To ensure your stay in Thailand for 3 weeks goes smoothly, the weather is a key factor to consider when deciding the best time to embark on this long journey in such a beautiful country.

Below is a schedule of major annual festivals in Thailand for your reference during your Thailand itinerary 3 weeks:
Start your 3 weeks in Thailand by taking an evening flight to Bangkok, then rest at a hotel near the airport to prepare for your departure the next morning to Kanchanaburi.
On the morning of the 2nd day, you will head out to explore Kanchanaburi, a province located in central Thailand, about 130 km from Bangkok.
During your 3 weeks in Thailand, you will spend 2 days discovering this region, which is famous for its spectacular natural beauty, including vast national parks and nature reserves. You can visit Erawan National Park and swim beneath its famous seven-tiered waterfalls.
Additionally, you’ll have the chance to explore the historical sites of Kanchanaburi to gain a deeper understanding of Thailand’s history during World War II, such as taking a train ride on the Death Railway between Thailand and Myanmar.
Located about 130 km from Kanchanaburi, or nearly a 3-hour drive, Ayutthaya is the next stop on your Thailand itinerary for 3 weeks. As the former capital of the country, Ayutthaya was on the trade route between India and China, becoming a rich cultural crossroads between these three nations.
If you enjoy exploring culture and history, Ayutthaya is a must-visit destination. You can visit numerous famous Buddhist temples, such as Wat Phra Si Sanphet – the largest temple in the city – explore the Bang Pa In Summer Palace, a retreat for the Thai royal family, and take a boat trip along the river to admire panoramic views of this ancient capital.
From Ayutthaya, you can take the night train to reach Chiang Mai, located in the northern part of Thailand. Chiang Mai will captivate you with its peaceful beauty and ancient charm, which is quite different from the hustle and bustle of Bangkok. The locals in Chiang Mai are also known for their kindness and warm hospitality towards tourists.
Located at a higher altitude, Chiang Mai enjoys cooler weather compared to other regions. Additionally, with the Ping River flowing through the city, the scenery is extremely picturesque - an essential stop during a 3-week stay in Thailand.
The 5th destination of your 3 weeks in Thailand, Chiang Rai, is located near Chiang Mai. It's just a 3-hour bus ride away, with multiple schedules available for your convenience. This city is renowned for its unique cultural richness, unmatched anywhere else in Thailand. Its temples stand out with singular colors, such as white and blue temples.
For beach lovers, Phuket island is a must-see destination during a 3 weeks in Thailand trip. You’ll travel from Chiang Rai to Phuket by plane, with a flight time of around 4 hours.
Phuket, known as the paradise island located in southern Thailand, is also the largest island in the country. Spending 6 days on this idyllic island will be an unforgettable experience during your Thailand itinerary 3 weeks.
You can visit the most beautiful beaches of Phuket, enjoy fresh seafood, and take part in exciting marine activities like parasailing, kayaking, jet skiing, snorkeling to admire the corals, and more. Around Phuket, there are also many smaller islands waiting to be explored.
At the end of your 3 weeks in Thailand, you will explore the capital city of Bangkok, which is also where you’ll catch your return flight home.
