Península Valdés is a Patagonian nature reserve on the coast of Argentina. It’s known for the marine animals inhabiting its surrounding beaches and waters, such as whales, sea lions and elephant seals. On the peninsula’s west is the village and beach of Puerto Pirámides, once a salt-mining port. Beaches nearby include Los Molinos, with an abandoned windmill, and Las Cuevas, named after the caves in its low cliffs.
