Discover the beauty of Marietas Islands with this small-group snorkeling tour, exploring Playa Nopalera, the Bufadora, and more for an authentic experience.
Planning a trip to Puerto Vallarta? If you’re craving a mix of stunning scenery, wildlife, and underwater exploration, the Basic Marietas Islands Tour offered by Grimar Adventures could be just what you need. This tour promises an intimate experience, focusing on iconic spots like Playa Nopalera, the Bufadora, and the famous Marietas Islands without the crowds of the hidden beach. Based on numerous traveler reviews and the detailed itinerary, we’ll give you a balanced look at what makes this trip stand out—and what potential travelers should consider.
What We Love About This Tour:
First, the focus on small groups—with only eight passengers per boat—really makes a difference for comfort and personalized attention. It’s clear the guides prioritize a relaxed, friendly atmosphere.
Second, the variety packed into just 2.5 hours—snorkeling, spotting birds, marveling at natural rock formations, and visiting Playa Nopalera—offers a well-rounded, authentic slice of the islands’ natural charm.
A possible consideration is that entrance to the hidden beach of love isn’t included—if that’s your main goal, you’ll need to book a separate trip. Also, since it’s a shorter tour, it might not satisfy those wanting a full-day or more immersive experience.
This tour is perfect for travelers who want a manageable, value-packed half-day adventure that combines snorkeling, wildlife, and beautiful scenery without feeling rushed. It’s especially suited for those who appreciate a small-group vibe and authentic local insights.

For underwater exploration, these Puerto Vallarta snorkeling spots offer different experiences
Starting with the booking process, this tour keeps groups small—no more than eight travelers per boat—which is a big plus for those who dislike large, noisy tour groups. If more friends or family want to join, the operator can split you into multiple boats, ensuring everyone receives personal attention. This smaller size encourages more interaction with guides and a more relaxed atmosphere.
The tour kicks off at Grimar Adventures’ meeting point on Av. Las Pangas in Corral del Risco. From there, a private boat whisks you out to the islands, with a total duration of about 2.5 hours.
First stop: Marietas Islands. Here, the highlight is the Puente de Piedra (Stone Bridge)—a natural arch that’s perfect for photos. We loved the way guides shared fascinating facts about the geology and wildlife of the area, making the experience both fun and educational. Snorkeling is a big part of this stop; you’ll swim among colorful fish in clear waters for about 25-30 minutes. Reviewers note that water clarity can vary, with some mentioning that it was “a bit murky,” but overall, most found the snorkeling worthwhile.
Next, Playa Nopalera. This quieter beach offers a chance to walk, swim, or explore caves. Travelers can take photos, relax, or dip into the calm waters. The reviews mention that guides are helpful and informative here, making sure everyone gets the most out of their visit.
The Bufadora, a natural spouting rock, is another highlight. Travelers enjoy witnessing this natural spectacle, where pressurized water shoots out with each wave—a fun and unique sight.
Wildlife and natural features round out the trip. Birdwatchers will love spotting the Blue-legged Booby Birds, and the various arches and caves provide excellent photo opportunities. The guides’ knowledge about the local flora and fauna adds to the experience, making it more than just sightseeing.
All snorkeling gear and lifejackets are provided, along with waterproof bags to protect your electronics. Non-alcoholic beverages keep you refreshed, and transportation is handled via private boat, which adds a level of comfort and convenience.
Since the tour doesn’t include entry to the Hidden Beach (Beach of Love), if that’s your main goal, you might want a different tour. Food is also not provided, so plan to bring snacks or eat before your trip.
Reviewers consistently praise guides Johnny, Jesus, and Reuben for their friendliness and knowledge. They’re attentive and eager to share insights into the islands’ geology, wildlife, and history. That personal touch makes the smaller group feel more like a friendly outing than a commercial excursion.
At just under 3 hours, this tour is a light yet fulfilling adventure—perfect for those with limited time or looking for a quick escape from city life. The price of approximately $67 includes snorkeling equipment, lifejackets, and transport, which collectively offer good value.
The tour is weather-dependent—poor conditions mean possible cancellation or rescheduling. The operator offers a full refund if canceled more than 24 hours in advance, providing peace of mind for spontaneous travelers.

From reviews, it’s clear that many guests leave feeling satisfied with the guides’ expertise and the natural beauty they’ve experienced. One reviewer mentioned, “The guides were excellent and very friendly,” while another appreciated the opportunity to see whales—a bonus not always promised but certainly appreciated.
Some travelers, however, note that water clarity may vary, so don’t expect crystal-clear visibility every time. Nevertheless, the overall quality of the snorkeling and scenery makes it worthwhile.

This experience is ideal for families, couples, or solo travelers who want a manageable, affordable introduction to the Marietas Islands’ natural splendors. It’s perfect for those who prefer small groups over large tours, and for anyone eager to snorkel, see birdlife, and explore caves without committing to a full-day adventure.
If you’re looking for a relaxed, well-organized trip that balances wildlife, scenery, and some underwater fun, this tour hits the mark. It’s especially appealing if you’re interested in a local-guided experience that values authentic encounters over commercialized attractions.

This tour combines professional guides, a small-group setting, and a carefully curated itinerary that showcases the best of what the Marietas Islands have to offer. The price point is reasonable, especially considering the snorkeling gear, private transportation, and the variety of sights packed into just a few hours.
While it doesn’t include entry to the popular Hidden Beach, it compensates with the chance to enjoy the islands’ natural beauty, caves, and wildlife at a relaxed pace. This makes it a great pick for travelers who want an authentic, less commercialized experience.
If you’re after a short, fun, and informative trip that feels personal and memorable, this tour deserves a spot on your Puerto Vallarta itinerary.
