Day-tripping & the last boat

Cambodia’s coastline hides a beach that looks photoshopped. On the western side of Koh Rong, Long Beach unrolls for kilometres of soft white sand against water in three shades of blue — the kind of place foreign travellers fly across the world for, sitting quietly a couple of hours from our own doorstep. It is the antidote to a city week: no traffic, no horns, just the sea doing its thing.

Koh Rong has two faces. There’s the busy main pier at Koh Touch, with its backpacker bars and late-night noise — fun if that’s your scene. And then there’s Long Beach (the long Sok San stretch), which is everything Koh Touch isn’t: wide, calm, and empty enough that you can walk for twenty minutes and pass almost no one. This is the side to aim for if you want the postcard rather than the party. Bungalows and small resorts dot the treeline, the snorkelling is good just offshore, and the sunsets go on forever.
The water that lights up

The thing that turns a good beach trip into a story you tell for years happens after dark. On the right nights — usually away from bright lights, when the moon is low — the shallows fill with bioluminescent plankton, tiny organisms that glow electric blue when the water moves. Wade in, swish your hand, and the sea sparkles around your fingers like cold fire. Walk along the wet sand and your footprints light up behind you. It’s completely natural, completely free, and genuinely unforgettable. Go on a darker night, get away from the bars, and give your eyes time to adjust.
Two hours from the mainland, and you’re somewhere that doesn’t look like it should be free for us to enjoy. It is.
Beyond lying on the sand, there is more to do than the island lets on. The water off Long Beach is calm and clear enough for easy snorkelling straight from shore, and you can rent a kayak to paddle the quieter coves. A rough jungle track crosses the island’s spine connecting the beaches — a sweaty but rewarding hour through forest loud with birds and insects. And the eating is half the point: beachfront shacks grill the day’s catch, squid and prawns and whole fish, at prices that embarrass the mainland tourist strips. Order, wait, watch the sun drop, and eat with your feet in the sand.
One distinction helps with planning: Koh Rong is the bigger, livelier island, while its neighbour Koh Rong Sanloem is smaller and sleepier, so choose based on the trip you actually want. Long Beach on Koh Rong threads a nice middle line — beautiful, but with somewhere to find a cold drink. Whichever you pick, travel light on the island’s patience: carry every bottle and wrapper back out, never touch or stand on the coral, and accept that the power can be limited and the internet patchy — which is arguably the best thing about the place. For a country whose beaches rarely make the brochures our neighbours dominate, this stretch of sand is a quiet reminder that Cambodia’s coast can hold its own.
A little planning makes the trip smooth. The ferry from Sihanoukville takes roughly half an hour to fifty minutes depending on the operator and the sea; sailings start around 7:45 in the morning and the last boats back leave mid-afternoon, so a rushed day trip really doesn’t do the island justice — try to stay at least one night. Buy your round-trip ticket in advance in high season, keep the schedule on your phone, and build in a buffer, because missing the last ferry means an unplanned (and pricey) extra night. The dry season, November to May, gives you the calmest crossings and clearest water; in the rainy months the sea can turn choppy and some sailings get cancelled outright.
Once you’re there, the rules of a good island weekend are simple. Bring cash — ATMs are scarce and unreliable on the island. Reef-safe sunscreen and a dry bag earn their place in your luggage. Don’t leave valuables unattended on the sand. And slow down: the whole appeal of Long Beach is that there’s nothing you have to do. Swim, eat fresh seafood with your feet in the sand, nap in a hammock, and stay up for the plankton. It’s our coastline. Use it.
