EntryVaries

The Tristao Islands, named after the 15th-century Portuguese explorer Nuno Tristão, lie in Guinea's Boké region on the border with Guinea-Bissau, a group formed by the delta of the Kogon river out of sandbanks, mudflats, rocks, estuaries and mangrove forest; the main islands are Katarak, Kamsak, Kapken, Niémé, Souri and Foré Souri, and the largest, Tristan, is given an area of 226 km² (87 sq mi), a figure other sources apply to the whole group. Nalu and Balanta people live here from farming, fishing and fish smoking, palm oil, salt, livestock, shellfish, trade and crafts, while sea turtles, manatees, crocodiles and sharks share the surrounding waters. The islands were listed as a Ramsar wetland of international importance in 1992 and became a community marine protected area in 2008.
