One of 23 islands in the sea of Koh Kong, Koh Kmoch (Ghost Island) has a wealth of corals and other sealife visible through its crystal clear water.

It is located off Kiri Sakor District, and is part of 36,000-hectares being developed by the Chinese Union Development Group, who plan to build an airport, a port, a golf course and ecotourism resorts on the islands in this area over the next 25 years.
