok and unwind in Koh Samui and Koh Tao, while travelling at a relaxed pace.

If time is more limited, a 2-week itinerary can be tailored to focus on specific regions, such as exploring the cultural north and indulging in island retreats. In that case, I would advise combining one island with a quick visit to Bangkok and the North of Thailand. However, in my opinion, Khao Sok is the best place to visit in Thailand, which might be difficult to squeeze in.

On the other hand, for those with an extended vacation, a 4-week itinerary provides the opportunity to add more destinations to your travel route. In that case, you can visit the islands on both sides of Thailand (add for example Koh Phi Phi and Koh Lanta). Alternatively, you can add cultural destinations. Lastly, you can slow down and stay at the different beaches or in Pai for a longer period. 

Best time to travel to Thailand

While Thailand’s high season and dry period typically span from November to February. This timeframe provides pleasant weather and ideal conditions for most regions, the best time to visit varies depending on the chosen destinations.

What I didn’t know before my visit to Thailand was that not all regions are best to visit between November and February. While the best time to visit Chiang Mai and Pai is between December and March, the southern islands like Koh Samui and Koh Tao are best to visit between January/February and April. If you plan to visit Khao Sok, the drier months from December to April are recommended. For the best overall experience, I would advise you to travel to Thailand between mid-December and March.

Just to let you know, the monsoon season, occurring from May to October, may bring heavy rains, particularly in the southern regions.

|| Explore the capital of Thailand: Bangkok

3 nights

During my last Thailand trip, I decided to skip Bangkok. However, you can’t miss out on Bangkok when you are a first-timer in Thailand. First of all, when in Bangkok you shouldn’t miss out on the famous temples Wat Pho and Wat Arun. Also, the Royal Palace is home to rich culture and abundant golden temples. Furthermore, a great way to explore Bangkok is with a biking tour by Ko van Kessel. Of course, if you want to experience backpacker madness in Thailand, you can’t miss out on the famous Koh San Road. Also, visit one of the famous rooftop bars to admire Bangkok from above. Lastly,  a floating market, such as Amphawa, is a great addition to your visit to Bangkok.

|| Head to Northern Thailand: Chiang Mai

3 nights

From Bangkok, you can either fly to Chiang Mai or take a night train. If you are keen on taking the night train, make sure to book your tickets early on. Chiang Mai is the largest city in the North of Thailand and offers a great combination of nature and culture. Top things to do are for example to explore the Old Town or visit one of the night markets or the Night Bazaar. Also, you should enjoy a cup of coffee or a cocktail in the popular Nimman neighbourhood. Next to that, you can’t miss out on the famous temples within Chiang Mai, such as Doi Suthep, Wat Pra Sing and Wat Chedi Luang. However, my personal favourite was Wat Pha Lat, which can be reached by hiking the famous Monk’s trail. 

Also, there are spectacular day trips available from Chiang Mai, such as a visit to the Sticky Waterfalls, Doi Inthanon or Chiang RaiLastly, Chiang Mai is the perfect location to indulge in the local culture. For example, enjoy local food such as Khao Soi, relaxing with a Thai Massage and trying a Muay Thai Class.

|| Laid back vibes and Lush nature in Pai

4 Nights

Pai was one of my favourite places in Thailand, and I know for a fact I’m not alone in that opinion. This beautiful laid-back town in the north of Thailand offers a wide range of activities, a set of great restaurants and bars. Due to the great vibe, I recommend staying in Pai for 4 nights, so you have enough time for a set of day trips. When heading from Chiang Mai to Pai, you can either rent a motorbike and drive yourself or take a shared van (3-hour drive).

Firstly, you can’t miss out on a visit to the Bamboo Bridge, Santichon Village and the Yun Lai Viewpoint. Furthermore, the White Buddha near Pai is an easy attraction to visit. Next to that, you must watch the sunset at the Pai Canyon and/or Two Huts during your stay. Lastly, there are some great activities to further explore Pai’s beautiful nature, such as a visit to the Nam Lod Cave or the Mae Yen Waterfall. 

Moreover, you have to visit Pai’s night market, head for a lovely brunch at Bom Bowls or OM Garden and step your foot into the nightlife at for example Jazz House or Music.Bros Bar.

|| My favourite place in Thailand: Khao Sok

3 nights

After Pai, you’ll have to travel a bit longer to get to your next destination. However, it’s more than worth it! From Pai, head back to Chiang Mai and take a flight to Surat Thani. From the airport, it is a 1.5-hour drive to Khao Sok village. Upon your arrival in Khao Sok, book the overnight lake tour starting the next day. In my opinion, this overnight lake tour in Khao Sok was the most beautiful and impressive experience during my time in Thailand. 


Check out my Khao Sok Travel Guide to learn all about the overnight lake tour and the best restaurants in Khao Sok.

|| Relax on the islands: Koh Samui

3 nights

After Khao Sok, it is time to head to the beautiful Thai islands to end your 3-week Thailand Itinerary with some well-deserved beach time. I choose to travel to the islands in the east of the country, where you can combine Koh Samui, Koh Phangan and Koh Tao. Alternatively, you can choose to visit the western islands such as Koh Phi Phi and Koh Lanta including a visit to Krabi. 

However, I liked the mix of the eastern islands better and this also matched my Muay Thai adventure as there are plenty of Muay Thai schools on Koh Samui. When in Koh Samui, you can visit some lovely temples such as Wat Pai Laem, visit the beautiful beaches on the island and visit the Overlap Stone and Na Muang Waterfall.

|| Escape to paradise: Koh Tao

4 nights

Your final destination during your 3-week Thailand Itinerary is Koh Tao, a smaller idyllic island, perfect for diving. You can reach Koh Tao by boat (1,5 hours) from Koh Samui. When in Koh Tao, you can’t miss out on a short visit to Koh Nang Yuan to visit the viewpoint. Also, there are plenty of hidden and local beaches on Koh Tao, that you’ll pass when hiking the coastline. Lastly, you can’t miss out on visiting John Suwan Viewpoint. 

Furthermore, when staying near Sairee Beach there are plenty of remarkable food options, such as Cactus Cafe, 995 Roasted Duck and The Factory Cafe.
