Join our marine biologist and naturalist guides as they share insights about the islands' ecosystem, marine life, seabirds, and conservation efforts. Travel aboard a comfortable, safe, and fast boat in a small group of no more than 10 guests for a more personal experience.
Hidden Beach access is regulated by the Mexican government and depends on permits, weather, ocean conditions, swimming ability, and age restrictions. Only 116 visitors per day are allowed, so access cannot be guaranteed. If conditions allow, your guide will take you there at no additional cost.
Whether or not you visit Hidden Beach, this tour offers an unforgettable way to explore one of Puerto Vallarta's most extraordinary natural wonders.

It´s important for you to acknowledge that tour operators cannot guarantee the entrance to the Hidden Beach ahead of time. We do our best effort on every visit to get places for our tourists to enter, but it`s not always possible. If we don’t get spots for the entire group, we`ll do a bingo raffle on board in order to offer the same possibility to everybody on the trip. Visitors who don’t get a spot to enter (or that decide not to enter), have to stay on board our boat with the captain for approximately 30 minutes. Park regulations doesn´t allow to snorkel or swim in the Hidden Beach area. During this time, you can relax and enjoy the scenery and the magnificent birds that inhabit the islands.
All participants must be able to enter and leave the boat with the help of a ladder.
