Deserta Grande Viewpoint

The Viewpoint is located at an altitude of 480 metres and since 1990 has been included in the Desertas Islands Nature Reserve. These islands are an important refuge for the monk seal, a species that currently has just over 25 individuals, as opposed to the 6 to 8 that existed in 1988, before the reserve was created. The bird life includes several colonies of sea birds such as the Cory's Shearwater, the Bulwer's Petrel, the Madeiran Storm Petrel and the extremely rare Fea’s Petrel.

As for the invertebrates, the Desertas Wolf Spider has a particularly important role, being an indigenous species restricted to the Castanheira Valley in Deserta Grande.
