Osmose is an NGO promoting alternative livelihoods , environmental education and social support. Osmose organises eco-tours in the UNESCO Biosphere Reserve of Prek Toal Core Area on the Tonle Sap Lake to make people discover the beautiful surroundings, the wildlife and the local communities.
Osmose has four different itineraries of one to two days with various activities such as the visit of the bird sanctuary, of the traditional floating villages, or of their projects. The 2 days itinerary also includes a night at the floating home stay with a certified guide. By participating to the eco-tours, visitors support the local villagers by providing them with income and funds to the community projects. The tours also enable to finance the environmental courses given to children of the village.
