At a Glance: Side-by-Side Comparison

The table hides an important nuance: both islands contain both busy and remote corners. Koh Touch on Koh Rong is the liveliest spot in the archipelago, but a short boat ride takes you to beaches where you may see no one else. Likewise, Saracen Bay on Koh Rong Samloem has a string of resorts, while the west coast remains wild.

Beaches and Scenery

Koh Rong

Koh Rong is the more dramatic island, with forested hills, a long western shoreline and beaches that vary from busy to empty. Long Set Beach, sometimes called 4K Beach, is a classic sweep of pale sand within reach of Koh Touch. Sok San Beach on the west coast is the long, quiet stretch where some of the more comfortable resorts are located, and it is a lovely place for sunset. Lonely Beach in the far north lives up to its name.

Koh Rong Samloem

Koh Rong Samloem trades scale for intimacy. Saracen Bay is a horseshoe of soft sand and calm, shallow water that suits swimming and paddleboarding. Lazy Beach and Sunset Beach on the west side are reached via jungle trails or boat and feel delightfully remote. M’Pai Bay, a fishing village at the northern tip, offers a glimpse of local island life.

Both islands are known for bioluminescent plankton on dark nights, which you can see by swimming or wading in the shallows after sunset. It is one of the most magical experiences in the region and costs nothing.

Where to Stay on Each Island

On Koh Rong, upscale travellers usually look first at resorts around Sok San Beach and at the private-island options within the wider archipelago. Our roundup of the best luxury resorts on Koh Rong covers the strongest choices, and our Koh Rong luxury trip planner explains how to fit them into a Cambodia itinerary.

On Koh Rong Samloem, the best stays are boutique bungalow resorts along Saracen Bay and smaller hideaways on the quieter beaches. Expect simple, stylish rooms, beachfront restaurants and an unhurried pace rather than full-service five-star facilities. That is part of the appeal: you trade spa menus for direct access to some of the clearest water in Cambodia.

• For couples: a beachfront bungalow on Saracen Bay or Lazy Beach.
• For families: Saracen Bay, thanks to calm, shallow water.
• For comfort and choice: a resort on Sok San Beach, Koh Rong.
• For maximum privacy: a private-island resort in the archipelago.

Getting There and Getting Around

Both islands are reached by fast ferry from Sihanoukville, the port city on the mainland. Sihanoukville has its own international airport, and Phnom Penh is linked by road and expressway. Ferries typically take around 45 minutes to an hour, with several daily departures in high season.

Once on Koh Rong, you can use roads and tuk-tuks or motorbike taxis between some areas, but boats are still the easiest way to reach remote beaches. On Koh Rong Samloem, roads are limited, so you will walk jungle trails or use boat taxis between bays. Some resorts on both islands arrange their own boat pick-ups.

Best Time to Visit

The dry season, roughly November to April, is the most reliable time for both islands, with calm seas, sunny days and good visibility for snorkelling. December to February is the most comfortable period, while March and April bring more heat. The wet season, from about May to October, brings afternoon storms and rougher crossings, though there are many bright days and far fewer visitors.

If you are combining the islands with Siem Reap and the Angkor temples, the same dry-season window works across the country. Our guide to luxury resorts in Siem Reap can help you plan the cultural half of the trip, and the Tourism of Cambodia portal lists official travel information.

Activities, Food and Practicalities

Activities on both islands are refreshingly simple. Snorkelling trips visit the reefs and small islets around the archipelago, kayaks and paddleboards are widely available, and jungle trails cross both islands for those who want to walk between beaches. Koh Rong offers more organised options, from boat tours and fishing trips to a canopy zipline and viewpoint hikes, while Koh Rong Samloem is more about swimming, reading and sunset drinks on the sand.

Food follows the same pattern. Koh Touch on Koh Rong has the widest choice of restaurants, cafés and bars, with Khmer, Western and seafood barbecue menus. On Koh Rong Samloem, most visitors eat at their own resort or wander along Saracen Bay to try neighbouring beach restaurants. Fresh grilled fish, Khmer curries and fruit shakes feature on almost every menu.

Practical tips for both islands

• Cash: carry enough US dollars or riel. ATMs are limited and can run out, especially on Koh Rong Samloem.
• Power and Wi-Fi: many properties rely on generators or solar power, so connectivity can be patchy. Ask your resort what to expect.
• Health: bring insect repellent, reef-safe sunscreen and any medication you need; medical facilities are basic, with hospitals on the mainland.
• Luggage: pack light. Many piers involve walking along sand or wading, and porters are not always available.
• Sustainability: refill water bottles where resorts offer filtered water, and avoid touching coral when snorkelling.

Respect for local communities matters too. Dress modestly when you visit fishing villages such as M’Pai Bay or Koh Touch away from the beach, and ask before photographing residents. Small gestures go a long way on islands where tourism is still relatively new.

Which Island Should You Choose?

Think about the kind of days you want. If your ideal trip includes moving between beaches, trying different restaurants and having resort-style amenities, Koh Rong gives you more options. If you want to unpack once, swim in calm water and spend evenings watching plankton glow in the dark, Koh Rong Samloem is the better match.

• Choose Koh Rong for variety, more upscale choice and longer stays.
• Choose Koh Rong Samloem for calm bays, couples and families with young children.
• Do both if you have five nights or more: start on Koh Rong Samloem to unwind, then finish on Koh Rong.
