A 2–2.5 hour catamaran from Portimão takes you along dramatic limestone cliffs to the Benagil sea cave, with swimming at Praia da Marinha and views of traditional Algarvian villages. Accessible, family-friendly, and timed to show off the cave’s skylight.

The catamaran slips away from Portimão Marina just after a low, polite swell nudges the hull—sunlight catches the whitehouses on the river and the Algarve cliffs stand like pages torn from a map. Within minutes the shoreline unfolds: little harbors, chalky ledges, and the first of the caves—arches carved by a patient Atlantic that seems intent on rearranging the coast. Onboard, the guide points out the striations in the rock and the weathered villages that watch the sea like old harbor masters.
