Fresh seafood is the speciality: grilled squid, prawns and crab, best with Kampot pepper. Simple beach restaurants on the islands serve barbecued fish in the evening.
In the city many restaurants cater to Chinese visitors; Otres and the islands have more Western-style cafés.
The expressway from Phnom Penh takes about three hours by bus or car; Sihanoukville International Airport (KOS) has a few domestic and regional flights. Speedboats run from the city’s piers to Koh Rong and Koh Rong Sanloem in about 45 to 60 minutes.
Most visitors need a visa. You can apply online for an e-visa (US$30 for a tourist visa since January 2025) or get a visa on arrival at international airports. Citizens of ASEAN countries are exempt. Check current rules, including any online arrival form, before you travel.
The islands are slightly more expensive than the mainland because supplies are shipped in. Cambodia’s currency is the riel, but US dollars are used everywhere for prices above a few dollars, and ATMs dispense dollars. Small change is often given in riel.
Beaches and islands.
Arrive in Sihanoukville, then relax on Otres Beach or take a mangrove boat trip in Ream National Park.
Take a speedboat to Koh Rong and spend the afternoon on Long Set beach.
Go snorkelling or on a night swim with bioluminescent plankton.
Move to Saracen Bay for a quieter beach day before returning to the mainland.
Be wary of online job offers in Cambodia; criminal scam operations have lured foreigners with fake jobs.
Boats can be cancelled or rough in the wet season (June to October).
Bring enough US dollars for the islands.
Bring repellent for sandflies and mosquitoes.
