The longest beach on Koh Chang, running down the central west coast: calmer and far more spread-out than White Sand, with mid-range and upscale resorts set apart along the sand and an estuary at its middle. If you want quiet but still want food within reach, this is the beach.
Picture this: a broad strip of sand running for the best part of a kilometre, a line of coconut palms and casuarina trees behind it, a scattering of people walking the tideline, and the green ridge of Koh Chang's interior rising at your back. No thumping bars, no wall of shops crammed together. This is Klong Prao Beach — the stretch a lot of Koh Chang regulars graduate to on their second trip, because it is the island's genuine "do nothing" beach.
Klong Prao Beach (Hat Khlong Phrao) is the longest beach on Koh Chang, running for nearly 3.5 kilometres along the central west coast. It splits into a northern section (the Chai Chet end) and a southern section, divided by an estuary — the khlong that gives the beach its name. That length means people spread out: however many visitors are around, the beach itself still feels open and quiet.
Klong Prao sits just south of White Sand Beach, roughly in the middle of the island, which makes onward trips easy — to Klong Plu Waterfall, Kai Bae Beach and the viewpoints. The resorts here are mostly mid-range to upscale, set apart from one another along the sand, with restaurants and cafés on the main road within walking distance. It is not a nightlife strip like White Sand or Lonely Beach. If you are travelling as a couple or a family and want calm, this is the most comfortable base on the island.
A long beach, but each part of it feels different.
Because Klong Prao runs nearly 3.5 kilometres, you can walk a long way without crowding anyone. Early morning and late afternoon are the best times — the sand is firm enough to stroll on, the light is soft and the beach is quiet. Walk the tideline from the northern end down to the estuary, then sit under the casuarina trees. It is a simple thing, but Klong Prao does it better than anywhere else on the island because it has the room to breathe.
This is the thing no other beach on the island has. The estuary that splits Klong Prao is sheltered from wind and waves, so you can paddle a kayak inland along the khlong — past stilt houses and waterside restaurants and into quiet mangrove channels. It is an atmosphere you cannot find elsewhere on Koh Chang. Many of the resorts along the canal lend or rent kayaks. It is easiest around high tide and in the dry season, November to April.
The water at Klong Prao is fairly shallow and gentle in high season, so families with children can relax more than on rougher beaches. But the beach shelves very gradually: at low tide the sea retreats a long way and stays shallow, and you have to walk out some distance to reach water deep enough to swim. The trick is to check the day's tide times and swim around high tide, when it is easiest.
Like the island's other main beaches, Klong Prao faces west, so in the evening you watch the sun drop straight into the sea. The advantage here is space and quiet — it is easy to find a calm spot to settle, whether on the sand, reclined at a beachside restaurant, or with a drink from one of the small bars. It is a low-key way to close out the day, and one that stays with you.
Klong Prao shelves gently and is wide, which means the tide has a big effect on swimming. At high tide the sea comes in close to the treeline and is deep enough to swim comfortably — the best time to get in. At low tide the water pulls a long way out, exposing broad flats and shallow pools. Children love wandering them for shells, but if you want to actually swim you will be walking out a fair distance.
The simplest approach is to check the day's tide times (ask your resort, or use an app) and plan your swim around high tide. Low tide is better spent walking the beach, taking photos, or paddling a kayak up the khlong instead.
The best time at Klong Prao — and on Koh Chang generally — is the dry season, roughly November to April. The sea is clear and calm, the skies are bright, and the resorts, restaurants and beach bars are all open. The snorkelling boat trips out to Koh Rang and the southern islands run normally. December–January and Songkran (April) are peak: busiest and priciest for rooms. For good weather without the heaviest crowds, November and February–March are the sweet spots.
During the south-west monsoon, roughly May to October, Koh Chang gets rain and a rough sea. To be straight with you: in these months many resorts, restaurants and beach bars along Klong Prao close or run reduced hours. The snorkelling boat trips usually stop running because the sea is too rough. Koh Chang is a genuinely seasonal island — far quieter in low season than Phuket or Samui. The upsides are real: lush green jungle, full waterfalls, cheaper rooms and almost no crowds. But before you come, check in advance that the places you want are still open. The car ferry still runs across the strait, though some days the crossing is choppy.
Koh Chang is an island reached by car ferry from the Trat mainland — there is no train, no airport on the island and no BTS/MRT or metro. Once you are on the island you get around mainly by shared songthaew.
Klong Prao is a long beach with shops spread out, so you cannot walk to a vendor from every spot the way you can on White Sand. Bring enough water, sunscreen and cash (ATMs on the island are limited). Sandals that handle sand and shallow water are useful. If you plan to kayak the khlong, take a dry bag for your phone, and check with your resort whether kayaks are included.
Most of Koh Chang and the snorkelling islands to the south lie within Mu Ko Chang National Park. Tread lightly: don't leave litter on the beach or in the khlong, and don't take home quantities of coral or shells. On dive and snorkel trips, don't stand on or touch the reef. As for the island's elephant camps, if you visit, choose an experience that lets you observe, feed or bathe the elephants rather than ride them, for the animals' welfare. Klong Plu Waterfall and the marine snorkelling trips charge separate national-park entry fees, so budget for those.
