Thailand

Thailand spans tropical paradise and mountain jungle, from the world-famous limestone karst islands and turquoise waters of the Andaman Sea and the Gulf of Thailand to the cool, forested hills of the north, where Doi Inthanon rises to 2,565 m as the country's highest point. Over 100 national parks protect rainforest, waterfalls, and rich wildlife.

Add gilded Buddhist temples, a famously warm culture, and superb food, and Thailand becomes one of the most rewarding and accessible outdoor and adventure destinations in Asia.

Snorkel and dive the coral and karst islands of Krabi, the Similans, and Koh Tao, kayak the sea caves of Phang Nga Bay, trek the jungles and hill-tribe country around Chiang Mai, and hike the waterfalls and cloud forest of Khao Yai and Doi Inthanon. Ethical elephant sanctuaries and rock climbing at Railay add more.

The cool, dry season from November to February is the best time to visit — comfortable for trekking and ideal for the islands and diving. March to May is very hot; the monsoon (roughly June–October) brings rain and rougher Andaman seas, though it greens the jungle and lowers prices.

Asian elephants, gibbons, hornbills, gaur, and the occasional tiger and clouded leopard inhabit the national parks, while the seas host whale sharks, sea turtles, and reef fish. Khao Yai and Kaeng Krachan teem with wildlife within reach of Bangkok.

Thailand's dramatic scenery owes much to limestone karst, eroded into the sheer islands of the Andaman and Phang Nga, riddled with caves and sea caves, while the forested mountains of the north are the southern reach of the Himalayan ranges. Coral reefs fringe the warm seas.

Thailand is the heart of old Siam, never colonized, with a continuous monarchy and Theravada Buddhist culture reflected in temples and traditions across the land. Ancient capitals at Sukhothai and Ayutthaya stand amid the central plains' rivers and ruins.

Thai culture centers on Buddhism, family, and food — temple festivals, floating markets, and the spirit of sanuk (fun) — set among rice paddies, rivers, and forested hills. Northern hill-tribe communities maintain distinct traditions and crafts.

Visit November–February for the best weather, and choose the Andaman or Gulf coast depending on the season's winds. Pick ethical, no-riding elephant sanctuaries, use reef-safe sunscreen, respect temple dress codes, and combine islands with the cooler northern jungles.
