What people love about Thailand Tours in May
Beginning the 18 Day Intro trip I was nervous. Having been a solo traveler, being surrounded by 35 other strangers was a daunting thought. However all nerves were pushed aside that first night. Leaders Jack, Adam, and trainee Keeks helped everyone get accustomed to the new environment and people. Throughout the trip there was a perfect balance between free time and organized activities. There were so many things I would not have had the time to do traveling on my own, and I am forever greatful for the amazing opportunities this tour has given me. I have made lifelong friends and memories that words cannot describe. I would highly recommend this to anyone looking for unforgettable memories in a unforgettable place.
Thai Intro 18 Day
- River Kwai & Ancient Thai Kingdoms
River Kwai & Ancient Thai Kingdoms Tour This was a fabulous three day tour covering a variety of scenic, cultural, religious and historical sites which we found interesting, enjoyable and emotional at times. We had an excellent guide, Nai, a friendly and conscientious young man, who had a wealth of knowledge about all the places we visited along with the traditions, food and lifestyle of the Thai people. He gave us the opportunity to actively participate in the visits to the Temples and Summer Palace which deepened our understanding and enjoyment. The ruins of Ayutthaya were imposing and covered a wide area. Erawan National Park and waterfall were very nice although we would have liked more time to climb to the upper levels. One of the highlights of the trip was the visit to the Hellfire Pass Interpretive Centre and Memorial Walkway. The presentation of the horrific sufferings of the Allied POW’s ad Asian conscripts is sensitively done and the walk is very evocative. The train journey along the tracks of the original death railway was actually still an operating service used daily by workers and school children. Nai introduced us to the night markets in Kanchanaburi and supported our choices whilst eating with the locals. Walking over the River Kwai Bridge and taking a rickshaw to the Allied War Cemetery was a unique experience. The Cemetery and Museum reinforced the sad history of this place. We would highly recommend this very memorable tour which we know was enhanced by having such a great tour guide and accommodating driver, Mr. Bob.

What our customers ask about Thailand Tours in May 2026
What are the best islands to visit in Thailand during May?
The eastern Gulf islands provide the most reliable weather conditions during May. Koh Samui Koh Phangan and Koh Tao see less rainfall than their Andaman coast counterparts making them prime destinations. These islands offer clear waters with good visibility for swimming and snorkeling especially at spots like Bottle Beach in Koh Phangan. Accommodations such as the Fern Resort in Mae Hong Son tend to offer competitive rates during this quieter shoulder season period.
Are there any special festivals or events in Thailand during May?
May brings two significant cultural celebrations to Thailand. Visakha Bucha Day honors Buddha's birth enlightenment and death with temple ceremonies across the country. The Royal Plowing Ceremony takes place in Bangkok's Sanam Luang where ancient Brahmin rituals mark the start of rice growing season. Both events give visitors a genuine look into Thai cultural traditions.
How crowded are tourist attractions in Thailand during May?
May falls within Thailand's shoulder season bringing noticeably smaller crowds to major attractions. Visitors can explore landmarks like Bangkok's Grand Palace and Chiang Mai's temples without the peak-season masses. The Century Park Hotel Bangkok and similar properties often have good availability. Recent visitors report being able to explore sites like Wat Rong Khun at a relaxed pace without the usual tourist congestion.
What are the best activities to do in Thailand during May?
The month presents good opportunities for cultural exploration and indoor activities. Early morning visits to temples like Wat Phra Singh work well before the day heats up. Floating markets draw fewer tourists and the Elephant Nature Park in Chiang Mai remains popular. The Sukosol Hotel Bangkok serves as a convenient base for these activities. Afternoon rain showers provide natural breaks for traditional Thai massages or exploring local markets.
What are the best regions to visit in Thailand during May?
Northern Thailand stands out as a prime destination during May. The cities of Chiang Mai and Chiang Rai offer pleasant temperatures and rich cultural experiences. Bangkok's extensive indoor attractions provide options during rain while the eastern Gulf coast sees less rainfall than western shores. Hotels like the Empress Chiang Mai offer strategic locations for exploring the region while providing shelter during occasional showers.
What is the weather like in Thailand during May?
May signals the start of Thailand's rainy season characterized by warm temperatures and periodic afternoon downpours. Bangkok sees average temperatures of 34°C (93°F) while coastal regions like Phuket run slightly cooler at 31°C (88°F). The afternoon rains tend to be brief but intense creating a rhythm to daily activities. The moisture keeps the landscape green and helps moderate the temperatures.
