Discover the Small-Group Safari to Marietas Islands Including Hidden Beach

If you’re considering a trip to Puerto Vallarta and want to see some of the area’s most iconic sights, this small-group safari to the Marietas Islands could be just what you’re looking for. It promises a mix of adventure, wildlife, stunning scenery, and a handful of unique stops, all with a personal touch that larger tours often lack. With a solid 5.0-star rating from dozens of reviews, this tour has earned a reputation for being both memorable and well-organized.
What we love about this experience is how personalized it feels — less than 10 people in your group, meaning your guide can give you more attention and tailor your day a bit. The second is the variety packed into a 4 to 5-hour window, from swimming inside a volcanic crater to snorkeling, bird watching, and even whale spotting (during certain months). The only potential downside might be that some parts, like the Hidden Beach, depend on sea currents and tides, so timing can sometimes be a factor.
This tour is best suited for those who crave a full day of exploring nature’s wonders in a small, intimate setting. If you’re comfortable with swimming and don’t mind a physically active day, you’ll find plenty to love. It’s also ideal if you’re traveling with friends or family who enjoy a mix of adventure, wildlife observation, and delicious local food.

- Personalized Small Group: With fewer than 10 participants, your experience feels tailored and less rushed.

An In-Depth Look at the Marietas Islands Small-Group Safari

When you think about the Marietas Islands, what immediately comes to mind is the famous Hidden Beach — a stunning, secret paradise only accessible through a swim or a cave passage, depending on sea conditions. This tour offers a chance to visit that iconic spot, along with a host of other remarkable locations.
The Itinerary Breakdown
Start at Playa Escondida:
Your adventure kicks off with a crossing of approximately 80 meters through the marine tunnel. This swim, about 6-7 minutes round trip, is a highlight for many, offering a unique opportunity to enter the crater from beneath the surface. It’s an active start, and you’ll be wearing a life jacket, which makes it accessible to most swimmers, but be prepared that it can be a bit energetic. As some reviews note, timing depends on the tide, so the start might be delayed if conditions aren’t perfect. The guides keep you informed and safe, which helps ease any nerves.
Snorkeling in Calavera Reef:
Next, we hit the water to explore the Calavera Reef, where you’ll see marine life including the notable fish that grow their own food—an intriguing fact that guides often share. The snorkeling activity lasts around 35 minutes, giving you enough time to observe the vibrant underwater world. Since gear and life jackets are provided, you don’t need to bring your own unless you prefer. Many reviews highlight how excellent the snorkeling was, with one reviewer calling it “probably the best snorkeling I’ve experienced.”
Visiting Secret Beach:
This is the star of the tour for many — the Secret Beach. Thanks to changing sea currents, you might be able to visit it during your trip, even though it’s normally inaccessible most of the year. When open, it’s a secluded, postcard-worthy spot, perfect for relaxing or taking photos. The swim here is about 10 minutes, and the experience is described as “magical” by those who’ve been lucky enough to visit.
Second Crater & Stone Bridge:
Moving on, your boat will bring you close to the second crater, known as Stone Bridge or Puente de Piedra. Here, you get a brief but impressive view of the arch, which seems to suspend in time. It’s a peaceful spot, perfect for wishing or simply soaking in the scenery. The boat gets close enough for photos, and some reviews describe it as “an impressive natural formation.”
Bird Watching & Whale Watching:
The islands are a haven for seabirds, especially the Blue-footed Booby Bird, which many travelers find adorable and fascinating. During the right season (December to March), whale sightings are possible, especially with calves enjoying the sanctuary. Multiple reviews emphasize how noteworthy and exciting whale sightings have been, making this a seasonal highlight.
Sea Geyser & Geyser Excursion:
The Sea Geyser, or Blowhole, is an exciting spillover of the ocean’s energy, with jets of water shooting through the hole. It’s a quick stop but adds an element of drama to the trip. The guide’s commentary makes it even more engaging, explaining the natural phenomenon.
Gastronomic Experience & Optional Surf Lesson:
To wind down, your tour includes a delicious ceviche — made onsite with boiled shrimp, fruit juices, herbs, and fresh ingredients. It’s a tasty, refreshing way to end the adventure. For those interested in trying surfing, an optional 30-minute beginner lesson is available at an extra cost, on a friendly beach ideal for learning.
What We Think of the Tour Experience
Many reviews rave about the knowledgeable guides like Eduardo, who are praised for their friendliness, safety focus, and ability to share interesting facts about the environment. The small group size really enhances the experience — you’ll feel welcomed and not like just another face in a crowd.
The balance of activities is well thought out: you get to swim, snorkel, observe wildlife, and enjoy some scenic stops, all within a manageable timeframe. The inclusion of a lunch and drinks adds value, especially considering the fact that you’re exploring a marine protected area, where options can be limited.
Reviewers frequently mention how beautiful the water is — clear, warm, and perfect for swimming or snorkeling. Many describe the Hidden Beach as “magical,” and the fact that it’s only accessible a few months of the year makes the visit feel even more special.
Practical Details & Considerations
The tour lasts about 4 to 5 hours, starting at 9:00 am from Corral del Risco. The pickup involves a short boat ride, and the group size is capped at 10, which means more personalized attention. The price of $189.59 per person might seem high, but given the variety of activities, local guide expertise, and included meals, many find it worth the cost.
It’s important to note that moderate physical fitness is recommended, as you’ll be swimming and on your feet quite a bit. Children over 10 are welcomed, but younger kids might find some parts challenging. Also, the tour is weather-dependent — if seas are rough, some stops or activities might be postponed or canceled with a full refund offered if canceled.
What You’ll Love
You’ll appreciate the expert guidance and small group vibe, which makes the entire day feel special rather than rushed. The spectacular scenery, from the hidden beaches to the sea geyser, will stay with you long after the trip. The local food is a bonus, offering a taste of authentic Mexican flavors in a relaxed setting. And if you’re lucky with the timing, the whale watching and bird sightings will be truly memorable.
A Few Downsides
While the tour is generally praised, the dependence on sea conditions for certain stops, especially the Hidden Beach, could be frustrating if weather isn’t cooperating. Also, at nearly $190 per person, it’s on the higher end, though many consider the overall experience and inclusions worth it. For those uncomfortable with swimming or moderate activity, some parts may feel a bit challenging.
Who Should Consider This Tour?

This safari is perfect for adventure lovers who enjoy being in the water and exploring nature intimately. It’s well suited for families over 10 years old or groups of friends looking for a full, active day. If you’re sea lovers, wildlife enthusiasts, or simply want a more personalized experience away from crowded tours, this is a solid choice. Conversely, if you’re after a relaxed, beach-only day, or have mobility concerns, this might not be your best fit.
