About Bijagos

The Bijagós archipelago is a sensitive cultural and ecological landscape, not a generic tropical-island escape. Boat journeys, mangroves, beaches, traditional communities, birdlife, turtles, and protected areas depend on tides, weather, local permissions, and a small number of reliable operators. Some islands and sites have spiritual or community restrictions that visitors must follow. Arrange guides, permits, food, fuel, and accommodation before departure, carry communication and medical essentials, never approach wildlife or sacred areas casually, and allow several spare days around every mainland or inter-island transfer.
