Set off from Portimão for a 2–3 hour catamaran that threads the Algarve’s dramatic cliffs to the light-washed mouth of Benagil Cave and the golden arches of Praia da Marinha. Expect narrated geology, a swim stop in protected water and some of Portugal’s most photogenic coastline.

You step aboard at Kiosk 5 in Marina de Portimão as the harbor yawns open to the Atlantic. The catamaran slips past low piers and fishing boats, the engine a steady pulse beneath the gulls' calls. Within minutes the town falls away and the coastline unspools—honey-colored cliffs, sculpted arches, and slim beaches that the sea keeps polishing. The guide points ahead: a round halo of light rimming the mouth of Benagil Cave, where sunlight funnels like a spotlight into a room cut entirely by waves.
