Poilão is a tiny, uninhabited island in the far south of the Bijagós Archipelago and represents one of the most significant marine nature reserves in the world. The island is the heart of the João-Vieira-Poilão National Park and is considered the most important nesting site for the green sea turtle (Chelonia mydas) along the entire African Atlantic coast. The nature on Poilão is completely pristine; the beaches consist of fine coral sand and are surrounded by a narrow belt of coastal forest. Because the island is considered sacred to the Bijagó people, it is permanently uninhabited, providing turtles with an undisturbed space for their reproductive cycles. Tens of thousands of females come here annually to lay their eggs. The waters around the island are part of a strictly protected marine core area where fishing is prohibited, leading to an extraordinary density of marine life. Poilão is a symbol of the successful connection between indigenous belief and modern nature conservation. The island is also a critical resting place for rare seabirds. Access is extremely restricted for ecological and spiritual reasons, making Poilão one of the most exclusive refuges for marine biodiversity in West Africa.

📋 Practical info
Getting there
The island is typically reached by a specialized boat trip from Bubaque or other major Bijagós islands, usually organized through experienced local operators. The sea journey generally takes several hours depending on prevailing tides and weather.
Best season
The most appropriate time to visit is typically during the dry season, particularly when the sea turtles are actively nesting, though exact timing can vary. It is highly advisable to avoid the heavy tropical rainy season.
Terrain & paths
The landscape primarily consists of sandy coastal beaches where turtles nest, surrounded by dense tropical vegetation. Visitors should expect uneven, entirely natural ground with virtually no modern infrastructure.
What to bring
Ensure you bring strong sun protection, effective insect repellent, adequate drinking water, and culturally respectful clothing. Binoculars are highly recommended for observing the incredible wildlife without causing any disturbance.
Parking

Safety
It is crucial to follow local guides strictly to avoid disturbing the sacred cultural sites and fragile turtle nests. Be prepared for intense sun exposure and ensure your chosen boat operator is thoroughly reputable.
