Main image

Formigas is a cluster of small rocky islets and reefs in the Azores Atlantic archipelago, notable as a marine hazard and for its surrounding seabed habitats. The outcrops are marked for navigation and are visited by diving operators from nearby islands for underwater interest.

The area supports diverse marine life on the reef and attracts seabirds to the rock outcrops. Access is by boat and conditions can be rough; visits are generally limited and dictated by sea state.

Historically the rocks have been a known navigational feature for mariners in the Azores and later marked by beacons and navigation aids. The group lies offshore within Azorean maritime waters and is managed as part of the region’s coastal and marine environment.

The islets sit in the Atlantic Ocean as part of the Azores autonomous region of Portugal, well offshore from the main inhabited islands and reached only by sea.
