Arrábida Natural Park

Arrábida Natural Park is a protected area in Portugal. Founded in 1976, the park occupies an area of 176.41 km2 (68.11 sq mi), (123.30 km2 (47.61 sq mi) on land and 53.11 km2 (20.51 sq mi) at sea, covering the southernmost margin of the Setúbal Peninsula. One of the park's unique features is its carbonate geology mountain range, Serra da Arrábida (501 metres (1,644 ft)) which comes into contact with the ocean similarly to some locations in the Mediterranean, contrasting with the usual Portuguese coast (long sand beaches and cliffs)

Three of the park's beaches—Galapinhos, Portinho da Arrábida and Figueirinha—are popular among the inhabitants of Lisbon and Setúbal. Overlooking the three beaches is the Convent of Our Lady of Arrábida, a former monastery established in the 16th century, managed today by the Fundação Oriente.
