A turquoise rim of ocean breaks against weathered volcanic rock as the boat eases toward the Marietas Islands. Salt spray and gull calls frame the first glimpse of collapsed caves and steep, dark cliffs where blue-footed boobies promenade; the guide readies masks and points to a pale sweep of sand—Playa Nopalera—visible only at certain tides. For three hours the trip moves like a slow reconnaissance: snorkeling coral gardens, peering into sea caves, and circling islets with nesting birds.
