What people love about Thailand Tours in May
- Bangkok to Chiang Mai Express
The tour was great. We had an unexpected 6 hour delay at the train station. Maybe have a back up plan if something like that were to happen again. Enjoyed the tour and the group.
- Thai Intro 18 Day
As this was my first time travelling with my girlfriend I was quite nervous at the thought of everything involved and decided to book an organised tour with intro travel and I could not have made a better choice. From the moment I arrived in Thailand to the final day everything was managed and planned amazingly and allowed me the opportunity to live and experience so many things I wouldn't have known about or done by myself and will never forget! The group of people on my tour were amazing and I think I could speak for everyone in saying that we have made friends for life. I don't think we could of asked for a better tour guide than Josh, he constantly made every day enjoyable and made sure everyone was involved and making the most of every day (even the hungover days). He was also very knowledgable about Thailand as a whole and his ability to speak Thai allowed the group to feel even more immersed in the local culture. His professionalism also deserves a mention from providing advice and guidance on future travelling, to supporting people during some unfortunate events such as loss of passports etc...he truly is an asset to the intro travel team. The itinerary of the tour itself was amazing, from the floating bungalows at Khao Sok National Park, jungle zip lining to the Elephant sanctuary all memories I will never forget! I would definitely recommend Intro Travel to my friends and family and anyone who wants to travel as I had such an unforgettable trip of a lifetime and enjoyed it so much I've already booked onto the Intro travel Vietnam tour in the next few weeks :)
- Thailand Grand Tour, Small Group Tour (English Only)
Whilst the hotels themselves were excellent as far as accommodation and breakfast were concerned (except for the hotel at sukhumthai where eggs were obviously cooked very early in the morning and were cold at 7-00 am .Maybe we were spoilt at other hotels in that a chef was provided to cook eggs as one liked along with omlettes and other asian delicacies on the spot ) Further the hotel at Chaing Ria was in a reasonable location considering we were there for 2 days and no early rises .As such time was available to explore the city. Whilst the Holiday Inn at Chaing Mia was probably the best of all the hotels, its location was terrible in that it was about an hours walk to the night market. The hotel at Sukhumthai was 4 kilometres from the old town and 12 kilometres from the new town.Terrible Having said the above and considering the locations of the hotels it would have been helpful to have the tour guide advise how to get to the bustling townships ie by taxi or tut tut and the cost as your tours do not allow for a brief tour and advice as to the attractions in the various townships .Yes we see allthe temples and other tourist attractions however we do not see much of the local people. Finally on the last two days of the tour we were left to our own devices in chinatown Bangkok. It would have been nice for the tour guide to have given us a brief tour of Bangkok city and explained the best method of transport ie taxi or tut tut and even an explanation of how to use the rail system Brian Nichols
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.
