Coastal gateway to pristine Cambodian islands
Updated
Sihanoukville is Cambodia's primary coastal city, situated on the Gulf of Thailand in the southwest of the country. Known locally as Kampong Som, it serves as a hub for beach tourism and island access, with several offshore islands making it one of Southeast Asia's most accessible tropical island destinations.
Sihanoukville is in Cambodia, Southeast Asia, about 190 km south-west of Phnom Penh in a straight line. The closest other destination in our Cambodia guide is Kampot, roughly 70 km away. Its coordinates are 10.6093° N, 103.5296° E.

The city itself has undergone dramatic and controversial changes since around 2017, when significant Chinese investment transformed much of the urban core with casinos and high-rise construction. This development altered the character of the city centre and of previously laid-back beaches such as Ochheuteal and Serendipity. Following the Cambodian government's ban on online gambling in 2019, much of this construction halted and the city is in a transitional phase, with the beach areas recovering their earlier character.
Otres Beach, located around 7 kilometres south of the city centre, remains the most appealing beach for independent travellers, with lower-key development and a more relaxed atmosphere. Independence Beach to the north retains a relatively peaceful setting and is accessed via the Independence Hotel grounds.
The offshore islands are the principal draw for many visitors. Koh Rong is the largest, approximately 45 kilometres from Sihanoukville by fast ferry, offering white-sand beaches and bioluminescent plankton in the surrounding waters after dark. Koh Rong Samloem to the south is smaller and quieter, popular with travellers seeking less developed conditions. Several smaller islands are accessible on day trips. The fast ferry to Koh Rong takes approximately 45 minutes.
Ream National Park, located about 18 kilometres east of the city, encompasses mainland forest, mangroves, estuaries, and 21 offshore islands. Boat tours through the park's waterways provide access to dolphin habitats and coastal bird populations. The park's condition varies with seasonal water levels.
The best time to visit Sihanoukville and its islands is November through April, when the Gulf of Thailand experiences calmer conditions and less rainfall. The monsoon season from May through October brings rough seas that limit access to some islands.
When to go
Sihanoukville sits on Cambodia's south coast on the Gulf of Thailand, tropical and warm year-round. The dry season from November to April brings calm seas, sunshine and the best island-hopping - peak time. May to October is the southwest monsoon: hot, humid and rainy with rougher seas, but the beaches empty out and prices drop sharply.
Attractions
Sihanoukville (locally “Snooky”) is most travellers' jumping-off point for the stunning Koh Rong islands, but the town itself has beaches, sunsets and seafood worth a stop. Many visitors now skip straight to the islands - if you do stay, base yourself on the quieter beaches west of the centre.
The reason most people come - two gorgeous islands of white sand, turquoise water and jungle interiors. Koh Rong is the lively one (beach bars, bioluminescent plankton); Koh Rong Samloem is the quiet, Robinson-Crusoe escape. Day trips or overnight both work.
Speed ferry ~$25 round trip; 45 min to Koh Rong.
The best of the mainland beaches - a long, relaxed arc of sand south of town with beach bars, bungalows and kayak rentals, far calmer than the central strips. The default base if you stay onshore.
Cleaner, quieter beaches backed by resorts - Sokha is a beautiful crescent (a small day-fee may apply), Independence has a historic jetty and great sunset views.
A protected mangrove and marine park north of town with dolphin-watching boat trips, jungle trekking, empty beaches and birdlife - a great escape from the beach bars. A half- or full-day by boat.
Park entry ~US$1; boat tours from ~$15-25.
Serendipity Beach is the social hub for sunset drinks, and the Golden Lions statue is the town's landmark meeting point - lively and central for nightlife.
For a taste of local life, browse the fresh-produce stalls at Phsar Leu and climb to Wat Leu on the hill for panoramic views over the coast.
Transport
Sihanoukville has its own airport (KOS), road and bus links to Phnom Penh and Kampot, and regular ferries to the islands.
From Sihanoukville, combine the islands with the riverside chill of Kampot or loop back through Phnom Penh.
Accommodation
Most travellers head straight to the islands, but onshore there's a beach for every budget west of the busy centre.
The pick of the mainland - beachfront bungalows, hostels and boutique stays with a laid-back vibe, well removed from the casino development near the centre.
Close to the bars, ferries and budget eats - convenient and social, if louder.
Big resort hotels on the cleaner, quieter northern beaches with pools and private sand - the splurge pick.
For many, the real destination is Koh Rong or Koh Rong Samloem - beach bungalows and hostels from budget to barefoot-luxury.
Food & drink
As a coastal town, Sihanoukville's specialty is fresh seafood - crab, prawns, squid and fish grilled on the beach - alongside classic Khmer dishes.
Grilled seafood platters - crab, prawns and squid by the kilo at beach shacks. Amok and loc lac feature everywhere, often with a coastal seafood twist. Fresh fruit shakes and $0.50-1 beers flow at happy hour.
Plan your trip
Visas, currency and language are as for the rest of Cambodia: a 30-day visa-on-arrival or e-visa (US$30 as of November 2026), US dollars accepted everywhere, and English spoken at tourist spots. Note: central Sihanoukville saw heavy casino development - most travellers now head straight for Otres Beach or the islands for a better experience.
