You step off the panga into warm Pacific water and the sea immediately sets the pace — a current that prods you toward a crescent of white sand cupped inside a collapsed cavern. The Marietas archipelago lies a short run from Puerto Vallarta, but the landscape here feels remote: volcanic rock carved by waves and time, cliffs punctured with caves, and a single famous inlet that rewards the patient swimmer.

Wear water shoes
Rocky landings and wet cave swims are easier with grippy, quick-dry footwear rather than bare feet or flip-flops.
