Planning Your Trip: Beating the Crowds and Saving Money
December is one of the most popular times to visit Thailand, which means a few things for travelers: higher prices and bigger crowds.
The most popular destinations will be packed, especially around Christmas and New Year’s. If you’re dreaming of a quiet beach getaway, you’ll have to do some planning.
Strategies for Avoiding Crowds
One of the easiest ways to save money and avoid hordes of tourists is to travel before mid-December. You’ll likely find lower prices on flights and hotels if you go earlier in the month.
Another option is to pick less-traveled destinations, such as Kanchanaburi (known for its WWII history and the Bridge Over the River Kwai) or Khao Sok National Park (a rainforest with a large lake and limestone karsts).
If you’re set on visiting popular spots, book your tours and activities well in advance. This is especially important for popular attractions and experiences, as they tend to sell out quickly during peak season.
Budgeting for a December Trip
Be prepared to spend more on flights and hotels in December than you would during the off-season. Booking at least three months in advance can help you snag better deals.
Keep an eye out for deals on flights and hotels, and consider staying in guesthouses or smaller boutique hotels instead of large resorts. These can often offer more authentic experiences and better value for your money.
What to pack for Thailand in December
Packing for Thailand in December is pretty straightforward. Here’s a quick list of what you’ll need:
- Light, breathable clothes. Think cotton, linen, and anything that won’t stick to you in the humidity.
- Sun protection. The sun is intense. Bring sunscreen, a hat, and sunglasses.
- Swimwear. Obviously, if you plan on hitting the beaches or pools!
- Light rain gear. It might rain, especially in the south, so a light jacket or umbrella is a good idea.
- Comfortable shoes. You’ll be doing a lot of walking.
- Insect repellent. Mosquitoes can be a nuisance, especially outside of the cities.
Alternative Destinations: Exploring Beyond the Tourist Trail
While the beaches of Phuket and Koh Samui are tempting, there are plenty of other places in Thailand to explore in December. Here are a few ideas for those who want to venture off the beaten path:

Chiang Rai: Northern Charm
Visit the White Temple (Wat Rong Khun) and the Black House (Baan Dam Museum) and explore the tea plantations. You’ll also enjoy the cooler climate in this northern city.
