Playa del Amor (Hidden Beach), Marietas Islands

Playa del Amor, a circular beach hidden inside a volcanic crater on the Marietas Islands, offers the most exclusive beach access in Mexico. Entry requires a permit-limited swim through a 33-foot tunnel only reachable by kayak from Puerto Vallarta. This strict regulation stems from its UNESCO Biosphere Reserve status, which caps daily visitors at just 116 people. The collapsed sea cave encloses the beach perfectly, creating a natural amphitheater of golden sand surrounded by lush cliffs. Swimmers enjoy calm, crystal-clear water year-round, with visibility averaging 40 feet. Adventurers must book permits months in advance, as demand exceeds supply by 80% during peak season.
