Koh Rong Beaches Guide 2026
White sand, turquoise water, and glowing bioluminescent plankton — Koh Rong has some of the most beautiful beaches in Southeast Asia.
Overview
Koh Rong is Cambodia's largest island, located about 25 km off the coast of Sihanoukville. Despite growing tourism, most of the island remains undeveloped jungle with stunning beaches accessible only by boat or hiking trails. The island has 43 km of coastline with over 20 distinct beaches.
Quick Comparison
Long Beach (4K Beach)
