Diving Cambodia’s uncharted waters is a colourful experience, all the better for the lack of other divers. In places visibility reaches up to 20m, and, with a wealth of islands to choose from, operators can offer itineraries ranging from reefs encased in coral to an almost overabundance of marine life, including barracuda, puffer fish, moray eels, giant mussels and parrot fish. Closest to Sihanoukville at just two hours away, Koh Rong Samloem is the most popular day-excursion; trips include a couple of dives, a lazy lunch and a spot of beachcombing on its gloriously white sands. You could also stay overnight. Further afield, more experienced divers might prefer overnight trips to Koh Tang and Koh Prins (each a 5–7hr boat ride away), with reefs, coral bommies, a wreck or two and better visibility in their deeper waters.
