1. Bangkok
Whether you're traveling by tuk-tuk through the crazy streets, cycling along backroads, or taking a longtail through the khlongs, the journey in Bangkok is definitely half the fun. Drop into the stunning Grand Palace, see the reclining Buddha at Wat Pho, and wind your way through floating markets.
2. Chiang Mai
This northern capital is overflowing with experiences. Temple-hop through some - or all - of its 300 temples, take a cooking class to learn the secrets of Thai cuisine, and explore the Night Bazaar for delicious food, designer goods, and a foot massage to die for.
3. Ko Tao
If you ever wondered what was below Thailand's turquoise waters, this is the place to look. Learn to dive or pull on snorkeling gear to discover the fish and reefs that call this coastline home. Shark Island is close by for adrenaline seekers.
4. Hilltribe Country
Thailand's north is home to many of the country's minority groups. A hike along buffalo tracks will take you through colorful H'mong, Karen, and Lisu villages. Spend a night as their guest for a unique insight into their life.
5. Ayuthaya
Modern meets ancient in Ayuthaya. The current city intertwines itself with the remnants of what was once one of Asia's great capitals. Walk the streets in search of clues to its imperial past and hire a bike to ride through the countryside, exploring the area's ruins.
6. Sukhothai
This former capital is a history buff's heaven. Nicknamed the 'Dawn of Happiness', Sukhothai still recalls Siam's golden age with its superb statues, marvelous monuments, and lotus flowers in full bloom. A trip to the night market is a real eye-opener; try everything from fried rice to fried bugs.
7. Krabi
The waters surrounding Krabi are dotted with hundreds of limestone karst islands. Kayakers and rock climbers will love exploring them, while others can travel to the nearby floating villages or just relax on one of the region's perfect beaches.
8. Golden Triangle
The area where the Thai, Laotian, and Burmese borders meet has long been associated with colorful cultures and illicit opium trade. The opium may have gone but the color hasn't and the markets offer all sorts of amazing local handicrafts.
9. Khao Sok National Park
For a real jungle experience, spend a couple of days in Khao Sok National Park. Thick rainforests, limestone cliffs, waterfalls, and mountains make a wild playground.
10. Kanchanaburi
This tranquil town is the jumping-off point for visits to the infamous Hell Fire Pass and River Kwai. Be sure to take a ride along the tracks of the Death Railway and reflect on the atrocities of war at the Jeath War Museum.
