Koh Rong - The Most Beautiful Island in Cambodia (2026 Update)

Koh Rong at a Glance (2026 Quick Facts)

Lying 25 kilometers off the coast of Sihanoukville in the Gulf of Thailand, Koh Rong covers 78 km² of lush sandstone hills, tropical rainforest, mangrove estuaries, and 43 km of coastline. Since the completion of the 60 km submarine power cable from the mainland and roughly 70 km of concrete roads across the interior, the island combines effortless modern comfort with untouched bays.

• Main Entry Port: Sihanoukville Autonomous Port (fast ferries take 30–45 minutes to Koh Touch or Long Set Pier).
• Best Time to Visit: November to April (sunny skies, calm turquoise water, 28–31 °C).
• Main Villages & Hubs: Koh Touch (main pier & nightlife), Long Set / 4K Beach (upscale & social resorts), Sok San Village (west coast sunsets), Prek Svay (northern fishing village), and Daem Thkov / Coconut Beach.
• Money & ATMs: US Dollars (USD) and Cambodian Riel (KHR) are used everywhere. Bring crisp cash from the mainland — there are still no reliable international bank ATMs on the island, though Bakong KHQR and card cash-outs (8–10% fee) are available.
• Connectivity: 24/7 national grid electricity and fast 4G/LTE mobile data (Smart & Metfone) in all main bays.

Why Visit Koh Rong in 2026?

Few islands in Southeast Asia offer the contrast found on Koh Rong today. Unlike Thailand's heavily urbanized islands, Koh Rong still has no high-rise buildings, no traffic jams, and miles of coastline where your footprints are the only ones in the silica-white sand. Yet the infrastructure upgrades of 2022–2026 mean you no longer have to sacrifice air conditioning, hot showers, or reliable Wi-Fi.

• World-Class White Sand Beaches: From the 7-kilometer sweep of Sok San (Long Beach) on the west coast to the calm turquoise curve of Long Set (4K Beach) and Coconut Beach on the east coast, the sand on Koh Rong squeaks underfoot like powdered sugar.
• Bioluminescent Plankton Year-Round: When night falls, microscopic dinoflagellates in the warm waters of the Koh Rong Marine National Park glow electric blue-green whenever you move your hands and feet in dark coves.
• Protected Marine National Park: Established in 2018 across 524 km² of sea and islands, the park protects shallow fringing coral reefs, seahorses, sea turtles, giant clams, and mangrove nurseries.
• Easy Day Trips to Koh Rong Sanloem: Just 15–20 minutes south by speedboat lies smaller Koh Rong Sanloem, famous for horseshoe-shaped Saracen Bay, M'Pai Bay village, and Lazy Beach.

How to Plan Your Trip Step by Step

Getting to Koh Rong and choosing the right base is simple once you know how the island is laid out:

• 1. Pick the Right Beach for Your Style: Stay on Long Set (4K Beach), Pagoda Beach, or Coconut Beach for calm morning seas and easy boat access; choose Sok San (Long Beach) for west-coast sunsets and upscale resorts; pick Koh Touch for nightlife and budget hostels.
• 2. Travel from Phnom Penh, Siem Reap, or Kampot: Thanks to the Phnom Penh–Sihanoukville Expressway, vans and buses reach Sihanoukville Autonomous Port in just 2.5 to 3 hours ($12–$16). From Siem Reap, take an overnight sleeping bus or a direct 1-hour flight to Sihanoukville (KOS).
• 3. Book a Morning or Midday Speed Ferry: Five speedboat operators (GTVC, Buva Sea, Speed Ferry Cambodia, Island Speed Ferry, Romny Tour) run daily between 08:00 and 16:30 ($25 round-trip). Tell the crew your exact pier so you land closest to your hotel.
• 4. Withdraw Enough USD Cash Before Boarding: Stop at an ABA Bank or Canadia Bank ATM in Phnom Penh, Kampot, or Sihanoukville before heading to the ferry terminal, and download the Bakong Tourists app for QR payments.
