White Sand Beach (Hat Sai Khao)
The island's longest-established beach and still its front door. White Sand Beach is a long, handsome stretch of pale sand backed by the fullest line-up of facilities on the island: hotels at every level, restaurants, pharmacies, ATMs, minimarts and a lively evening strip. If it's your first time on Koh Chang, or you're travelling with family and want everything within a short stroll, this is the easy choice.
The trade-off is that it's the busiest beach — though "busy" by Koh Chang standards is still gentle, and the northern end quietens down considerably. The sand shelves gradually into the sea, swimming is easy in season, and the sunset view down the full length of the beach is one of the island's best. Explore the area guide: White Sand Beach.
Klong Prao
A few bays south, Klong Prao is the island's long, calm middle: several kilometres of wide sand split by a lagoon and river mouth, with resorts spaced generously along it. The feel is unhurried and roomy — even in high season you can walk a few minutes and have a stretch of beach nearly to yourself.
This is the beach for couples and families who want comfort without a scene: resort pools, beachfront massage, kayaks on the lagoon, and Klong Plu waterfall just inland. There's no single centre — restaurants and shops cluster along the road — so you'll wander or hop a taxi for variety. What you get in exchange is space, calm water and the prettiest lagoon-and-palms scenery on the island. Explore the area guide: Klong Prao.
Kai Bae
Kai Bae is the beach that feels most like a village. The sand is narrower than its northern neighbours and comes and goes with the tide, but the setting makes up for it: a cluster of jungly islets sits just offshore, turning every sunset into a photograph. The village behind the beach has real life to it — family-run restaurants, little bars, tour shops and rental places, all walkable.
It suits travellers who want a bit of everything: comfortable mid-range stays, kayaking out to the islets, good eating, and a relaxed drink in the evening without a party scene. The viewpoint on the road just south of the village is one of the island's iconic panoramas. Explore the area guide: Kai Bae.
Lonely Beach
The name is a relic — Lonely Beach is the island's backpacker heart, and the most sociable place on Koh Chang. The vibe is barefoot and easy-going: cheap bungalows and hostels in the trees, beach bars with fire shows and live music, and a crowd that skews young, friendly and international. The actual beach is a compact curve of sand at the north end, with the "village" — a lane of bars, cafés and tattoo studios — set just behind.
Come here to meet people and stay out late; look elsewhere if you're after quiet luxury or family calm. Days are slow, nights are long, and budgets go further here than anywhere else on the west coast. Explore the area guide: Lonely Beach.
Bang Bao & Klong Kloi
At the island's southern tip, the road ends at Bang Bao — the stilted fishing village whose long pier is famous for seafood and boat trips. The swimming beach here is Klong Kloi, just east of the village: a sheltered, shallow bay of calm water, casual beach bars and a noticeably mellow pace. It's a lovely spot for families and anyone who wants slow days by flat water.
Basing yourself down south puts you closest to the snorkelling and dive boats that leave from the pier, and furthest from everything else — the trip up to White Sand Beach is a proper drive. Many visitors think that remoteness is exactly the point.
The quiet east coast
Cross to the east side and the tourist island falls away. This coast is about bays rather than beaches: the huge mangrove-lined inlet at Salak Khok, the deep fjord-like harbour of Salak Phet, and small fishing communities such as Dan Mai along the shore road. There are a few modest strips of sand at the far southeastern tip, but you come here for stillness, stilt villages and green water views, not sunbathing.
Stay on this side if you want the island as it was: a handful of quiet resorts and homestays, kayak trips through the mangroves, and evenings where the loudest thing is the tide. It's also an easy, rewarding day trip by scooter from the west coast.

Beach questions, answered
Can you swim on Koh Chang all year round?
Mostly, yes — but with a seasonal caveat. From November to April the sea on the west coast is typically calm and inviting. During the monsoon months, roughly June to October, swell and currents pick up on the west-facing beaches, and on rough days it is safest to stay out of the water. Watch for warning flags, ask locally, and never swim in surf after drinking.
Are the beaches on Koh Chang free to use?
Yes. All beaches in Thailand are public, including every beach on Koh Chang — you can walk, swim and lay your towel anywhere along the sand. Resorts may reserve their own loungers for guests, but the beach itself is never theirs, and beach bars and restaurants are generally happy for you to settle in as a customer.
Which Koh Chang beach is best for sunset?
Almost all of the main beaches face west, so you are spoilt for choice — every evening ends with the sun dropping straight into the sea. Kai Bae is a favourite for its offshore islets silhouetted against the sky, White Sand Beach delivers the classic long-beach panorama, and Klong Kloi in the south pairs sunset with calm water and a mellow beach-bar scene.
