G Adventures Top Destinations in Thailand.

"Adventure travel is more than a vacation. It’s a chance to get to know your world better by putting yourself on a first-name basis with the people, places, and things that make it worth exploring. This is your planet. Come and get it. We’re the small-group adventure travel experts, and have been for over 20 years. We got that way by listening to travellers and giving them what they want: Top-no... "

Thailand tours will show the “land of smiles”, sandy beaches, Buddhist temples, indigenous tribes, working elephants and possibly rice terraces, sunflowers and full-moon parties.

Below are our most visited cities, destinations and national parks in Thailand. Click on the city for more details of the destination.

Bangkok (Krung Thep Maha Nakhon) is a modern Asian city and home to more than 10 million people. It is shopper's paradise if you are interested in clothes, bags and souvenirs. If you go Bangkok, you should visit the Grand Palace (with Wat Phra Keo), the Wat Pho (with Reclining Buddha) and the Wat Arun - all conveniently in the center of the city.

Chiang Mai and Chiang Rai are two cities in the North of Thailand. Visitors use these cities to explore the jungles, visit the tribes or watch the elephants work and bath.

Kanchanaburi is a small city where two rivers (Khwae Noi and Khwae Yai) converge into the Mae Klong River. It was here that Asian forced labourers and Allied Prisoners of War built the famous "Bridge over the river Kwai" (as seen in the movie).

Khao Sok National Park in Southern Thailand is covered by an evergreen rainforest, huge limestone mountains, deep valleys, breathtaking lakes, exciting caves, wild animals and much more.

Phuket, Krabi and Koh Pi Pi are the famous beach resorts in the south of Thailand. Long white beaches, excellent hotels in every price range and the best food you can think of make this a desirable place to spend your honeymoon or next beach vacation.

Krabi is a city in Southern Thailand known for beautiful beaches and bubble mountains. There is lots to do here.

Koh Samui (Cocos palm Island) and Koh Pah Ngan are two islands at the south-east coast of Thailand. The islands have been converted from agricultural islands to mainly tourist destinations, with long white beaches, restaurants and bars. Every month there is a BIG FULL MOON party at Koh Pah Ngan where lots of youth come together to make music and have fun.

The modern town of new Sukhothai is the capital of the province. The Sukhothai Historical Park, 12 km west of new Sukhothai, contains the partially restored 13th- and 14th-century palaces and temples of the Kingdom of Siam’s first capital within its walls.
