There used to be a very basic road network on the island which was built during the French Protectorate. Now however, the roads are barely visible and have been overgrown with vegetation. A reminder of this era is a light house in the south. This has been turned into a small tourist attraction and can be reached by foot via a 1 hour jungle walk.

Small reefs and the rocky surfaces of the sea waters are home to a fantastic variety of marine species. Divers and snorkelers regularly emphasize the abundance of delicate miniature eco-systems, seahorses, and nudibranches (see: Snorkelling on Lazy Beach, Koh Rong Samloem).

The Geography of Koh Rong Samloem

Koh Rong Samloem (also romanized as Kaoh Rong Sanloem) is located in the Gulf of Thailand, about 25km (16mi) off the coast of Sihanoukville and 4km (2mi) south of Koh Rong Island (a short 20 minute ferry trip away – see video map).

Koh Rong Samloem is roughly 9km long (north to south), 4km wide (east to west), and 1km wide at its narrowest point. The terrain on Koh Rong Samloem is mainly hilly, with a few medium-sized mountains and a maximum height of 210m (689ft) in the north-west.

Most of the island’s interior is covered in jungle forestry, with the coastline being characterised by sandstone rock formations and several beautiful beaches (there are three yellow sand beaches on the island’s western coast, 2 of which have been developed to accommodate tourism – Lazy Beach and Sunset Beach. Read our Ultimate Koh Rong Beach Guide to learn more)). The eastern side of Koh Rong Samloem is characterised by bays and headlands. This side faces towards the mainland and is less affected by weather conditions and the monsoon. Take a look at this video for some beautiful scenes of Koh Rong Samloem’s landscape:


A fantastic feature of the island is the 3km crescent shaped Saracen Bay Beach. The beautiful bay got its name from a British survey brig, HMS Saracen, that charted the area in the late 19th century. This is now the main tourist area on the island (see above).

To the north of Koh Rong Samloem is the uninhabited island ‘Koh Koun’, followed by its stunning sister island Koh Rong.

History of ‘Koh Rong Samloem’

Inconsistencies on whether ‘Samloem’ or ‘Sanloem’ is the correct spelling date back to the 19th Century. Early divergence came from the map makers during French rule.

The word “Sanloem” translates to: 1) Drowsiness; 2) Far out and hard to discern. There is some uncertainty over the history of the word ‘Rong’ – Some islanders say that it refers to a historical person’s name, while others think it might refer to an old term for ‘cave’ or ‘tunnel’, or to the phrase ‘shelter island’.

Marine Protection on Koh Rong Samloem

Cambodia has finally launched it’s very first large-scale marine protection project – Several areas (totalling about 405km²) around the Koh Rong islands are now ‘Marine Fisheries Management Areas’.

A: There are now 5 modern ferry services from Sihanoukville to Koh Rong Samloem – Speed Ferry Cambodia, Island Speed Boat Cambodia, Buva Sea, Angkor Speed Ferry, and GTVC. (There are also a couple of $5-$10 ‘Slow Boat’ services that take 1.5 – 2.5 hours – These services are not professionally run and are not recommended).

It will take about 40 minutes to get to the island if it’s the first stop. If the boat first stops elsewhere, it may take 1 hour or so.

All 5 services will charge roughly $25 return, though prices can vary depending on time of year, special offers, etc. All services leave from the Ochheuteal (AKA ‘Serendipity’) pier in Sihanoukville and go to the main tourist beach (Saracen Bay) on the island. If your hotel is not on Saracen Bay, please read Sihanoukville to Koh Rong Samloem.

The 5 services offer modern speed boats with comfortable chairs, life jackets, and the option to buy food and drink on board. Not all of the ferries have air-conditioning, but once the boats set off there is a strong cool breeze throughout the sitting areas which more than makes up for it.

All ferry services tend to be very busy – we strongly recommend you buy your tickets in advance. You can buy your tickets online now here: Book Ferry Tickets Online Now
