Discover the stunning Marietas Islands with this private snorkeling tour from Puerto Vallarta, including guaranteed access to the famous Hidden Beach.

If you’re planning a trip to Puerto Vallarta and want to experience one of Mexico’s most unique natural wonders, this private tour to the Marietas Islands might just be the highlight of your visit. Known for its Hidden Beach, which is accessible only through a water cave, this tour combines snorkeling, scenic boat rides, and the thrill of visiting a protected marine sanctuary—all in a semi-private setting.
What we love most about this experience is the guaranteed access to Hidden Beach—a rare treat when many visitors struggle with limited daily permits—and the personalized nature of a private tour. It’s ideal if you’re seeking a more intimate, tailored adventure rather than a crowded group outing. The inclusion of snorkeling gear, snacks, and eco-conscious practices shows that this tour prioritizes comfort and conservation.
On the flip side, it’s important to note the cost—$552.50 for your group—which might seem steep at first glance, especially considering the entrance fee to Hidden Beach isn’t included. If budget is a concern, you’ll want to weigh that against the exclusivity and quality of experience. This trip suits travelers who value a more personalized, scenic, and eco-friendly adventure, especially those with a moderate physical fitness level who are comfortable on a boat and in the water.

For underwater exploration, these Puerto Vallarta snorkeling spots offer different experiences
Your adventure kicks off at the Tours Eco Explorer Vallarta office in Marina Vallarta, where you’ll check in and be greeted warmly by your guide. Arriving at 9:00 am, you’ll find yourself ready for a half-day of exploration. The meeting point is conveniently close to public transport, making it easy to reach.
Once checked in, your guide will outfit you with snorkeling equipment and run through safety tips. Expect a friendly briefing about the marine environment and the rules of the park, which is committed to plastic-free practices. Bring along a refillable water bottle — water refill stations are on board.
After boarding your private boat, you’ll set out on a scenic cruise across calm waters toward the Marietas Islands. The boat ride offers excellent views of Puerto Vallarta’s coast and a chance to spot seabirds and perhaps even whales, if in season. The trip takes roughly an hour, giving you ample time to relax, chat, and soak in the scenery.
For a more personal experience, these private Puerto Vallarta tours deliver individual attention
Once at the islands, your guide will help you gear up for guided snorkeling. The waters are usually crystal-clear, though water clarity can vary with weather — always a reminder that nature isn’t predictable. You’ll have the chance to see a variety of marine life, from colorful fish to possibly some sea stars, depending on conditions.
The main event is the Hidden Beach—an iconic natural cavity only reachable by swimming through a water-filled cave. Your guide will coordinate a short wait if needed, as access is limited to a certain number of visitors per day. Once inside, you’ll have about 20–25 minutes to swim, relax, or take photos in this secluded paradise.
As one reviewer noted, “If you stay calm, breast stroke in, and follow your guides instructions you will be fine. It only takes seconds to clear the lowest point and then your clear as the cave opens up.” That’s a good tip for anyone worried about the cave swim — it’s short and manageable with a little caution.
Aside from the beach, you’ll enjoy guided snorkeling around the islands, observing seabirds and marine life in their natural habitat. The park’s regulations ensure a pristine environment, and the boat includes eco-friendly features like a conservancy donation to Bahia Unida and permits for the national park.
After your time at Hidden Beach, the boat will return you to Marina Vallarta, usually by early afternoon. Throughout the trip, snacks like apples, bananas, and a sandwich are available, keeping your energy up.

While the cost of $552.50 might seem high, it includes many elements that add value: private boat, snorkeling gear, park permits, eco donations, and snacks. The guaranteed access to Hidden Beach makes this tour stand out, especially in a place where permits are limited and lines can be long.
One happy customer shared, “My family most enjoyed the adventure into the Hidden Beach. If you stay calm, breast stroke in, and follow your guides instructions you will be fine. It only takes seconds to clear the lowest point and then your clear as the cave opens up.” Such feedback emphasizes that the experience, while adventurous, is manageable with proper guidance.
This private tour is perfect for families with children over 10, couples seeking an intimate experience, or small groups wanting personalized attention. It’s especially suitable if you’re interested in a combination of snorkeling, scenic boat rides, and visiting a world-famous beach that’s tough to access without a guide.

If you’re after a unique, personalized adventure that combines snorkeling, scenic views, and access to one of Mexico’s most photographed beaches, this private tour offers excellent value. The small-group feel ensures you’ll get attentive service, making it a great choice for families, couples, or small groups who want an intimate experience.
The inclusion of eco-friendly practices and a focus on conservation add to the appeal, letting you enjoy a beautiful natural environment responsibly. The scenic boat ride, combined with the thrill of swimming into the cave to reach the Hidden Beach, makes this a memorable outing.
While the price isn’t cheap, the exclusivity, guaranteed access, and quality of the experience justify the investment for those who prioritize comfort, environmental responsibility, and authentic adventure. It’s an excellent way to see the Marietas Islands without the crowds and with the reassurance of a well-organized, professional guide.
