A mountainous, jungle-covered island near the Cambodian border, with west-coast beaches, waterfalls and stilt fishing villages
Koh Chang rises sharply from the sea to Khao Salak Phet, about 744 metres high, and its interior is largely untouched rainforest. Development is concentrated along the coast. The west coast is where most visitors stay, along a chain of beaches from White Sand Beach (Hat Sai Khao) in the north through Khlong Phrao and Kai Bae to Lonely Beach, each with its own character.
The east and south coasts are more rural, with mangroves, small fishing communities and the national park headquarters. At the southern tip, Bang Bao is a fishing village built on stilts along a long pier, while Salak Phet in the south-east is the island's oldest and largest fishing community. Inland, short trails lead to waterfalls such as Khlong Phlu and Than Mayom, and boats link Koh Chang to the smaller islands of the archipelago.
Koh Chang became part of Mu Ko Chang National Park when the park was established in 1982; the park covers about 650 square kilometres of land and sea, including 52 islands, and around 85 percent of Koh Chang itself lies within it. This protection is why so much of the island remains forested, with wildlife such as macaques, barking deer, hornbills and monitor lizards.
The island's waters were the scene of the Battle of Ko Chang on 17 January 1941, during the Franco-Thai War, when a French naval squadron from Indochina attacked Thai warships anchored off the island and sank or badly damaged several of them. The battle is remembered each year in late January at a memorial at Laem Ngop on the mainland.
Fishing remains important to the island's older communities, particularly in Bang Bao and Salak Phet, where houses stand on stilts over the water and seafood restaurants serve the day's catch of crab, squid and fish. The island attracts long-stay visitors and families, and many small resorts and restaurants are family-run.
Beach time on the west coast is the main draw, but the island rewards exploring. Visitors walk to waterfalls, hike forest trails with local guides, kayak through mangroves and along the coast, and join snorkelling and diving trips to the reefs around the smaller islands to the south. Many take a day to drive the coast road to Bang Bao for seafood on the pier, stopping at viewpoints on the way. Evenings are relaxed, with sunset drinks on the west-facing beaches and a livelier bar scene around Lonely Beach.
The best time to visit is the dry season from about November to April, when seas are calm and the sun reliable. Trat is among the wettest provinces in Thailand, and the rainy season from May to October, heaviest from June to September, brings heavy downpours and rougher seas; some boat services to the outer islands run mainly from November to May. The waterfalls are at their fullest in and after the rains.

Boats link Koh Chang with the smaller islands of the archipelago, including Ko Wai, Ko Mak and Ko Kut, mainly in the dry season. On the mainland, the ferry piers lie near Laem Ngop, where the Battle of Ko Chang memorial stands, and Trat town and airport are a short drive away. Chanthaburi, known for its gem market and old riverside quarter, is about 90 kilometres from the piers.

ExploreKoh Samui is a 229 square kilometre island in the Gulf of Thailand, about 35 kilometres off the Surat Thani coast. Once a quiet coconut-growing island with no roads, it is now the main resort island of the Gulf, with a string of beaches, a forested hilly interior and direct flights from Bangkok and several regional cities.
ExploreKhao Yai, established in 1962 as Thailand's first national park, protects more than 2,000 square kilometres of forested hills about three hours north-east of Bangkok. It is part of the Dong Phayayen-Khao Yai Forest Complex World Heritage Site and one of the best places in the country to see wild elephants, gibbons and hornbills.
