Use a local operator, follow marine-park rules, and expect a full boat day rather than quick in-and-out diving. Conditions can change across the island group, so briefings on the selected sub-site matter.

Scuba Diving
Most scuba visits are guided boat dives around the island group rather than one fixed mooring. Expect volcanic structure, caverns, reef life, and wildlife-focused diving that depends on the day's selected sub-site.
Snorkeling
Snorkeling is a common way to visit Islas Marietas and is often paired with guided island tours. Surface conditions and protected-area rules determine where groups can enter the water.
