small groups SAFARI to Marietas Islands including Hidden Beach

When you think about a day trip from Puerto Vallarta that offers both adventure and awe, a small-group safari to the Marietas Islands should be near the top of your list. For around $190 per person, you get about 4 to 5 hours of exploring some of Mexico’s most stunning marine and island landscapes. Led by passionate local guides, this tour promises a personalized experience with fewer than 10 participants, ensuring you’re not just another face in the crowd.

What makes this trip stand out? First, the entry into Playa Escondida, which involves swimming through a marine tunnel inside a volcanic crater—an experience both thrilling and scenic. Second, the variety of stops: from snorkeling at Calavera Reef to visiting an inaccessible Secret Beach that is only available during certain sea conditions. The tour also offers bird watching, whale sightings (seasonal), a marine geyser, and a delicious ceviche lunch.

A possible consideration? The timing can hinge on tides; sometimes, you might need to wait an extra hour to swim through the tunnel safely. This means flexibility is key, especially if you’re visiting during high tide or rough weather. But if you’re comfortable with some water activity and enjoy a well-paced, intimate tour, this shouldn’t be a problem.

This experience is perfect for adventurous travelers who love snorkeling, wildlife, and discovering quiet, natural spots. It’s also ideal for those who value small groups for a more personalized and relaxed vibe—something quite different from the large cruise-style tours.

Key Points

• Personalized small-group experience enhances comfort and interaction.
• Multiple stops showcase marine life, bird species, and breathtaking geological formations.
• Swim through a marine tunnel inside a volcanic crater — a highlight for adventure lovers.
• Seasonal whale watching offers extraordinary wildlife encounters.

The Marietas Islands are a string of volcanic islets off the coast of Puerto Vallarta that pack a punch of natural beauty and intrigue. This tour takes you on a carefully curated journey through some of their most iconic sites, combining adventure, wildlife sightings, and cultural surprises.

The Itinerary Unpacked

Entry to Playa Escondida (Hidden Beach)

Our adventure begins with a swim of about 80 meters from the boat to Playa Escondida, a secluded cove famous for its natural oval opening. You’ll be guided into the crater’s interior through a marine tunnel, which is an experience you won’t soon forget. The water crossing takes roughly 6-7 minutes, and with life jackets provided, the guides ensure it’s safe for everyone comfortable with swimming.

Reviewers rave about this part — Megan_O calls it “the highlight of an incredible week” and David_W describes the hidden beach as “magical.” Being able to stand inside a volcanic crater with the sky peeking through the natural arch makes this a must-see. Keep in mind, this activity is tide-dependent; the guide will notify you if you need to wait for a better window, which can add about an hour to your wait.

Snorkeling at Calavera Reef

Next, you’ll don snorkeling gear and explore Calavera Reef, home to fish that grow their own food—a fascinating tidbit for marine enthusiasts. The clarity and vibrancy of the water are often praised, and the guides are skilled at pointing out interesting marine life, from colorful fish to eels.

Reviews highlight that snorkeling in this sanctuary is “fantastic,” with one guest mentioning the fish and coral as “crazy fish with amazing colors.” Putting on the equipment in a smaller group means you get more attention and can easily spot marine creatures along the way.

The Secret Beach

Thanks to changing sea currents, the Secret Beach becomes accessible only during specific times of the year. When conditions permit, you’ll have a chance to swim to this secluded spot, which remains largely hidden except during these windows. The beach itself is pristine, and the experience of reaching it feels like discovering a secret paradise.

One reviewer called it “mind-blowing,” emphasizing the rarity of being able to access it. Again, this stop depends on the tide, so plans might adjust based on current conditions. It’s an exclusive peek at untouched natural beauty.

The Second Crater: “Stone Bridge” and the Sea Geyser

The tour also includes visiting the second crater, known as “Puente de Piedra” (Stone Bridge). The boat approaches just under a natural arch where you can wished upon the tranquil waters below. The Sea Geyser or “Blowhole” is another highlight—standing on deck as powerful jets of water shoot skyward is both awe-inspiring and fun.

Bird Watching and Wildlife Sightings

The islands are a birdwatcher’s paradise with species like the Blue-footed Booby and others. The guides are praised for their knowledgeability, helping guests identify birds and learn about their behaviors. Some guests have even seen blue-footed boobies mating—a rare, memorable sight.

Whale Watching (Seasonal)

From December to March, the waters around the islands become prime whale-watching territory. Guests often spot humpback whales and their calves. Megan_O calls this “a great experience,” adding that seeing whales jump out of the water is “unforgettable.” It’s a seasonal treat that enhances the tour’s appeal.

A Tasty Touch: Ceviche and Drinks

Lunch is a highlight for many—a freshly prepared Acapulqueño-style shrimp ceviche featuring boiled shrimp, orange juice, avocado, and spicy peppers. It’s a refreshing, flavorful break after the water activities. Beers, sodas, and bottled water are also included, making this a well-rounded experience.

Optional Surf Lesson

For those interested in learning to surf, the tour offers a 30-minute beginner’s class on a beach known for its friendly, small waves. No previous experience is required, and the instructors are gentle and encouraging. It’s a perfect addition if you want to try catching your first wave.

What Sets This Tour Apart?

The small group size — less than 10 people — makes the entire day feel more intimate and flexible. Guides like Eduardo and others are praised for their knowledge, friendliness, and attentiveness, often going above and beyond to ensure guests see whales, fish, and birds. Megan_O notes, “Eduardo was a great guide,” and Jamie_R shares that “our guides took us to the hidden beaches and made it all very safe and easy.”

The variety and intensity of stops truly give a full picture of the islands’ beauty and biodiversity, making it worth the price. With admission tickets included for most stops, the cost reflects good value—especially considering the delicious lunch and snorkeling gear.

Practical Considerations

While the tour is packed with activities, it does require a moderate physical fitness level—swimming, snorkeling, and some walking are involved. The timing flexibility is essential; as the tide influences access to some spots, expect some waiting. Weather conditions can also affect the experience, so it’s good to have a backup date in case of rough seas or high tide.

The tour begins at 9:00 am from the meeting point in Corral del Risco, and you’ll return there at the end of the day. It’s family-friendly for children over 10, but younger kids might find the water activities challenging.

If you’re craving an adventure-packed day that combines nature, wildlife, and cultural discovery, this safari tops the list. The personalized group size guarantees you’ll get plenty of attention, making it perfect for couples, families, or small groups who prefer a more relaxed, authentic experience. The tour’s focus on marine ecosystems, birdlife, and geological marvels makes it an educational as well as fun outing.

The diverse stops—hidden beaches, snorkeling, whale watching, and the marine geyser— suit travelers who love variety and don’t mind a bit of water-based activity. If you want a high-value, memorable day exploring the natural beauty just off Puerto Vallarta, this tour offers it all.

The delicious ceviche and drinks also make the day feel complete, providing a genuine taste of local flavors. It’s well-suited for travelers who want more than just a boat ride—those seeking authentic encounters with nature and a chance to connect with the environment in a meaningful way.
