Bijagos Archipelago off Bissau is a tidal island landscape of mangroves, mudflats and sandy edges. It includes 88 islands and islets, and UNESCO recognised the wider Bolama-Bijagos Biosphere Reserve in 1996.
Bijagos Archipelago and its tidal geography
The archipelago lies off the coast of Guinea-Bissau in West Africa, opposite the mouth of the Rio Geba. Its channels, flats and islands form a marine and intertidal system that changes with the tides.Bolama-Bijagos Biosphere Reserve
The islands are low-lying, with mangroves, palm groves, savannah and tropical forest across different parts of the group. The landscape is shaped by water, with broad stretches exposed at low tide and cut by channels between the islands.coastal and marine ecosystems
Island communities and protected status
Bijagós communities live across the archipelago, and island life remains tied to fishing, boat travel and the rhythm of the sea. The place is also known for the cultural traditions of the Bijagós people, who have long shaped life on the islands.
The archipelago was added to the UNESCO World Heritage List in 2025 as the Coastal and Marine Ecosystems of the Bijagós Archipelago. That designation sits alongside its earlier status as a biosphere reserve, and both names point to the same broad island system.
What stands out in the archipelago
What makes Bijagos Archipelago distinctive is the scale of open water, mudflat and mangrove threaded between the islands. The result is a place where land does not present itself as a single mass, but as a shifting chain of edges, channels and inlets.exceptional biodiversity
That coastal pattern gives the archipelago its character as much as the individual islands do. In broad terms, the islands, flats and waters belong together as one connected marine landscape rather than separate sights.
