Hello Friends,
Most Cambodia island-hopping guides are written by people who spent three nights in a beach hut and called it research. I actually lived out there — my first stretch in the country was on Koh Rong Sanloem, and I spent a good while bouncing back and forth from the mainland — so this is the real version. The islands are genuinely beautiful, they’re a fraction of the price of Thailand’s, and living on one is a lot harder than a holiday makes it look. Here’s how the islands actually work, which is which, and how to plan your time honestly.
How You Get to the Islands
Everything starts in Sihanoukville, over in Preah Sihanouk province. I spent a few days bouncing through there myself, back and forth to the island, and I’ll be straight: it’s more transit town than destination. Most people minimize their time there and maximize their time offshore, which is the right call. From the pier, fast ferries run out to the main islands throughout the day — the crossing to Koh Rong Sanloem takes about half an hour and costs somewhere around fourteen dollars. Boats fill up and schedules shift with the weather and the season, so buy your ticket ahead in high season and don’t cut the timing fine.
Once you’re out there, hopping between the two big islands is easy and cheap, but service to the smaller, rougher islands is thinner — plan those as committed stays, not casual day-trips.
Koh Rong Sanloem: Where I Lived
Koh Rong Sanloem is the quieter of the two headline islands, and it’s the one I know from the inside. This is where I landed when I first arrived in Cambodia, and I wrote the whole arc of it honestly — the good, the slow, and the parts nobody puts on a postcard:
- My first week living on the island and the month-one reality check
- Getting sick out there — island life unfiltered
- The slow-living side — art, piers, and beachcombing
- When paradise starts to feel like a golden cage
The short version: Saracen Bay is the main horseshoe of soft sand and calm water where most accommodation clusters, while M’Pai Bay on the north end is smaller, scruffier, and more of a community. It’s stunning and it’s peaceful — and it’s also remote, with limited power, few shops, and a real “you’re on island time now” adjustment. A few nights of it is heaven. Longer than that, and you start to feel the walls of the golden cage, which is exactly the honest lesson I took from it.
Koh Rong: The Bigger, Louder Sister
Right next door, Koh Rong is the developed one — more infrastructure, more beach bars, and the party scene the islands are known for, alongside genuinely gorgeous stretches like the long white sand of Long Set Beach. It runs the full range, from cheap backpacker hostels to a handful of nicer resorts. If Koh Rong Sanloem is where you go to slow all the way down, Koh Rong is where you go if you want some nightlife within reach of the quiet. Plenty of people split their island time between the two — party-adjacent one night, dead silent the next — and that combination is the classic first-timer move.
The Rougher, Quieter Islands
Beyond the two big names, the archipelago gets more basic and more back-to-nature, and here I’ll flag honestly that I’m pointing rather than reporting — these are the islands I’d steer a certain kind of traveler toward, not ones I’ve lived on. Koh Ta Kiev is the barefoot, eco, treehouse-and-hammock island — limited electricity, minimal development, and a deliberate lack of comfort that’s the whole appeal for the right person. Koh Thmei, inside Ream National Park, is even quieter and more about the wildlife and mangroves than the beach bars. Down toward Kep on the far side of the coast, tiny Rabbit Island (Koh Tonsay) is an easy, simple day-trip or one-night escape rather than a full island stay.
Island Holiday vs. Island Life
Here’s the honest advice I wish someone had given me. A Cambodian island is a fantastic place to visit and a genuinely challenging place to live. The isolation that makes it magical for a week — no traffic, no schedule, no noise — is the same thing that wears on you over months. The infrastructure is thin, getting anything (or anyone medical) is a boat ride away, and “island time” cuts both ways. So plan your trip with clear eyes: come for the beaches and the quiet, give it a handful of nights, and don’t romanticize a permanent move without spending real time first. I did the permanent version, and it’s why I now live inland in Siem Reap.
Planning Your Island Time
For a first Cambodia trip, a few nights on the islands slots neatly onto the end of the classic route — temples up in Siem Reap, a day or two in Phnom Penh, then down to the coast to finish on the sand. Green season (May–October) means cheaper, quieter islands but rougher crossings and more rain; dry season is calmer water and bluer skies but higher prices and fuller boats. Book ahead in peak months, because island beds genuinely run out.
For where the islands fit in the bigger picture, see my best places to visit in Cambodia and the practical side in my Cambodia travel guide. And if the temple town is your next stop after the beach, it’s all in my Siem Reap travel guide. The islands gave me my start in this country — come see why, just come with honest expectations. Cheers.
