If you’re considering a trip to Puerto Vallarta and want to experience one of Mexico’s most iconic natural treasures, the Marietas Islands tour with guaranteed access to the hidden beach might be on your radar. This trip promises a mix of scenic boat rides, snorkeling, wildlife encounters, and an exclusive chance to step onto the famous beach of love, which is known for how tricky it can be to access without the right timing and guides.
What we really appreciate about this experience is the emphasis on small group sizes, limited to a maximum of 8 people per boat. It’s a big plus for anyone who prefers an intimate, less crowded adventure. Also, the guaranteed access to the hidden beach—a rare claim—can really take the stress out of planning, especially if that’s a key highlight of your trip to the islands.
That said, there are a few considerations you should keep in mind. This tour involves swimming about 100 meters to reach the hidden beach, which isn’t suitable for everyone. Plus, the tour’s success heavily depends on weather conditions—rough seas can make some activities more challenging or even prevent access to certain spots, like the hidden beach.
This tour seems best suited for travelers who love a bit of adventure, are comfortable in the water, and appreciate small-group, personalized experiences. If your goal is to see the iconic hidden beach with expert guidance, and you’re okay with some physical activity and variable weather, this could be a great fit.

What’s Included and What’s Not — Setting Expectations

For $164.42, this tour packs in quite a bit. The price covers all the essentials: life jackets, snorkeling gear, non-alcoholic beverages, waterproof bags, and most importantly, entry to the hidden beach. The transportation is by a covered boat, which keeps you dry and comfortable, even in a breezy sea.

The Itinerary — What You’ll See and Do
Stop 1: Marietas Islands and the Hidden Beach
The main event here is the guaranteed swim to the hidden beach, known as the Beach of Love. Access involves swimming roughly 100 meters through a cave tunnel—an exciting challenge that’s not for everyone. The tour guides are experienced and will assist you through this part, ensuring safety and support.
One review highlights the thrill of the swim: “While accessing the beach requires a strong swim through a cave with active currents, we enjoyed the thrill and felt very safe under Reuben’s watch.” For those with swimming skills and a sense of adventure, this can be one of the trip’s most memorable moments.
However, a couple of reviews note that weather conditions can impact the visibility and accessibility. For example, if seas are rough or jellyfish are plentiful—like one traveler experienced in May—the swim might be overshadowed by discomfort or inability to reach the beach. But the guides are flexible and will adjust plans accordingly.

Snorkeling and Wildlife Encounters

Some reviews mention “loads of different fish,” and others appreciated that the guides took the time to point out local wildlife, including Blue-legged Booby Birds and whales.
Scenic Stops: Bufadora and Playa Nopalera
Next, you’ll visit the famous Bufadora—a natural blowhole where seawater shoots up when waves hit it. It’s a powerful display of nature’s force, and many find it fascinating. You’ll also get to walk around or relax at Playa Nopalera, a beach with caves and photo opportunities.
A reviewer appreciated the flexibility here, saying, “We saw whales and had the option to snorkel or go to Cactus Beach,” showing the tour’s adaptability based on weather and conditions.
Photos and Beyond
The guides are friendly and knowledgeable, often taking photos of guests on the iconic stone bridge or at scenic spots. One traveler mentioned, “Ask your guide to take cool pictures,” which can be a good idea to capture memories without worrying about your phone in the water.
The Experience Quality and Guides

Multiple reviews praise the guides’ friendliness and knowledge—especially Ruben and Chuy—who are attentive to safety and eager to share interesting facts. They’re also quick to spot whales or dolphins, turning an already beautiful trip into a wildlife viewing adventure.
Value for Money
Considering the small groups, the variety of activities, and the access to the hidden beach, many guests feel the tour offers great value. It’s not just a boat ride; it’s a curated experience with expert guidance, which enhances safety and enjoyment.
Potential Downsides
The main concern for some is the weather and sea conditions, which can limit access or activity participation. For example, if the sea is too rough, the guides may not allow swimmers through the tunnel to the beach—disappointing if that was your main goal. Plus, some reviews mention difficulty in finding the meeting point, but most found it manageable with proper directions.
