Cambodia Reef Conservation Project

Due to the completion of our work in Cambodia we will no longer be accepting volunteers for this site. Thank you to all of the hard working volunteers and staff who made this site such a success!

Cambodia is one of the most biodiverse countries in south-east Asia. Its coastline runs between Vietnam and Thailand and includes 69 different islands within the Gulf of Thailand. These islands are surrounded by coral reefs where divers can observe a wide range of underwater life including seahorses, nudibranchs and turtles. Working in some of the least researched habitats, CCC is helping the local government to set up Cambodia’s first large scale Marine Protected Area (MPA) in the Kompong Som region.

Project Aims

Coral Cay has been working in Cambodia since 2009 when it engaged in a two-year scientific survey programme to map the marine resources around the tropical islands of Koh Rong and Koh Rong Samloem in the Gulf of Thailand. With aid from the Blue Moon Fund and support from our in-country partners, the Fisheries Administration of the Royal Government of Cambodia (FiA), Fauna and Flora International (FFI), and other NGO’s, the work continues. CCC is currently monitoring the marine habitats of the islands and working closely with the FiA, FFI, local stakeholders, partners and the community, to assist in the implementation of Cambodia’s first well managed Marine Protected Area around the islands.

The MPA, at approximately 300km2 will feature a diverse range of habitats, including coral reefs, mangrove forests and seagrass beds, in addition to the upland rainforests found on both islands. The next step is to ensure a consensus is reached between all parties to create a successful zonation scheme allowing for conservation, recreation and sustainable fishing zones; in addition to encouraging the development of low impact tourism initiatives. CCC also works closely with the Royal University of Phnom Penh, giving marine ecology lectures and providing scholarship opportunities to the university’s students.

Volunteers : How will you help?

Joining us in Cambodia is a fantastic opportunity to contribute to the surveys crucial to the success of Cambodia’s first large scale MPA. You do not need to have any prior science or dive training as volunteers undergo a comprehensive training package, which will include a two week Skills Development Programme, and dive training (if applicable). Once you have successfully completed the training you will join a small team of staff, scholars and volunteers surveying the health of the coral reefs, and studying the beautiful microfauna of Cambodia’s seas.


Individuals booking on will need to be a minimum of 18 years of age but we are able to take on under 18’s if they join an expedition as part of a school or university group. We are also able to assist under/post graduate students who wish to conduct research projects in conjunction with their Coral Cay expedition. Please see here for more information. 

The Project Site

Coral Cay’s project site is located in Prek Svey a small coastal village untouched by tourism on the island of Koh Rong, 22km off the coast of Sihanoukville, southern Cambodia. This is our most rural site where you will be living in a house on stilts over the water, amongst the local fishing community. Living accommodation is dormitory style rooms with bunk beds or hammocks and volunteers can expect to live the ‘true research experience’ with limited electricity and no running water.
