Praia do Areia do Mastro

Portugal, Portugal

---

Praia do Areia do Mastro is a small, sheltered Atlantic beach near Cabo Espichel in the Sesimbra area of Setúbal, Portugal, set inside a rocky cove with pebbles and a narrow strip of sand that appears at low tide.

The shore sits at the base of ochre cliffs and rock formations, with clear rock pools and a vegetation-covered cliff top reached by a dirt path from the nearby hamlets, making the spot secluded and best reached on foot or by boat for swimming. The location is within the Arrábida natural region and is known for its scenic geology—sedimentary rock layers and pools popular with photographers—rather than for lifeguarded facilities or easy beach infrastructure.

Visitors should expect limited access, no formal services, and strong Atlantic conditions at times, so it’s suited to hikers, photographers, and people seeking a quiet, uncommercialized coastal cove.
