Bijagos Archipelago and its tidal islands

Bijagos Archipelago lies off Bissau in Guinea-Bissau, where Atlantic water meets a web of islands, mudflats and mangroves. It is an archipelago shaped by tides and recognised for the scale of its marine landscape.

Bijagos Archipelago and its island landscape

The archipelago includes 88 islands and islets, spread across shallow coastal waters. The name usually appears beside Bolama-Bijagós in formal designations, and the territory has long been treated as a distinct island world within Guinea-Bissau.World Heritage property

Mangroves, sandbanks and intertidal flats define much of the scene, with water and land interlacing across large stretches of coast. The archipelago reaches into the estuary system opposite the mouth of the Rio Geba, giving it a maritime character that differs sharply from the mainland around Bissau.ancient delta of the Rio Geba

Bolama, Bubaque and the wider coastal setting

Bolama and Bubaque are among the best-known island names associated with the archipelago, which is spread across a broad coastal zone rather than a single compact group. The wider setting belongs to a landscape of tidal channels, low shorelines and saltwater edges that have shaped settlement patterns over generations.

The archipelago has also carried biosphere reserve status since 1996, a designation that sits alongside its later World Heritage inscription. Those formal labels place it among West Africa’s most closely watched coastal ecosystems and underline its significance as a natural and cultural landscape.biosphere reserve statusinscribed in 2025

Marine life, birds and protected status

Coastal and marine ecosystems cover the most visible part of the archipelago’s recent World Heritage inscription. The area includes mangroves, intertidal habitats and habitats linked to fish, reptiles, birds and marine mammals, giving the islands a layered ecological profile rather than a single scenic feature.coastal and marine ecosystems

The archipelago is also associated with formal wetland protection under Ramsar as Archipel Bolama-Bijagós. That status reflects the scale of its tidal flats, mangroves and offshore waters, and it adds another recognised frame for understanding the islands beyond their immediate shoreline.Archipel Bolama-Bijagós
