What people love about Thailand Tours in December
- Thai Experience
I Attended the Thai Experience tour in December of 2017. The itenerary was great with a good mixture of pre-planned activities and down time. Jack an Adam, our guides, were awesome. They were knowledgable and professional. It genuinely was their mission to ensure everyone had a great time and got what they wanted out of the trip. This isn't just a job to them! I would highly recommend this trip in particular for anyone wanting to see Thailand and company in general to anyone wanting to see any of their destinations either as a group or solo traveller. Cheers for a great time in Thailand!
- 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 :)
- Real Thailand
This trip was incredible. First of all...Katie is the best tour guide ever and the most amazing person! She is the best :) The Essential Thailand tour was great and I would definitely do it again... beautiful temples, scenery and elephants in the north and then stunning islands in the south! It's the perfect trip if you want to see as much of Thailand as possible!

December brings ideal weather conditions to Thailand with temperatures ranging between 75-85°F (24-29°C) in Bangkok and the north. The northern city of Chiang Mai stays cooler with temperatures from 60-75°F (15-24°C). Southern beach destinations like Koh Phangan remain warm at 80-85°F (27-29°C). The pleasant climate creates good conditions for outdoor activities and temple visits. A TourRadar traveler mentioned "The weather in December was perfect for exploring temples and doing outdoor activities."
Are there any special festivals or events in Thailand during December?
The month starts with the King's Birthday on December 5th bringing nationwide celebrations and ceremonies. Tourist areas come alive with Christmas and New Year festivities. Chiang Mai's streets fill with night markets and traditional lantern displays. At places like the Kata Beach Resort in Phuket special holiday dinners need advance reservations. The combination of local and international celebrations makes December a lively time across the country.
What kind of accommodations are available in Thailand during December?
Since December marks the peak tourist season early booking is essential. Places range from high-end options like Na Nirand Romantic Boutique Resort in Chiang Mai to mid-range choices such as True Siam Rangnam in Bangkok. Beach destinations offer oceanfront properties including the Oceanfront Beach Resort in Phuket. As one traveler noted: "The Movenpick Hotel Bangkok and Kata Sea Breeze Resort Phuket were excellent choices for our December stay providing perfect locations for both city exploration and beach relaxation."
What are the best places to visit in Thailand during December?
The cooler weather makes this an excellent time to explore Bangkok's temples including Wat Pho and Wat Arun. Nature lovers head to the floating bungalows at Khao Sok National Park while beach enthusiasts flock to Koh Phangan and Phi Phi Islands for water activities. A TourRadar traveler shared: "Staying at the Sarana Bungalows in Koh Phangan in December was magical - perfect beach weather and the clearest waters for swimming." The mild temperatures in Chiang Mai create good conditions for temple visits and wildlife encounters.
How crowded are tourist destinations in Thailand during December?
December sees peak visitor numbers especially during the holiday season. Major attractions like Bangkok's Grand Palace Phi Phi Islands and Phuket's beaches get particularly busy. According to a G Adventures traveler: "Book accommodations well in advance especially on islands like Koh Phangan and Koh Tao. The Full Moon Party on Koh Phangan draws massive crowds if it falls in December."
Is December a good time for island hopping in Thailand?
The month offers excellent conditions for exploring Thailand's islands. The Andaman Sea along the west coast including Phuket and Phi Phi shows calm waters and good visibility.
