A remarkable bird watching location, Prek Toal, Cambodia, OSMOSE

Take a tour on the great Tonle Sap Lake to watch the endangered bird species in Prek Toal Wildlife Sanctuary and experience traditional floating villages.

What to experience ?

Easily accessible from Siem Reap and featuring impressive water bird viewing, pristine flooded forests and traditional fishing and floating villages, Prek Toal Birdlife Sanctuary is an excursion that will be one of the highlights of your vacation in Cambodia.

Guided ecotours organised by Osmose to the villages of Prek Toal and Pech Kantiel give you the chance to see magnificent water birds, many of which are threatened.

You can visit the floating villages with paddlers from the village, and meet with the fish farm and floating garden owners to learn more of their unique way of life on the water. There are also opportunities to purchase locally produced water hyacinth handicrafts woven by the village women.

Osmose guides accompany every trip and all are bilingual (French, English, Chinese, or German); they are knowledgeable, fun, passionate and an invaluable part of the Osmose experience.

Choose a one-day tour taking you to see either Prek Toal or Peak Kanteil floating villages, exploring the bird sanctuary, and taking a village tour by traditional Khmer paddle boat. Or for a two-day tour enjoy the delights of experiencing life in a floating village plus a unique overnight stay in a community-based floating homestay.

How does it help?

Osmose is a non-profit organisation working in conservation, environmental education and sustainable development.

By choosing Osmose you will contribute to the community by directly supporting the village economy (paddlers, village tour, cooks, homestays, handicrafts), providing funds for Osmose’s various environmental education programmes to over 1200 children and their families, and for conservation.  Subjects include the importance of the forest in the life cycle of the fish on which the community depends for its livelihood, conservation of the forest flora and fauna, and responsible waste management, differentiating organic matter from inorganic.

Osmose helps in the development of three floating villages through the provision of children’s health clinics, providing food security by helping to build floating gardens, supplying canoes so families can fish, and building houses for the poorest families. Osmose has low overheads, so most of the funds it generates are directly put back into the projects they work with.

There are many ways in which Osmose has helped to contribute to the sustainable livelihoods of the people on the lake; revitalising the use of water hyacinth (thus reducing this invasive species), of weaving to promote handicrafts thus improving the lives of many women, as well as turning bird poachers into gamekeepers. Osmose employs more than 25 locals alone to protect the water bird colonies.
