A guided, half-day open-water swim from Sesimbra that navigates natural crevices and arches along Praia da Baleeira, useful for planning logistics and what to expect.
Beneath the Cliffs: A Half-Day Swim Through Cabo Espichel’s Secret Passages.
This half-day open-water swim out of Sesimbra takes you to Praia da Baleeira, a pebble beach tucked beneath the steep slopes of Cabo Espichel. Guided by experienced leaders with boat support, the route threads beneath a named crevice and through the Arco da Pombeira, passes dense seaweed forests sheltering local fish, and can finish with the support boat waiting at Chã dos Navegantes — on occasion the return trip is accompanied by dolphins.

Praia da Baleeira: a pebble cove beneath sheer cliffs
A small pebble beach sheltered by the slopes of Cabo Espichel and by Forte S. Domingos da Baralha, Praia da Baleeira is the starting point for a swim that feels carved into the coastline.
Crevices and arches: Ponta da Passagem to Arco da Pombeira
The swim begins at Ponta da Passagem beneath the crevice that names the place and continues through the imposing natural arch of Arco da Pombeira—the route’s high point and a defining landmark of the tour.
Seaweed forests, coastal fish and the chance of dolphins
Along the entire route dense forests of seaweed provide refuge for marine life; swimmers may spot shoals of bream and salemas, and the return by boat is sometimes accompanied by dolphins.
