Cambodia

Koh Rong

Cambodia's beach island in two halves - all-night fire shows at one end, four empty kilometres of sand at the other.

Koh Rong is Cambodia's second-largest island, 78 sq km of jungle ringed by seven bays and around 28 beaches, a short boat ride off the Sihanoukville coast. Sok San Beach runs for miles of white sand down the west side and Long Set Beach holds a clear four kilometres on the east, with the whole surrounding sea inside Koh Rong National Marine Park, Cambodia's first. The island splits sharply in two: one loud backpacker village, and long empty sand everywhere else.

Why you'll love Koh Rong

The beaches  Twenty-eight of them across seven bays - Long Set runs a clear four kilometres and Sok San goes on for miles, so twenty minutes on foot usually buys you an empty stretch.

Glowing water  Bioluminescent plankton light the shallows off the northern beaches on moonless nights, and night-swim boat trips go for around USD 5 a head.

Split personality  One village is fire shows and house music until sunrise; forty minutes up the sand it is fishing hamlets, cashew and coconut plantations and jungle.

The marine park  The water sits inside Koh Rong National Marine Park, Cambodia's first, with snorkelling straight off the boat and reef within swimming distance of several bays.

When to avoid Koh Rong

Jul-Oct is the southwest monsoon - heavy rain, crossings rough enough to cancel ferries for days, and rubbish washing up on the sand; room rates drop hard if you will gamble on it.

Top things to do in Koh Rong

  1. Long Set Beach (4K Beach) - the island's cleanest 4km of sand

    scenic nature wildlife 👍 Popular

    A 20 minute walk east of Koh Touch and a different island entirely: four kilometres of squeaky white sand with only a handful of low-key places on it, so you can walk twenty minutes and see nobody. Ferries also drop directly here, and it is the best swimming water on the east coast.

  2. Bioluminescent plankton - swim in water that lights up as you move

    nature wildlife adventure ⭐ Highly recommended

    Night boats leave Koh Touch around 7pm for roughly USD 5-12 per person, or pay about USD 17 for the afternoon combo that adds snorkelling, fishing and sunset before the plankton stop. Go on a moonless night and get away from beach lights; it works year-round but boats stay in on choppy nights.

  3. Sok San (Long Beach) - the 7km sweep where Survivor was filmed

    scenic adventure 👍 Popular

    The island's west coast is one continuous 7km beach, backed by a resort strip at the south end and a working fishing village at the north. Season 32 of Survivor was shot here. At the north end the Blob Jump launches you 4-6m off a tower onto an inflatable in the sea for about USD 3.

  4. Lonely Beach and Palm Beach - the roadless north coast

    off beaten path scenic ⭐ Highly recommended

    The far north is where people go when Koh Touch wears thin. Palm Beach is all leaning coconut palms with Speed Ferry Cambodia stopping three times a day; Lonely Beach next door is a 40-60 minute jungle walk from the road and has a single rustic resort from around USD 30-50 a night. No shops, no wifi, bring what you need.

  5. Koh Touch to Sok San jungle trek - cross the island on foot

    hiking adventure

    The classic Koh Rong walk: roughly 50-60 minutes on a jungle trail from the main beach over the spine of the island and out onto Long Beach. Go in the morning, take more water than you think, and expect mud and leeches after rain. Boats back cost a few dollars if your legs are done.

  6. Prek Ta Sok mangrove community - kayak the creek or walk the boardwalk

    nature wildlife off beaten path

    A 40 hectare community mangrove reserve set up in 2021, kept plastic-free by the villagers who run it. Entry is about USD 2 and a kayak around USD 10; the paddle out to the sea swing is flat and easy, and there is a wooden walkway through the trees if you would rather stay dry.

  7. High Point Rope Park - zipline the canopy above Koh Touch

    adventure

    Ziplines, rope bridges and treetop obstacle courses strung through the jungle at the south end of Koh Touch beach, towards Police Beach. Around USD 25 in low season and USD 35 in high season, and the last platforms come out over the water.

  8. Snorkel trip around the island's reefs and offshore rocks

    adventure nature wildlife

    Half-day boat snorkels run about USD 15 and full days with lunch around USD 25 with operators like Adventure Adam out of Koh Touch. Expect parrotfish, stingrays and the occasional turtle rather than dramatic coral. Water is clearest from December to April; wet-season trips get cancelled on rough days.

  9. Eat your way around Koh Touch and Sok San village

    food

    Beachfront charcoal BBQs of fish, squid and prawns are the island staple. Beyond that: the soup shack near the main pier for about USD 1 of Khmer chicken soup, MaLoop Cafe for beef lok lak and acai bowls, Jungle Bar and Kitchen for pizza and a cold beer, and The Chill in Sok San village for a plate over the water. Village meals still run around USD 2.

  10. Koh Touch after dark - fire shows and beach bars

    nightlife music 👍 Popular

    The nightlife is concentrated on Koh Touch beach now, with nightly fire shows and buckets at places like Funky Beach Club and Nest Beach Club. Set expectations honestly: the famous all-night Police Beach raves stopped with Covid and have not come back, so the beach south of the pier sits largely derelict.

Getting to & around Koh Rong

Getting there

Fly into Sihanouk International (KOS), 18 km by tuk-tuk to the Sihanoukville pier, then a 45-55 min speedboat to Koh Touch.

Flight

Sihanouk International Airport (KOS)

KOS sits about 18 km east of Sihanoukville and the island is a sea crossing beyond it. A tuk-tuk to the ferry pier is USD 10-15 (about 25 min), an airport taxi USD 20-25, or the airport shuttle bus USD 4 into central Sihanoukville with a short tuk-tuk on from there. From the pier it is 45-55 min on a fast ferry to Koh Touch, USD 13-17 one way. Check in 30 min before departure and never cut it fine on arrival day: nothing sails after dark, so the last boat goes around 17:00-17:30.

Ferry

Koh Touch pier, Koh Rong

The arrival that matters. Five fast-ferry operators work the Sihanoukville run - Speed Ferry Cambodia, Buva Sea, GTVC, Island Speed Ferry and Angkor Speed Ferry - at USD 13-17 one way or USD 22-27 return, crossing in 45-55 min. Roughly seven sailings a day, first out about 08:00 and last about 17:00. Most leave from the Autonomous Port, a few from Ochheuteal (Serendipity) pier, so check which pier your ticket names rather than assuming. Book ahead in the dry months through BookMeBus, CamboTicket or 12Go.

Ferry

Long Set, Sok San, Coconut and Palm beaches

Buva Sea, Speed Ferry Cambodia, GTVC and Island Speed Ferry also sail direct to beaches other than the main village, USD 25-30 return and 45-90 min depending where you fall in the stop order. Worth the extra if your bungalow is not in Koh Touch, because the alternative on arrival is a boat taxi or a sweaty jungle walk with your bag.

Coach

Sihanoukville bus offices, 10-15 min walk from Ochheuteal pier

Phnom Penh to Sihanoukville takes 5-6 hr, USD 4-6 on an economy bus or USD 8-10 VIP, then about USD 3 by tuk-tuk to the pier. Take a morning departure: miss the last ferry and you are sleeping in Sihanoukville.

Train

Sihanoukville railway station

Royal Railway runs Phnom Penh to Sihanoukville Friday to Monday only, about 6.5 hr for around USD 7, air-conditioned and pleasant but routinely 30-60 min late. Add a tuk-tuk to the pier and do not book a same-day ferry with a tight margin.

Drive

Ochheuteal (Serendipity) pier

A private car from Phnom Penh is about USD 60 and roughly 4 hr door to pier, which makes sense for two or three people with a booked sailing to catch.

Getting around

Walking

Koh Touch village is one sandy strip, 10 min end to end; everything beyond it needs a boat or a track.

Free

Cash, and in practice US dollars: boatmen, shuttle boats and guesthouses all take notes and nothing takes a card. There is no ATM on Koh Rong, so draw what you need before you leave Sihanoukville; a few Koh Touch guesthouses will do an EFTPOS cash-out at around 10% commission if you run dry.

Shuttle boat between beaches

Fixed-schedule hops out of Koh Touch to Sok San and the other beaches, arranged at the pier.

USD 6

Boat taxi to Long Set Beach

Local longtail from the Koh Touch pier, 10-15 min up the east coast.

USD 5-10

Private longtail charter

Takes about 10 people and is the only way to string several far beaches together in one go.

USD 25 per boat short hop, USD 100 full day

Jungle track to Long Set Beach

20-45 min over roots and rock from Koh Touch, slick and muddy for hours after rain.

Free

Cross-island trek to Sok San

1.5-2 hr of steep, sweaty jungle with scrambling near the far end; carry water, there is nothing en route.

Free

Motorbike hire

A few concrete lanes near Koh Touch only - the island has no road network, which is the whole point of it.

USD 10-15 per day

Day trips from Koh Rong

Sok San Beach (Long Beach)

Full day

Empty west-coast strand

Koh Rong's big one: 7 km of white sand running north from Sok San fishing village, with a handful of resorts and long stretches where you will see nobody. Most people boat one way and walk the other. A small lagoon and a wet-season waterfall sit about five minutes into the jungle behind the village.

Getting there

ferry | walk

USD 6 shuttle boat from Koh Touch, a 50 min direct ferry, or a 1.5-2 hr jungle trek

Long Set Beach (4K Beach)

Half day

Quiet east-coast beach

The nearest escape from the Koh Touch party strip, a long pale curve with a few bungalow places and almost no noise. It is also the easiest beach for bioluminescent plankton after dark, because the village lights do not reach it.

Getting there

walk | ferry

20-45 min on the jungle track from Koh Touch, or 10 min by boat taxi

Koh Rong Sanloem

Full day

Neighbouring island

The calmer sister island and a genuinely different day out: the sheltered arc of Saracen Bay, the fishing hamlet at M'Pai Bay, and a 45 min jungle path across to Lazy Beach and Sunset Beach. Ask your operator whether your Koh Rong return ticket covers the hop back, as most will but not all.

Getting there

ferry

20-40 min by inter-island ferry transfer from Koh Touch

Koh Koun snorkelling trip

Full day

Reef snorkelling island

The standard island-hopping loop: snorkelling off the Koh Koun conservation island, a village stop at M'Pai Bay and a sunset fire on the sand. Boats leave Koh Touch daily - Ankounamatata at USD 20, Adventure Adam and The Islander at USD 25 - and the cheapest local boats run USD 10 without the lunch.

Getting there

tour | ferry

Longtail tour boat from Koh Touch, roughly 12:00 to 20:00

Bioluminescent plankton swim

Half day

Night plankton swim

Boats run out to the dark beaches on moonless nights and you swim in water that flares blue-green as you move. Strictly weather-dependent: choppy seas in the wet months cancel it more often than not, and a bright moon kills the effect anyway.

Getting there

tour | ferry

15-20 min by longtail from Koh Touch after dark

Longtail circuit of the island

Full day

Full island boat loop

Charter your own boat and run the coastline: Sok San village, the palm-backed sand towards Lonely Beach, Palm Beach, a slow pass by Song Saa Private Island and the stilt village of Daem Thkov near sunset. Split across a group it undercuts the fixed tours and you pick the stops. Skippers go north or south depending on the swell.

Getting there

tour | ferry

6-8 hr private longtail charter from Koh Touch

A little history of Koh Rong

Koh Rong spent most of its modern history as four fishing villages - Koh Touch, Prek Svay, Daem Thkov and Sok San - on an island the Cambodian navy controlled and most Cambodians never saw. Fishing supported nearly everyone, the state only formalised the island as a commune in 2000, and backpackers did not arrive in numbers until the late 2000s, when a row of cheap bungalows behind Koh Touch beach turned it into the paradise stop on the Cambodia trail.

The arc since has been fast and contested. In 2008 the Royal Group won a 99-year concession to remake the island as a planned resort destination, and the years since have brought Cambodia's first marine national park, a concrete road pushed across the interior, upmarket resorts on the western bays and a grid power link to the mainland. Koh Touch still runs on hostels and beach bars, but the island around it is being rebuilt fast enough that most guidebook descriptions are a year or two out of date.

Timeline
1979-2000

The navy administers Koh Rong and the waters within five miles of it; the four villages live on fishing and outside visitors are rare.

2008

The Royal Group is granted a 99-year concession to develop Koh Rong as a planned resort island, with the master plan approved the same year.

2015

Two back-to-back seasons of the US series Survivor are filmed on the island, one of them titled Kaoh Rong, putting Sok San's sand on international television.

2018

Koh Rong Marine National Park is declared, Cambodia's first marine protected park.

2019

Koh Rong and Koh Rong Sanloem are reorganised as Koh Rong town, split off from Sihanoukville, with a resident population of roughly 4,000.

2020

Work begins on a 70 km concrete road network linking the villages and the far beaches, ending the boat-only era for much of the island.

What Koh Rong costs

Per person, per day

Shoestring

$20–35 USD /day

≈$20–35 USD

A tent or dorm bed on Koh Toch runs USD 5-15, local noodles and curries start at USD 3, draft beer is USD 1-2 and water refills cost 2,000 riel. Guesthouses, boat tickets and beach menus all quote US dollars; riel only appears as change under a dollar. Long-stay backpackers report around USD 23 a day.

Midrange

$50–85 USD /day

≈$50–85 USD

A private room or beach bungalow at USD 20-45, restaurant meals at USD 5-15 and one boat or snorkel trip at USD 10-25. Quoted in US dollars, and noticeably above mainland Cambodia because food, water and fuel arrive by boat. There are effectively no ATMs on the island, so bring dollar cash across from Sihanoukville.

Comfort

$150–300 USD /day

≈$150–300 USD

Air-conditioned resort rooms on Sok San and Long Set beaches start around USD 100, with resort dining carrying a heavy island markup and private boat transfers on top. Everything is priced in US dollars. The Royal Sands villas sit well above this band on their own.

FAQs about Koh Rong

When is the best time to visit Koh Rong?

November to June, with the sweet spot from November to February, when the northeast monsoon flattens the sea, the humidity eases and the boats run to schedule. March to May stays dry but gets properly hot. July to October is the wet season: heavy bursts rather than all-day rain, but choppier crossings and a half-shuttered island. One counterintuitive note - sandflies are worst in the dry months, so the best weather is not the best skin.

How many days should I spend on Koh Rong?

Three to five nights. One night is mostly ferry; two covers Koh Touch and the walk along to Long Set. By the third you can take a boat round to Sok San or Lonely Beach, get out on a plankton trip after dark and still have a day doing nothing. Past five the island's limits show - the same few kitchens, the same stretch of sand - unless you booked a quiet western bay precisely to do nothing at all.

What does the wet season do to the boats?

Ferries from Sihanoukville run year-round and the crossing is short, but from roughly July to October the sea sets the timetable. Sailings get thinned out or cancelled on rough days, September and October worst of all, and the small longtail taxi boats that shuttle you between Koh Rong's beaches only go when the water is calm; night plankton trips are called off on choppy water. Travelling in those months, leave a buffer day on the mainland rather than booking a flight out of Cambodia for the morning after you plan to leave the island.

Is Koh Rong safe, and how bad are the mosquitoes and sandflies?

Safe in the ordinary sense. The real risks are petty theft from open bungalows, messy nights and drink spiking on the Koh Touch strip, and the sea itself, which has no lifeguards and few marked hazards. The bugs are the more common complaint: sandflies favour the quiet, pretty sand, Sok San and the undeveloped beaches especially, and their bites itch for a week or more, far longer than a mosquito's. Cover your ankles at dawn and dusk, use repellent and avoid lying straight on the sand. Dengue is a genuine risk in Cambodia so evening repellent earns its place; malaria is negligible on the islands. Do not drink the tap water.

What are the electricity, water and wifi actually like?

Better than the island's reputation, still not mainland-grade. Koh Touch and the developed beaches now run on effectively 24-hour power off a mainland connection, but outages happen and remote bungalows still lean on generators that can cut overnight - ask before booking if you need a fan until morning. Fresh water is the chronic problem, drawn from wells and desalination, so showers can be brackish and rationed at the far ends of the island. Wifi reaches most places and 4G handles messaging and maps; do not plan on uploading video or taking a work call that matters.

Are there ATMs on Koh Rong, or should I bring cash?

Bring cash. There is no bank ATM on the island, and while a few Koh Touch guesthouses run card terminals that will hand you money, they charge heavily for it and depend on the connection staying up. Withdraw what you need in Sihanoukville or Phnom Penh before you board, bring small notes because nobody can break a large one, and assume bungalows, boat taxis and beach bars are cash only.

Do I need a visa for Cambodia?

Most nationalities do, and it is straightforward: Cambodia issues an e-visa online and a visa on arrival at the international airports and main land borders. Sort it before you head for the coast, because Koh Rong has no immigration of its own - you clear it at Phnom Penh or Sihanoukville and then take the ferry. Check current eligibility, fees and the passport-validity rule on Cambodia's official immigration site before booking, since these change.
