Saracen Bay is the most popular beach on Koh Rong Samloem and a strong contender for the best beach in Southern Cambodia. The bay curves gently for nearly a kilometer, framed by calm, shallow water that stays warm year-round. Bungalow resorts line the sand directly, so you can walk from your room straight into the water. Snorkeling trips depart daily from small operators near the pier, and the shallow reef just offshore suits beginners well. Ferries from Sihanoukville take under an hour, making Saracen Bay one of the easiest Southern Cambodia beaches to reach without sacrificing scenery. Sunsets here draw a steady crowd of photographers each evening.
Lazy Beach sits on the quieter side of the island and moves at a slower pace than Saracen Bay. A single eco-lodge operates here, which keeps visitor numbers low and the sand largely untouched. Getting there takes effort: either a direct boat transfer or a jungle walk through the island's interior. That barrier is exactly what makes Lazy Beach one of the most secluded spots among the top beaches in Cambodia. Hammocks strung between palm trees face open water with no other development in sight. Travelers looking to disconnect completely, without wifi or nightlife, will find few better options on this coast.
Sok San stretches nearly 7 kilometers along the western edge of Koh Rong, making it the longest beach on the island. The sand stays powder-fine and the water clarity rivals anywhere on this coast, which places it firmly among Southern Cambodia's best beaches. A handful of resorts and guesthouses sit near the pier, while long stretches further down remain empty for most of the day. Among the best islands in Southern Cambodia, Koh Rong stands out for exactly this mix of accessibility and quiet, with direct speedboat transfers from Sihanoukville that skip the crowded Koh Touch village entirely. Sok San works well for travelers who want resort comforts without the party atmosphere found elsewhere on Koh Rong.
Long Set Beach, also called 4K Beach for its length, runs along Koh Rong's southern shore and once served as a filming location for the US show Survivor. Beach bars and mid-range resorts sit along the sand, giving it a livelier feel than Sok San while still ranking among the best Southern Cambodia beaches for space and scenery. Snorkeling spots lie just offshore, and the water stays calm enough for swimming most of the year. A boat from Koh Touch takes around 15 minutes, or travelers can hike through the jungle for a more scenic approach. Expect moderate crowds during peak season.
Koh Ta Kiev sits closer to the mainland than Koh Rong or Koh Rong Samloem, yet feels far more remote. Long Beach runs along the island's southern tip, backed by simple bamboo bungalows with no electricity grid, only generators or solar power. This raw setup keeps Koh Ta Kiev near the top of any list of hidden beaches in Southern Cambodia, though developers have already started buying land nearby. Longtail boats leave from Otres Beach and Ream Beach several times a day. Visit soon: locals and guides expect the island's untouched character to change within the next few years.
Otres is the mainland option worth considering if island transfers aren't part of the plan. Located a short drive from Sihanoukville, the beach offers a calmer alternative to the city's busier stretches of sand. Roughly 40 guesthouses line the shore, and restaurants keep music low after 10pm, which sets Otres apart from other beaches near Sihanoukville. Direct road access means no ferry schedules to plan around, a real advantage for shorter trips or families with young children. Otres also works well as a base for day trips to nearby islands without checking out of accommodation.
Kep Beach differs from the island beaches further west: a small crescent of sand facing calm, shallow water, backed by a coastal promenade and Cambodia's famous crab market. Families favor this stretch for its gentle waves and easy access, and it stands out among family-friendly beaches in Southern Cambodia for exactly that reason. On clear days, Vietnam's Phu Quoc Island is visible across the water. Kep works as a standalone day trip from Phnom Penh or as a final stop after visiting Kampot. Boats from Kep also reach Koh Tonsay (Rabbit Island), a quieter add-on for travelers with an extra afternoon.
From the lively shores of Koh Rong to the quiet crescent of Kep, Southern Cambodia's coastline offers something for every type of traveler. These seven best beaches in Southern Cambodia cover the full range: party islands, secluded eco-lodges, and family-friendly mainland stretches with easy access from Phnom Penh. Whichever spot fits your trip, plan around the dry season from November to April for calmer seas and easier ferry connections. At Autour Asia, a travel agency in Asia specializing in Southeast Asia itineraries, our team designs custom Cambodia trips that combine these beaches with Angkor Wat, Phnom Penh, and the Mekong Delta, so you spend less time planning transfers and more time on the sand.
