At the southwest point of the promontory, this lighthouse overlooks the jagged volcanic reefs of the Arrecife de las Sirenas (Reef of the Mermaids), named after the monk seals that used to lounge here. The view into the water is fantastically clear. A side road runs 3km up to the Torre Vigía Vela Blanca , an 18th-century watchtower with wonderful views in both directions along the coast.
From the Torre the road is blocked to motor vehicles, but walkers and cyclists can continue 5km down to Playa de Mónsul and, beyond that, San José.
