In order to keep the Nature Reserve values, access to Berlenga Grande (the only island that can be visited) is controlled and limited. Help us keeping the islands biodiversity!

In Peniche pier:

- Regular liner service "Cabo Avelar Pessoa" during the bathing season (May to September); and

- some maritime-tourist boats provide access to the island throughout the year - make sure that they are properly licensed. Know which companies are recognized as nature tourism, referring to the National Register of Tourism Recreation agents.

It is considered that the Berlengas archipelago is the top of a horst, meaning a relief formed by blocks of the terrestrial crust elevated and limited by faults.

Berlenga Grande Island is a rounded plateau formed by a granite with medium to coarse grain biotite with some large crystals of orange potassium feldspar.
