Berlenga Grande Island

Berlenga Grande Island is the main island of the Berlengas archipelago off the coast of Peniche, Portugal, and forms the heart of the Berlengas Nature Reserve. It is notable for steep cliffs, seabird colonies and a historic fort located on the island.

Visitors typically arrive by boat from Peniche to explore the fort, coastal caves and walking routes around the island; the shoreline and clear waters attract snorkelers and boaters. The island’s habitats are important for nesting seabirds and marine biodiversity, so access and activities are managed.

The fort on the island, constructed in the early modern era to defend the anchorage, is one of the principal historic structures and a common visitor destination. The reserve status has guided conservation and visitor management since its designation.

Berlenga Grande lies roughly off the western coast of Portugal near the town of Peniche, forming the largest landmass of the Berlengas group in the Atlantic.

• Protected reserve: The archipelago is protected as a nature reserve and marine area; landings and activities are regulated to protect seabirds and marine habitats.
