Meals on liveaboard trips to the outer islands are provided aboard the vessel, typically featuring a mix of Khmer and international cuisine. Fresh seafood caught during the crossing is prepared with traditional Khmer spices. Breakfast, lunch, and dinner are included with tropical fruits, salads, and grilled dishes. Day trips to Koh Tang include packed lunches or catered meals on the dive boat. The remote offshore location means all meals must be arranged through the liveaboard operator or dive centre. Surface intervals between dives provide opportunities for communal dining and sharing observations about the remarkable pelagic encounters.

Koh Tang and the outer islands represent Cambodia's most advanced and adventurous diving, featuring eight world-class sites in the open waters of the Gulf of Thailand. Koh Tang Island is the diving centrepiece with The Steps offering a spectacular stepped reef from 5 to 40 metres with huge gorgonians and schooling barracuda, and the Big Drop-Off delivering Cambodia's premier wall dive with grey reef sharks, tuna, and occasional whale sharks. The Three Bears seamount attracts seasonal manta rays from February to May alongside massive snapper schools. The Mayaguez Wreck adds historical intrigue as the remains of the US container ship from the famous 1975 incident. Dolphin Reef regularly hosts spinner and bottlenose dolphins. Further offshore, Koh Prins (Prince Island) offers the Prins Pinnacle with dogtooth tuna and sailfish, and Prins Wall with whitetip sharks and giant trevally. Koh Poulo Wai, Cambodia's most remote diving destination, features untouched coral walls with shark schools, huge dogtooth tuna, manta ray cleaning stations, and spectacular visibility of 30 metres or more. These outer island sites are reached by 2 to 3 hour boat transfers from Sihanoukville and are often visited on multi-day liveaboard trips. The exposed offshore conditions create the best visibility and pelagic encounters in Cambodia.

Koh Tang & Outer Islands

Southwest monsoon bringing rougher seas, reduced visibility, and some dive sites may be inaccessible.

Koh Tang and the outer islands are reached by boat from Sihanoukville, approximately 2 to 3 hours offshore. The longer transfers require calm sea conditions during the dry season from November to April. Multi-day liveaboard trips are the preferred way to experience the outer islands, allowing divers to visit multiple sites including Koh Poulo Wai in a single trip. Day trips to Koh Tang are possible but involve significant time on the water. Weather-dependent scheduling is essential with flexible backup dates recommended.
