Rio Cacheu Manatee Sanctuary (Guinea-Bissau)

Weather…

The Rio Cacheu Manatee Sanctuary in northern Guinea-Bissau is one of the most critical refuges for the West African Manatee (Trichechus senegalensis). These rare and elusive aquatic mammals have found good living conditions in the extensive mangrove swamps and brackish water areas of the Cacheu River. The region is characterized by a complex network of waterways, rich in the aquatic plants that form the manatees' primary diet. Protecting this species is a significant challenge, as they are threatened by illegal hunting and habitat loss. The sanctuary is part of the Rio Cacheu Mangrove National Park and serves as a center for scientific research and local awareness programs. Local communities are actively involved in conservation efforts, as the manatee plays a spiritual role in many regional legends. Visiting the sanctuary requires great patience, as the animals spend most of their time submerged, surfacing only briefly to breathe. Nevertheless, the site is an important hub for ecotourism, highlighting the importance of preserving mangrove ecosystems for the survival of West Africa's unique wildlife.

Etiquette
Do not approach manatees by boat; keep distance and turn off the engine. Avoid loud noises and do not feed the animals.

Binoculars with a polarizing filter help see below the water surface. Sunscreen, hat, and plenty of water are important for boat trips in tropical climate.
