One of the Algarve's – and Portugal's – most emblematic sights, this huge natural seaside cave has a hole in its ceiling through which streaming sunlit illuminates the sandstone and beach below. The only way to access the interior is via the water. Numerous companies along the coast, such as Taruga Tours, run boat trips, and hire kayaks and SUPs (stand-up paddleboads) to paddle here yourself. Swimming to the caves is discouraged due to strong tides and currents, and high watercraft traffic.
From the cliffs above, you can look down to see the hole in the cave's roof.
