Things to do on Koh Chang

Waterfalls

The island's interior is a national park of steep, forested peaks, and its waterfalls are the easiest way in. Klong Plu, just inland from Klong Prao, is the most visited for good reason: a short, shaded jungle walk ends at a broad pool deep enough for a proper swim, with the falls pouring down the rock face above you. Go in the morning for the quietest water.

On the sleepy east coast, Than Mayom is the historic choice — Thai kings carved their initials into its rocks — and the trail feels far more like a hike, with tiered cascades and hardly another visitor in sight. Both falls are at their thunderous best in and just after the rainy season; late in the dry season they mellow to a trickle. Wear shoes with grip, and treat the wet rocks with respect.

Snorkelling & diving

The best underwater scenery isn't off Koh Chang itself — it's a boat ride south, around the small islands towards Koh Rang, where the water turns glassy and the coral gardens sit in easy snorkelling depth. Day trips typically hop between several reefs and a powder-sand islet or two, with lunch on board; even reluctant swimmers tend to come back converted.

Divers are well served too. The surrounding marine park has gentle, shallow sites that make this one of the more forgiving places in Thailand to learn, plus a famous wreck dive for those with certification. Conditions are best in the dry season, when visibility opens right up. Most boats leave from the south of the island around Bang Bao.

Kayaking & mangroves

For a completely different waterline, head east to Salak Khok, a huge, sheltered bay lined with one of the island's healthiest mangrove forests. Paddling here is slow-travel at its finest: glide between the roots, watch kingfishers and mudskippers, and drift past a stilt fishing village that has worked this bay for generations. The community here runs things at its own gentle pace — which is exactly the appeal.

Over on the west coast, the lagoon and river mouth at Klong Prao make an easy sunset paddle, and several beaches rent kayaks for a lazy hour offshore. No experience needed anywhere — the water in the bays is flat and forgiving. Explore the bay from the village side at Salak Khok.

Beaches & sunsets

Koh Chang's west coast is one long argument about which beach is best — the polished sweep of White Sand Beach, the calm lagoon-backed stretch at Klong Prao, the sociable sands of Lonely Beach — and every one of them faces the sunset. Wherever you're staying, the evening ritual is the same: feet in the sand, sky turning copper over the sea.

Each beach has a genuinely different personality, and picking the right one shapes your whole trip. We've written an honest beach-by-beach guide: the beaches of Koh Chang. If you're still choosing where to base yourself, see where to stay.

Elephants: a welfare note

Koh Chang means "Elephant Island", and elephant encounters are heavily advertised here. Please choose carefully. Riding is hard on the animals, and welfare standards vary widely between camps. The kinder option — and honestly the more memorable one — is an ethical sanctuary visit where you observe elephants bathing, feeding and simply being elephants, at a respectful distance and on their terms.

A good rule of thumb: if a place offers riding, shows or tricks, walk away. If it limits group sizes, lets the elephants set the pace and is transparent about where its animals came from, it's worth your money.

Jungle & viewpoints

Most visitors never leave the coastal ring road — which means the island's interior, a crumpled mass of rainforest peaks, stays gloriously empty. Guided jungle treks range from half-day waterfall loops to sweaty full-day climbs with huge views over the archipelago; going with a local guide is strongly recommended, as the trails are unmarked and the forest is genuinely wild.

For the lazy version, the west-coast road itself delivers. The hilly stretches between Khlong Son and White Sand Beach, and again south of Kai Bae, have roadside viewpoints where you can pull over for a coconut and a postcard panorama of bays and offshore islets. Sunset from the Kai Bae viewpoint is a rite of passage.

Bang Bao pier

At the island's southern tip, Bang Bao is a fishing village built out over the sea — a long wooden pier lined with seafood restaurants, little shops and a lighthouse at the far end. Come hungry: this is the island's best-loved spot for fresh seafood, eaten with the water glinting between the floorboards.

The pier is also the island's main launchpad. Snorkelling boats, dive boats and island-hopping trips to the outer archipelago mostly leave from here, so it's easy to pair a morning on the water with a long seafood lunch. Wander down in the late afternoon when the day boats return and the light goes golden.

Island nightlife

Koh Chang does nightlife its own way — barefoot, low-key and mostly happening on the sand. The heart of it is Lonely Beach, the island's backpacker enclave, where a cluster of beach bars and little venues serve up live music, fire shows and cheap drinks late into the night. It's sociable rather than wild: the kind of place you arrive alone and leave with plans for tomorrow.

Elsewhere, evenings are gentler — reggae bars tucked into Kai Bae, mellow beachfront spots along Klong Prao, and a livelier strip of bars up at White Sand Beach. Whatever your speed, the night starts the same way everywhere: with the sunset.
