THE LANDSCAPE

Hidden Bays and Limestone Cliffs

Praia do Portinho da Arrábida and the cluster of coves nearby—white sand, clear water and the notable Pedra da Anicha—define the park’s coastal scenery and marine biodiversity that you swim through and beside.

THE ROUTE

A Linear Open-Water Swim from Alpertuche to Galapinhos

The route launches from Alpertuche Beach and follows the coast to Galapinhos, keeping swimmers close to sandy stretches and scattered rocks for a continuous, scenic crossing of roughly 3–5 km.

THE WILDLIFE

Boat Return with Dolphin-Spotting Chances

After the swim the group returns by boat to Sesimbra, with a high probability of encountering dolphins during the trip back along the coast.
