Scuba Diving - Dive Sites

The islands off the coast present some amazing diving with an incredible diversity of hard and soft corals, a large collection of reef fishes, larger pelagics and an enormous variety of macro-life. Most of the off-shore islands are uninhabited and between dives you can relax on the white sandy beaches or snorkel off the shore. All of our dive sites are at least 1 1/2-2 hours from the mainland in order to provide the best quality visibility available. We choose the dive sites for suitability depending on the experience of the divers, weather and prevailing wind. Most of the dive sites are fringe reef dives, best explored from a boat. Often there are mild currents on the dives, which is great as you get to see a lot of the site with minimum effort and of course we make sure either our speedboat or the dive boat picks you up, so there's no hard work having to swim back.

Koh Tang is situated around 4-5 hours off the mainland about 2 1/2 hours south-west of Koh Rong Saloem. It has 2 or 3 sandy beaches, the rest being rocks. There is a small Cambodian military presence on the island, but otherwise it is uninhabited. Visibility ranges from 10-30m with average vis being around 15m. Its remoteness from the mainland makes this a very exclusive trip.

  • Explosion Reef
    An off-shore reef formation which runs between Koh Tang and a small island to the west, this dive site varies in depth from 6m down to 18m. The reef here is made up of fields of staghorn coral to the north which give way to coral bommies and rock outcroppings further south. The staghorn coral acts as a nursery and "explodes" with the dazzling colours of juvenile fish and marine life. This site also boasts our only trigger fish (a titan), so far only spotted by a select few divers, and some of the best visibility in the area.
  • Three Bears
    A favourite site, this gets its name from the formation of caves in the cliff on the shore (there is a tall one, flanked by ones slightly smaller on either side). The reef begins at around 2m and bursts with bright corals and a wealth of marine life which extends to a sandy bottom at around 16m. You often find yourself followed by schools of batfish, and over the sand you encounter larger fish such as schooling trevally (jacks) and barracuda.
  • Giraffe Lookout
    Another popular site, and another weird name, which comes from the shape of a tree perched on the top of the overlooking cliffs (you have to see it). A mix of hard and soft corals, this reef pulses with life and vibrant colours. Marine worms abound here as do many different nudibranch, box and puffer fish. Again, over the sand there are schooling trevally and larger fish such as cobia.

  • Atlantis
    This is a large reef descending from the shallows to around 16m and extending far out into the bay. The first part of the reef down to 12m has numerous coral bommies which provide shelter for angelfish, spotted sweetlips, groupers and rays. From 12-16m you find the reef increasingly taken over by staghorn coral and a corresponding abundance of vivid smaller fish.

  • Sting Ray Alley
    There is a huge amount of sting rays to be seen here as its name suggests, both during the day and especially on a night-dive. This is a rocky site which harbours a wide variety of marine life such octopus, scorpionfish, cuttlefish and crustaceans. As you dive further out into the bay, there are small off-shore reefs as you go below 25m.

  • The Steps
    This site gets its name from the rock formation under the water: nearer the shore there is a large shallow ledge at around 3-4m, then it steps down to around 7m, then again to around 10m to the sand at 12m. The large flat steps are covered in hard corals, usually with excellent visibility. Deeper, there are bright coral bommies and an array of stunning hard corals. Look for the juvenile spotted sweetlips waggling in and out of the urchins here.

  • Beady-Eye Bay
    Named by one of our fun divers, this site is great for night diving - in particular for the large assortment of crustaceans with red beady eyes that seem to be watching you where ever you go! You can also find squid, cuttlefish, pufferfish, rays and moray eels in this sheltered shallow bay.

  • Fly By Reef
    As its name indicates, this site has a current and is often a spine-tingling drift dive. The reef extends over rocks from the shore with the best corals at around 12m and a diversity of marine life. As you "fly by" the reef it deepens further out to 20m+, usually with excellent visibility.

    Koh Rong Saloem is situated around 1 1/2-2 hours from the mainland and south of Koh Kon, but is a much bigger island comprising 3 major beaches and several other minor ones. There is one small fishing village at the very north end with around 25 huts, and a few other small huts dotted around the island, but it remains little visited and provides perfect secluded beaches and exclusive diving. Visibility ranges from 5-25m but is usually around 10m.

  • Cobia Point
    As it's name suggests, this place tends to attract a lot of cobia (kingfish). These are large fish up to 2m long and resemble grey reef sharks. Although they're non-harmful, they are very curious and often hang around the divers for much of the dive, which can be a bit unnerving if you don't know what they are! Stunning corals line the cliff face here which plunges quite steeply from the shore to around 18m. The site itself often has a current and is usually a drift dive.

  • Rocky Bay
    This is a more sheltered site ideal for taking your time to look closely at the corals and abundant fish life. As the maximum depth is around 10m, you're able to get a nice long dive. This is a great site for macro-life with many nudibranch, crustaceans and juvenile fish.

  • Nudibranch Heaven
    Unsuprisingly, this dive site features many different types of nudibranch. Again, a fairly shallow dive site, the reef gradually falling from the shore to a max of 10m, this site shelters many cuttlefish, pufferfish, moray eels and small octopus. Several types of rays are often to be found here as well as schools of damsel and parrot fish.

  • Sponge Garden
    This site is named after the many large barrel sponges which abound along the reef here. Inside the sponges you can find scorpionfish, lion fish and many shrimp and crabs. The reef drops from the shoreline to around 10m closer to the beach and extends to 17m further out. We find cobia here too as well as barracuda. There are schools of yellow goatfish and parrotfish , which are often so thick it's like a wall of fish blocking the view of the brightly coloured reef.

  • Two Tone Garden
    As it's name implies, this site almost splits into 2 different dive experiences. The first diving closer to shore is characterized by reef to around 12m with many large coral bommies and formations and an abundance of fish life. As you drift further out the reef becomes more shallow and gives way to great pink fields of anemones and whip coral, usually with amazing visibility. This is a great night dive site with blue-spotted sting rays, scorpionfish and many marine worms and crustaceans.

  • Victoria's Secret Garden
    A well-hidden site and easy to miss, this is a narrow strip of off-shore reef which runs along at about a 10m depth. The site itself often has a mild current and is usually a drift dive. It sports stunning soft corals and well as a profusion of brilliant marine life.

    Koh Kon is a small uninhabited island about 1 1/2-2 hours from the mainland. It has two tiny beaches on the east side, the rest being rock that goes down to the sea. The best diving around this island is to the west and south. Visibility ranges from 5-25m but is usually around 10m.

  • Koh Kon West - 2 Bays
    This dive site is characterized by rocks at the water's edge which drop off, gradually at the south end and sharply further north, to a sandy bottom at around 16m. From the shallows, there is a proliferation of dazzling coral and fish life. At the south end there are many anemones, box fish, large parrot fish and schools of yellow goat fish. Further north at around 12m there are sea bass and large snappers and sweetlips.

  • Koh Kon South
    This dive site has coral reef from the shore which drops to a shallow sandy bottom at around 9m and gradually goes deeper to the west to a maximum of 14m. Again there are many brilliant anemones and an abundance of fish life. This is a great spot for a night dive with electric blue-spotted stingrays mingling with moray eels, and bamboo and cat sharks.
