About Koh Rong
A 78-km² Cambodian island of jungle-and-sand bays — bioluminescent plankton at night and almost no roads.
Koh Rong sits in Gulf of Thailand, Cambodia, near Sihanoukville. Plan your visit for Nov-Apr — that’s when Koh Rong is at its best, with the most reliable conditions and the easiest logistics.
This guide covers what makes Koh Rong worth a trip, how to get there, what it costs, what to take, and the safety basics. Use the table of contents to jump to what you need, or read end-to-end to plan a full visit.
How to get to Koh Rong
The closest base for Koh Rong is Sihanoukville. Most travellers arrive via a regional flight to the nearest airport, then continue overland (taxi, bus or hire car) to the trailhead or visitor area. International flights to Cambodia usually route through the country’s main hub, the capital, before connecting onward.
If you’re combining Koh Rong with other stops in Cambodia, browse the Cambodia attractions hub for ideas — and use the Trip Planner to chain them into a single route.
Best time to visit Koh Rong
The best time to visit Koh Rong is generally Nov-Apr. That window offers the most reliable conditions, the safest access and the most consistent visitor services. Shoulder months either side of this window are often the sweet spot — quieter, cheaper, and only slightly less perfect.

Things to do at Koh Rong
- Island-focused exploring: make your way to the main vantage point first — it’s usually the easiest and most rewarding stretch of the visit.
- Photography: dawn and the last hour before sunset deliver the best light. Bring a wide lens for the landscape and a longer one for detail.
- Local experience: a guided walk with a regional guide adds context you won’t pick up alone, and supports the local economy.
- Day trips: see the What’s nearby section below — most visitors pair Koh Rong with at least one or two other stops in the same trip.
Safety tips
Koh Rong is rated easy. The walk-in, paths and physical demand are well within the reach of most travellers in normal health.
- Read your country’s current travel advisory for Cambodia before you go — see our travel advisories digest.
- Buy comprehensive travel insurance with adventure-activity cover. SafetyWing is an easy option you can buy after departure.
- Tell someone your route and expected return time — especially for hikes, caves and remote attractions.
- Carry water, snacks and a backup light source. Phone batteries die fast in cold or remote conditions.
- Respect cordons, fences and posted warnings — they are usually there because someone got hurt.
What to carry
- Comfortable walking shoes broken in beforehand (boots for trails, sturdy trainers for short walks)
- 1–2 L of water per person and high-calorie snacks
- Layered clothing (a warm mid-layer, a waterproof shell) — even in warm climates, weather changes fast at altitude or near water
- Sun cover: high-SPF sunscreen, hat, sunglasses
- A power bank, a headlamp + spare batteries, and a small first-aid kit
- Cash in small denominations — ATMs are unreliable in remote areas
- Camera with a wide-angle lens, plus a lens cloth (mist and spray love camera glass)
What NOT to carry / do
- Single-use plastics — many national parks have banned them; refillable bottles only
- Drones without an explicit permit — most parks and many countries prohibit them
- Food into wildlife areas — even an apple core teaches animals to associate humans with food
- Loud Bluetooth speakers — they wreck the experience for every other visitor
- Anything you wouldn’t carry up an emergency stairwell — be honest about your fitness
