Koh Rong

Koh Rong is Cambodia's second-largest island, lying about 25 km off the coast of Sihanoukville in the Gulf of Thailand. Until the late 2000s it was a near-deserted scatter of fishing hamlets, but a tourism boom that began around 2008 — and accelerated sharply from 2012 onward — has transformed Koh Tuich (Koh Toch), the village beside the main pier, into a backpacker hub of bamboo bungalows, beach bars, and dive shops. Despite heavy development pressure, much of the 78 km² island remains thickly forested, ringed by 23 white-sand beaches and fringed reefs that draw snorkellers and divers. The island's signature attraction is its bioluminescent plankton: on dark, moonless nights the sea glows pale blue with every kick or splash, best viewed in shallow water away from village lights.

The climate is classic Cambodian coastal tropics. The dry season runs roughly November to April, with hot, blue-sky days and calm seas — this is peak time and accommodation fills up around Christmas, New Year, and Chinese New Year. The wet season (May–October) brings heavy afternoon downpours, rougher crossings, and partial closures along Long Set Beach; Sok San and Lonely Beach become harder to reach. Counter-intuitively, early-rainy-season storms produce some of the most dramatic sunsets and lightning shows of the year.

The island is loosely organised around four villages. Koh Tuich in the southeast is the arrival point and the centre of nightlife, restaurants, and budget lodging. Sok San (Bai Tau) sits on the west coast at the northern end of the 7 km Long Set Beach. Dam Dkeuw (Dam Skal) on the east coast is built partly over the water, with stilt houses giving it a Venetian feel, and Prek Sway is a quieter fishing village further up the east coast. Most travellers stay in Koh Tuich or along Long Set Beach.

By Car / Road

There are no roads to the island itself — access is by ferry from Sihanoukville, so most visitors first reach Sihanoukville by road from Phnom Penh (about 230 km, 4–5 hours via NR4) or from Kampot (about 105 km, 2–2.5 hours). Long-distance buses, minivans, and shared taxis run daily from Phnom Penh, Siem Reap, Kampot, and Kep to Sihanoukville's bus stations and hotel zones.

Ferry from Sihanoukville. Speed ferries and slower wooden ferries depart from Sihanoukville's port, with the main crossings landing at Koh Tuich pier. Crossing time is roughly 45 minutes by speed ferry; older slow ferries take about 2 hours. Combined return tickets including a tuk-tuk pickup in central Sihanoukville typically run US$10–20 depending on operator and season — confirm before paying any "extra" for transfer to the pier, as this is usually included. A small number of services land directly at Coconut Beach (Buva Sea Speed) or at Pagoda Beach; if you have booked a resort outside Koh Tuich, confirm which pier your ferry uses, as some resort owners discourage onward boat transfers between beaches.

Boarding is via a wooden plank between pier and ferry, which can be awkward with luggage or limited mobility. Bring sunscreen, a hat, and water — not all boats sell snacks on board.

On foot. Koh Tuich village and the resort strip extending north toward Monkey, Paradise, and Treehouse bungalows are easily walked along the beach in 15–30 minutes. Further afield, the jungle trails between villages are sparsely marked — OpenStreetMap is more reliable than Google for these — and a guide is strongly recommended for any trek longer than an hour.

By boat. Hiring a local fishing boat is the most practical way to reach distant beaches and villages. Typical rates: Koh Tuich to Sok San (Bai Tau) about US$25 per boat; Koh Tuich to Long Set Beach US$5–10 per person on shared runs. Resort water taxis (e.g. Pura Vita) are usually included with bookings.

By motorbike. Concrete roads now link parts of the island and a handful of guesthouses rent scooters. Roads are narrow and partly unpaved — go slow, especially after rain, and check brakes before agreeing the price.

Tuk-tuks and taxis. Effectively non-existent on the island. There are no Grab/PassApp ride-hailing services on Koh Rong.

Things to watch. ATM availability has long been an issue — bring enough US dollars and Cambodian riel for your stay. Some businesses will do over-the-counter cash advances on cards but charge around 10%. Petty theft of phones and bags from beaches has been reported; don't leave valuables unattended while swimming.

• Long Set Beach (4K Beach). A 7 km arc of fine white sand stretching from near Koh Tuich up to Sok San — arguably the most beautiful beach on the island and one of the best in Cambodia. Reach it via a 45-minute jungle trail from Koh Tuich or by boat (US$5–10). Excellent for swimming, sunsets, and viewing phosphorescence. Free.

• Bioluminescent plankton. Visible nightly year-round in calm, dark water — best in around 1–1.5 m of water on a moonless night, away from village lights. Many guesthouses (e.g. Coconut Beach Bungalows) run dedicated late-night plankton boat trips, typically departing around 21:00–02:00.

• Sok San (Bai Tau) village. A traditional fishing village at the north end of Long Set Beach. Behind the village a small lagoon and, about 5 minutes' walk into the jungle, a seasonal waterfall (wet season only).

• Dam Dkeuw (Dam Skal). A stilt village built partly over the sea on the east coast — atmospheric, photogenic, and far less touristed than Koh Tuich.

• Police Beach. A small beach immediately west of Koh Tuich, best known for late-night EDM parties (see the Do section) but pleasant by day for a swim away from the main strip.

• Pagoda Beach. A quiet, palm-fringed beach on the southwest, reached by speedboat from Sihanoukville or by trail/boat from Koh Tuich.

• Trekking with "the Walking Man" (Gil). An Israeli long-term resident based at Paradise Bungalows who has personally cut and marked many of the island's trails. He runs guided treks of 1–4 days through jungle, hidden beaches, and viewpoints. Around US$10 per person per day.

• Snorkelling and diving. Several PADI-affiliated dive shops operate out of Koh Tuich, with house-reef snorkelling directly off the village beach and boat trips to nearby reefs and Koh Rong Sanloem. Visibility is best in the dry season (November–April).

• Bioluminescent plankton tour. Most guesthouses can arrange a boat trip after dark to swim with the glowing plankton — typical price US$5–10 per person, often included in island day-tour packages.

• Island day tour. Standard full-day boat circuits include snorkelling stops, lunch at Long Set Beach, fishing, and a beach BBQ dinner with beer/whiskey. Coconut Beach Bungalows runs one for US$10 per person including dinner.

• Police Beach parties. Open-air EDM parties typically Wednesday and Saturday from 22:00 until sunrise, with a morning afterparty boat to another beach. Tickets US$10 in advance from Koh Tuich businesses, US$12.50 at the door.

• Fire shows and beach bars. Monkey Island and several Koh Tuich beachfront bars run nightly fire shows around 21:00–22:00.

• Kayaking and paddleboarding. Rentals available at Koh Tuich and several Long Set Beach resorts; the calm dry-season seas are ideal.

Eating on Koh Rong divides cleanly between cheap, good-value Khmer eateries in Koh Tuich village (mains US$2–3) and the resort restaurants along the beach, which charge more (mains US$4–8) for a better setting and broader menus. Beach BBQ dinners — typically a fish, squid, or chicken plate with rice and salad — are a near-universal evening offering at US$4–6. Vegetarian options are common (fried rice, noodle dishes, vegetable amok, fresh fruit), but strict vegan and gluten-free travellers should ask carefully, as fish sauce is in almost everything.

• Khmer village restaurants, Koh Tuich — simple open-air shacks serving lok lak, fried rice, chicken curry, and grilled fish. Mains US$2–3. Best value on the island.
• Monkey Island restaurant, Koh Tuich — Thai chef, sea-view bar, mains US$3–5, very popular at sunset.
• Treehouse Bungalows restaurant — known for wood-fired pizza, a welcome change from rice-and-noodle fatigue.
• Paradise Bungalows restaurant — elevated dining deck with good views and a more polished menu; one of the few places that purifies its wastewater.
• Coconut Beach Bungalows restaurant — relaxed beachfront, used as a meeting point for the island day tour and plankton trips.
• Pura Vita Resort restaurant, Long Set Beach — Italian-inspired menu and proper coffee bar, the most upscale option on the island.

Most beach restaurants double as bars. A can of local Klang or Angkor beer is typically US$1, draught beer slightly more, and standard cocktails (mojitos, mai tais, rum-and-cokes) run US$3–4 with widespread happy-hour 2-for-1 deals in the late afternoon.

• Monkey Bar, Koh Tuich — buckets, fire shows, and the de facto starting point for the night. Open until late depending on the crowd.
• Police Beach — late-night EDM parties Wednesdays and Saturdays from around 22:00.
• Resort bars (Paradise, Treehouse, Coconut Beach) — quieter sunset drinks with sea views.

Most non-party bars close around midnight when generators wind down; one or two Koh Tuich beach bars stay open later.

Water safety. Tap and stream water on the island is not drinkable — the brown tinge from mountain run-off in resort showers is normal but not for drinking. Stick to bottled or filtered water (about US$1 for 1.5 L). Reusable bottle refill stations exist at a handful of eco-minded guesthouses.

Power on most of the island is generator-supplied and typically only available from around 18:00 to 22:00–midnight. Bathrooms are basic, with stream-fed water that may run brown. Bring a head torch and a power bank.

Koh Rong is not a shopping destination — most travellers come for the beach and water. Small village shops in Koh Tuich sell sunscreen, basic toiletries, swimwear, sarongs, and souvenirs (shell jewellery, hand-painted T-shirts), but selection is limited and prices are higher than on the mainland.

Cash. As of recent years, there is no ATM on the island. Several Koh Tuich businesses will advance cash on a card at roughly 10% commission. Bring enough US dollars (small bills) and riel for your whole stay — US dollars are accepted everywhere, and small change is often given in riel at roughly 4,000 KHR = US$1.

Bargaining is mild on the island compared to mainland markets — boat hire and motorbike rental have some flexibility, but restaurant and bar prices are generally fixed.

• Koh Rong Sanloem — the smaller, quieter sister island, ~30 min by boat. Saracen Bay's calm crescent and Lazy Beach are highlights for travellers seeking less party and more hammock.
• Sihanoukville — 45 min–2 hr ferry back to the mainland. Worth a stop for onward transport, Otres Beach's surviving bohemian pockets, or as a launch point for further islands.
• Kampot — about 2.5 hr from Sihanoukville by road. Riverside colonial town famous for Kampot pepper, lazy boat trips, and Bokor National Park.
• Kep — ~3 hr from Sihanoukville. Sleepy seaside town beloved for its crab market and short ferry to Koh Tonsay (Rabbit Island).
• Phnom Penh — 4–5 hr by road from Sihanoukville. Cambodia's capital, with the Royal Palace, National Museum, and the sobering Tuol Sleng and Choeung Ek memorial sites.
• Koh Ta Kiev / Koh Russey (Bamboo Island) — closer-in islands off Sihanoukville (~30–60 min by boat) with rustic bungalow camps for a more off-grid extension.
