The boat cuts through blue that deepens with each mile, spray spitting at your face as the Marietas rise from the Pacific like a sudden reef. Guides call out seabirds as the islands grow closer — their calls and the slap of the hull set the pace before you even take a breath and slip into the water.

4 hours
Fitness Level
Moderate fitness: able to swim short distances and climb in/out of the water; some brief walking over uneven surfaces.
Wildlife
History
The Marietas were formed by volcanic action and later altered by military target practice; the islands are now a protected national park to conserve seabird colonies and reef habitat.
Conservation
Visitor numbers are limited and the islands enforce a plastic-free rule and permit system—respect closures, avoid touching coral, and dispose of waste on the mainland.

Bring a refillable bottle
The Marietas are a plastic-free zone and boats provide refill stations; staying hydrated without single-use plastic is both required and convenient.
Use reef-safe sunscreen
Regular sunscreens harm coral — choose a reef-safe formula and apply before boarding to protect marine life.
Prepare for a short swim/wade
Hidden Beach requires a brief swim through a cave entrance; practice basic snorkeling and be comfortable in choppy water.
Take seasickness meds early
If you’re prone to motion sickness, take antiemetics before boarding — the approach can be bumpy depending on swell.
Reef-safe sunscreen
Protects your skin and the coral ecosystems that make the snorkeling worthwhile.
Water shoes or reef booties
Protect feet while boarding, wading and moving on rocky surfaces near the islands.
Refillable water bottle
Boat provides refills; single-use plastics are discouraged and often forbidden.
Light rash guard or swim top
Adds sun protection on the surface and a little warmth in cooler morning breezes.
