Access to Hidden Beach is limited to 116 visitors per day, making it one of the most exclusive and sought-after experiences in the region. As a certified tour operator with more official permits than most providers, Eco Explorer offers more available spots daily, giving you a higher chance of accessing the beach. In fact, 99% of our guests successfully visit Hidden Beach, with rare exceptions due to weather or natural conditions.
Our fast, comfortable, and safety-certified boats ensure a smooth ride, and our experienced guides support you every step of the way—from boarding the boat to the snorkeling experience, to the safe entry into Hidden Beach. Their knowledge and attention to detail provide an informative and memorable adventure.
Please note that Hidden Beach access is available Tue-Sun only. It cannot be added during booking but can be requested at check-in. Access is guaranteed for those who choose this option, except in cases of unfavorable weather or natural sea conditions.
Upon arrival, guests will check in and be warmly welcomed by their guide. The guide will provide all necessary snorkeling gear and ensure that everyone is fully prepared for the adventure. Once ready, the group will walk to the pier to board the boat and begin the scenic journey to the stunning Marietas Islands. At the islands, enjoy guided snorkeling in crystal-clear waters (weather permitting) and the chance to observe a wide variety of marine life and seabirds in this protected natural area. Please note that water clarity can vary depending on sea and weather conditions. For those who select the Hidden Beach access option, there may be a short wait before your scheduled time to swim through the cave entrance to reach this extraordinary and secluded beach. Once inside, you’ll have approximately 20–25 minutes to swim, relax, take photos, and enjoy the serenity of this world-famous natural wonder. As part of the park’s commitment to conservation, the Marietas Islands are a designated plastic-free zone. We kindly ask that you bring a refillable water bottle to stay hydrated. A water refill station and eco-friendly cups are also available on the boat for your convenience.
