small groups SAFARI to Marietas Islands including Hidden Beach

The star of this trip is the swim through a short underwater tunnel into Playa Escondida, better known as Hidden Beach. You cover about 80 meters from the boat in a life jacket, guided by the crew, then pass through the tunnel into a crater beach framed by rock. It is a rare kind of beach visit: getting there is part of the attraction.

I like the small-group format, which lets guides such as Eduardo, Daniel, Lalo, and Noe give close help in the water and take photos. I also like the full mix of activities: snorkeling, bird watching, whale watching in season, the La Bufadora blowhole, and a very good shrimp ceviche meal. The main drawback is simple: you need moderate fitness and comfort in open water. Tide and weather can also change the plan, and the Hidden Beach swim may start about an hour late.

Key points at a glance

• Hidden Beach requires a swim: You travel about 80 meters from the boat, then pass through an underwater tunnel while wearing a life jacket.
• Small groups matter: The boat has been described as carrying up to 10 people, and the activity is private to your booked group.
• The itinerary packs in a lot: You get Hidden Beach, snorkeling, Secret Beach, rock arches, birds, a blowhole, and seasonal whale watching.
• Lunch is part of the appeal: Shrimp ceviche, beer, soft drinks, and bottled water are included, with food adjustments available for dietary needs.
• Whales are seasonal: Whale watching is offered from December 10 through March 23, but sightings are never guaranteed.
• The price rewards personal service: At $212.09 per person, this costs more than a basic boat trip, but the smaller group and hands-on guiding add real value.

Why the Hidden Beach swim is the main event

Marietas Islands are best appreciated from the water, but Playa Escondida gives you a clear goal. The boat approaches Isla Redonda, and you swim roughly 80 meters with a guide before reaching the tunnel into the crater. Life jackets are required, and the crew accompanies you throughout.

The entrance depends on sea conditions. If the tide is low enough, you may also enter two caves beside the beach. If the tide is high, the operator may wait before starting. That delay can last about an hour, so do not plan a tight connection afterward.

Inside, the beach feels enclosed by the island itself. You get around 30 minutes at this stop, enough for photos and a close look at the unusual rock setting. Guides have been especially helpful with hesitant swimmers, including assisting people who needed extra support in the water.

This is not a walk-up beach stop. The swim is short for a fit person, but it can feel demanding if you are nervous in open water. You should be comfortable floating in a life jacket and following directions. The stated age range is children over 10 and adults under 65, with moderate physical fitness expected.

Snorkeling at Calavera Reef

After the crater beach, the boat moves to the Calavera Reef area for about 35 minutes of snorkeling. Equipment and life jackets are provided, and a guide stays with you while you look at the marine life around the islands.

Conditions can affect visibility and the number of fish you see. Even so, the trip has included schools of fish, unusual individual fish, an eel, a stingray, crabs, coral, and a young blue-footed booby near the water. The crew also points out marine life that is easy to miss when you are looking only at the larger sights.

I like this part because it gives the day a slower rhythm after the excitement of Hidden Beach. The snorkeling is not just a quick swim before lunch. You have time to get settled in the water, use the provided equipment, and follow the guide toward interesting spots.

If snorkeling is the main reason you want to visit Marietas, keep your expectations tied to weather and sea conditions. The islands offer a striking setting, but nature controls visibility. A day with rough water may be less impressive underwater than a calm day.

Secret Beach and the second crater

The third water stop is Secret Beach, reached by swimming about 10 meters from the boat. A natural change in sea currents can make this beach accessible at certain times, but it remains unavailable for much of the year.

That uncertainty is important. You should see this as a possible bonus, not the one feature to count on. When access is possible, the setting includes rock formations and arches, and the swim is shorter than the one to Hidden Beach.

The boat then visits Isla Larga and the second crater, known as Puente de Piedra, or Stone Bridge. You do not need to swim ashore here. The boat moves beneath the arch for about 15 minutes, creating a good chance to look up at the rock structure and take pictures.

This stop works well as a change from the beaches. You are no longer focused on getting through a tunnel or spotting fish. Instead, you are seeing how the islands have been shaped into caves, arches, and openings by the sea.

Bird watching around Isla Circular and Isla Larga

The boat circles portions of Isla Circular and Isla Larga while the crew points out nesting areas and island birds. The blue-footed booby is the most famous resident, and the route can also reveal other species living on the rocky islands.

Bird watching here is done from the boat, so you are not walking through nesting areas. That keeps the visit practical and respectful of the marine sanctuary. Bring patience. Birds may be perched close to the water, high on the rocks, or easy to miss while the boat is moving.

The guides add value by showing you where to look. Daniel, in particular, has been praised for helping people notice the smaller details around the islands, while captains such as Lalo have been singled out for safe boat handling near the rock formations.

Whale watching from December 10 through March 23

If you visit between December 10 and March 23, the route includes time for whale watching. The Marietas area is used by migrating whales entering and leaving the bay, and the trip may encounter mothers with calves or groups of whales.

The schedule allows about 30 minutes for this part. You might see several pods, a mother and calf, or whales breaching. You might also see no whales at all. The crew can search, but sightings remain dependent on animal movement and sea conditions.

This seasonal timing can make the tour especially appealing in winter. It also means you should not judge the trip only by the whale portion if you visit outside those dates. The islands, snorkeling, beaches, birds, and blowhole remain the core of the outing.

La Bufadora, the marine geyser

North of Isla Larga is La Bufadora, a blowhole where seawater can shoot upward through the rock. The boat approaches below the opening for about 15 minutes.

This is a short stop, but it adds a bit of drama to the route. The captain has to balance a close view with safe boat handling, and the exact display depends on the sea. You may get a strong burst of water, or a smaller one if conditions are calm.

It is also a good photo stop because you see the relationship between the moving sea and the island rock. Just protect cameras and phones from spray.

Shrimp ceviche at El Anclote

After the island route, you return to El Anclote for the meal. The included dish is Acapulco-style shrimp ceviche made with boiled shrimp, orange juice, oregano, olive oil, avocado, tomato, onion, serrano pepper, and ketchup.

The ceviche is prepared as part of the experience, rather than treated as an afterthought. Beer tasting, soft drinks, and bottled water are also included. This is exactly the kind of ending that works after several hours in salt water: simple food, cold drinks, and time to sit down.

Dietary adjustments are available. The crew has prepared gluten-free tortilla chips and a vegetarian sandwich, and the operator says other options can be arranged for dietary restrictions. Tell them in advance. Do not assume a special meal will appear without notice.

The meal is one reason the price feels more reasonable than a basic island transfer. You are paying for food, drinks, equipment, guiding, and time at several sites, not just transport from shore to shore.

Optional surf lesson at El Anclote

A beginner surf class is listed among the included features, but the detailed schedule describes it as optional and priced at an additional $30 per person. Confirm the current arrangement before booking.

The lesson lasts about 30 minutes and uses the beach at El Anclote, described as having small, long waves suitable for first-time surfers. This is aimed at beginners, not people looking for a serious surf session.

It can be a fun add-on for families or groups with teenagers. Several young participants have enjoyed getting up on the board with patient instruction. Still, it can be skipped if you need to return to a cruise ship, have limited time, or simply want to end the day with lunch.

Small boat, personal attention, and the real value

The listed price is $212.09 per person. That is not bargain pricing for a four to five-hour boat outing, but this is not a standard large-group cruise either. The activity is private to your group, and the boat has been described as holding up to 10 people.

That smaller scale matters most during the swim to Hidden Beach. A guide can stay close to a nervous swimmer, help with the route, and take photos without managing a large crowd. Eduardo has also been responsive with pre-trip questions, and the crew has helped arrange practical details such as transportation to the meeting point.

The boat is functional rather than luxurious. That is worth knowing before you pay the higher price. You are buying access, guiding, flexibility, and a compact group, not a polished yacht or resort-style vessel.

The trip can also run shorter than the advertised four to five hours. One outing lasted about three hours, likely because timing, conditions, and the number of stops can change. If you need a precise end time, ask before departure.

Meeting point, timing, and who should book

You meet at Av. El Anclote 20 in Corral del Risco, Nayarit, at 9:00 am, and return to the same point. The location is near public transportation, though the operator has also helped arrange a driver when needed.

The tour is best for people who want an active morning on the water, not a passive sightseeing cruise. You should be prepared to swim, climb in and out of the boat, wear a life jacket, and follow directions in changing sea conditions.

Children must be over 10, and adults must be under 65 according to the stated requirements. Service animals are allowed. The activity requires good weather, and poor conditions can lead to a different date or a full refund.

You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations inside that window are not accepted for a refund.

Should you book this Marietas Islands tour?

Book it if Hidden Beach is a priority, you are comfortable swimming in open water, and you value a small group with close help from the crew. The combination of the tunnel swim, snorkeling, birds, possible whales, the blowhole, and ceviche gives you a full day’s worth of variety in a compact outing.

Think twice if you want a luxury boat, a guaranteed whale sighting, or a fixed schedule. Tide delays, weather, sea conditions, and access to Secret Beach can change the plan. At $212.09, the trip makes the most sense for you if personal attention and a small boat matter more than saving money.
