Best Season
November through April is the strongest season for added wildlife interest, especially humpback whales in the bay. Outside whale season, trips still run when weather and park operations allow.

Safety & Access At Islas Marietas
Hazards, restrictions, and access requirements.
Key Hazards
Restricted access
Safety Notes
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.
Access Restrictions
Access is by authorized boat tour within the protected Islas Marietas area. Sensitive zones can have quotas or schedule limits, and the park closes on Mondays and Tuesdays.
Legal Notes
Islas Marietas is a protected national park and UNESCO biosphere reserve area. Follow guide instructions, stay within authorized visitor zones, and expect tighter controls around sensitive areas such as Playa Escondida.

Community notes to help plan your visit.
Scuba
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.
Snorkel
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.
