Marietas Islands Snorkeling & Hidden Beach Tour from Puerto Vallarta
A small-boat snorkeling trip to the Marietas Islands that balances wildlife encounters and geology with strict park rules. Expect clear water, strong currents, and a chance—if quotas allow—to visit the famous Hidden Beach.
The Experience
Before You Go
Morning departures are calmer
Choose the earliest boat possible for the best underwater visibility and gentler seas.
Bring reef-safe sunscreen
Regular sunscreen harms coral—use reef-safe lotion and reapply before boarding to minimize contact with water.
Be ready for ladder entry
You must climb a ladder into the surf to board and disembark; wear secure footwear and be confident handling waves.
Hidden Beach access is limited
Park quotas and tides limit entry—if you don’t get a slot, accept the on-board raffle and enjoy snorkel time instead.
Local Knowledge
Hidden Gems
- •Snorkel the outer fringe reef on the island’s northwest side for denser coral patches
- •Watch for boobies on the rocky ledges at the islets’ lee side in late morning when birds return from fishing
Wildlife
- •Blue-footed booby
- •Sea turtle (green or hawksbill occasionally)
Conservation Note
Visitor numbers are tightly controlled and drones are banned; use reef-safe sunscreen, avoid touching wildlife or coral, and follow guides’ instructions to minimize impact.
The Marietas were once used for military target practice, which helped form some caves; the area is now a protected national park under CONANP to conserve seabird colonies and reef habitat.

Common Questions
How likely is it to enter the Hidden Beach?
Entry depends on CONANP quotas, tides, weather, and group size; operators use a raffle when spots are limited—plan for a chance but not a guarantee.
Is snorkeling gear provided?
Yes—mask, snorkel, and fins are provided, though many travelers bring a well-fitted personal mask for comfort.
Can non-swimmers join the tour?
No—the trip requires basic swim ability and comfort entering and exiting via ladder; non-swimmers should not attempt this tour.
Are children allowed on the Hidden Beach?
Park rules set age limits for beach access (usually 10 to 65); children younger than that can stay on board under crew supervision.
Are meals included?
The trip includes bottled water and a box lunch (sandwich, granola bar, fruit); bring extra snacks if you have specific dietary needs.
What should I do about seasickness?
Take preventative medication the night before or a couple hours before departure; choose the front of the boat for a steadier ride and stay hydrated.
