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.

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.
Geology here is blunt and volcanic: hardened lava domes and eroded tuff create caves, natural windows and the famous collapsed chamber known as Hidden Beach. The islands were long altered by human use — once a military practice site — and today are protected as a national park with strict visitor limits to preserve nesting seabirds and coral shelves. Locals from Puerto Vallarta and Punta de Mita have long respected these rocks for fishing and as seasonal whale-watching grounds.
Expect guided snorkeling over rocky reefs where tropical fish, occasional green sea turtles and ray shadows appear with the current. Hidden Beach visits are scheduled and limited — you’ll typically have about 20–25 minutes inside the protected sand bowl, and entry depends on tide and sea state. The operator supplies masks, fins and a refill station; the park operates a plastic-free policy.
Practical edge: arrive with ID, a refillable bottle, reef-safe sunscreen and a lightweight top for sun and chop. If you get seasick, take medication before boarding. The walk through the cave to the beach requires a short swim or wade and basic comfort in open water — not technical, but not passive sightseeing either. Tours run around four hours; plan half a day and leave time for transit back to Puerto Vallarta or Punta de Mita.
Hidden Beach access is guaranteed for guests who select that option, except when conditions (tide, swell, or weather) make entry unsafe — operators will prioritize safety and national park rules.
Minimum recommended age for Hidden Beach is 10 with an accompanying adult; the tour is not recommended for pregnant guests or people with serious spinal or cardiovascular conditions.
No — snorkel masks, fins and brief orientation are provided; you may bring your own fitted mask if you prefer.
Operators typically offer a full refund or rescheduling if they cancel due to weather or unsafe sea conditions; check the provider’s 24-hour cancellation window for refunds.
