Walk north from the lighthouse along the rocky foreshore at low tide and you cannot miss the corrales de pesca — long curved walls of black stone laid out across the intertidal zone. Each one is a giant fish trap: as the tide ebbs, fish stranded inside the wall are picked up by the corraleros wading through the shallow pools with hand nets.
The traps are still actively used, particularly the corrales of "El Hondón", "El Mortandad", and "La Reina". They are protected as Bienes de Interés Cultural. The best time to see them in use is on a low spring tide; check the tide tables and ask at the tourist office about the schedule of demonstration outings.
