small groups SAFARI to Marietas Islands including Hidden Beach

The big draw here is the swim through an underwater tunnel into Playa Escondida, or Hidden Beach, on Isla Redonda. You cover about 80 meters from the boat, wearing a life jacket and following a guide through the opening. It is a real little adventure, not a beach stop where you simply step ashore.

I like the small-group setup and the personal care from guides such as Eduardo, Daniel, Lalo, and Ismael. I also like the full morning: snorkeling, bird watching, the La Bufadora blowhole, seasonal whale watching, and fresh shrimp ceviche at El Anclote.

The catch is simple: you need moderate fitness and comfort in open water. Tide conditions can delay the start by about an hour, and access to Hidden Beach is not guaranteed if the water conditions are unsuitable.

Key points to know before booking

• Swim through an underwater tunnel: Reach Hidden Beach with a guided 80-meter swim from the boat.
• Small private group: Only your party takes part in the activity, giving the crew more time to help with swimming, photos, and snorkeling.
• Whales are seasonal: Humpback whale watching is offered from December 10 through March 23.
• Fresh food after the water activities: Finish with Acapulqueño shrimp ceviche, drinks, and dietary alternatives at El Anclote.
• Several wildlife stops: Look for blue-footed boobies, nesting birds, fish, stingrays, and, with luck, whales and dolphins.
• Surfing is optional: A beginner surf class at El Anclote costs an additional $30 per person.

Why Hidden Beach is the main event

The Marietas Islands are a group of rocky islands off the coast near Puerto Vallarta and Punta Mita. This tour focuses on the unusual way you reach Playa Escondida. Instead of walking down a trail, you swim from the boat and pass through a natural tunnel into a crater-like beach.

The swim is about 80 meters. That is not far for a strong swimmer, but it can feel longer when you are wearing a life jacket and moving through open water. A guide stays with you, and the crew has helped less confident swimmers make the crossing safely. One guide, Daniel, has even supported swimmers directly when they needed extra help.

Once inside, you have about 30 minutes at the beach. The setting is framed by rock walls and arches, with the round opening above giving the place its famous look. If the tide is low enough, you may also enter two nearby caves.

You should keep your expectations sensible. This is a protected natural site, and time in the crater is limited. The beach may also be inaccessible at certain tide levels. The operator may delay the start by about an hour while waiting for the water to drop enough for the tunnel crossing. You are told about such a delay one or two days before the trip when possible.

Calavera Reef brings the fish close

After Hidden Beach, the boat heads to the Calavera Reef area for about 35 minutes of snorkeling. The crew supplies snorkeling equipment and life jackets, then guides you through the water rather than simply dropping you at a spot and leaving you to figure things out.

Conditions can change. On one outing, the crew warned that visibility was not at its best, yet the water still offered schools of fish, different species, and a stingray. Other accounts describe seeing an eel and plenty of marine life around the islands.

That is the value of having an active guide. Ismael and Daniel have pointed out unusual fish and helped swimmers stay oriented. If you are new to snorkeling, stay close to the guide and ask questions. If you are experienced, you can still appreciate having someone identify what you are seeing.

Do not expect a guaranteed aquarium every time. Wind, current, and visibility affect the snorkeling. The broader trip helps balance that uncertainty, since you are not relying on one reef alone.

Secret Beach and the second crater

The next beach stop involves a shorter swim of about 10 meters. This Secret Beach becomes reachable when sea currents create the right conditions, so access depends on the day.

The stop lasts about 30 minutes and gives you another chance to swim among the islands’ rock formations. The setting is different from Hidden Beach, with arches and unusual stone shapes around the water. It is a pleasant second water stop, especially after the longer swim into the crater.

A practical point: you may have limited time to dry off between activities. Keep your mask, life jacket, and other gear organized on the boat. If you have a waterproof phone case, this is the kind of outing where you will use it often, though the guides also take photos at good points around the islands.

The crew’s help with photos is one of the nice personal touches. Daniel and Ismael have guided people into the best positions and taken pictures during the beach stops. That matters when your hands are occupied with swimming gear.

Puente de Piedra and La Bufadora

The boat also visits the second crater on Isla Larga, called Puente de Piedra, or Stone Bridge. Rather than landing, the captain brings the boat close beneath the arch. The stop lasts about 15 minutes and is mainly for viewing and photographs.

This part gives you a break from swimming while showing how dramatic the islands look from the water. The arch is also treated as a place to make a wish, a lighthearted tradition that fits the stop.

Farther north on Isla Larga, the boat approaches La Bufadora, a marine blowhole. Water shoots upward through the opening when conditions line up. The captain works close enough for a good view while keeping the boat at a safe distance.

The blowhole is a short stop, about 15 minutes. It is not a full activity on its own, but it adds movement and variety to the boat ride. You are not spending the whole morning in one cove.

Blue-footed boobies and island bird life

The islands are home to several bird species and nesting areas. The boat circles Isla Circular and Isla Larga so you can watch birds from the water, including the famous blue-footed booby.

You might see birds perched on the rocks, flying around the cliffs, or tending nesting areas. A particularly memorable sight can be a young blue-footed booby, and rare mating behavior has also been seen on this route.

Bring sunglasses and a hat, but secure both well. Most of the bird watching happens from the boat, so you are exposed to sun and spray. A camera with a strong zoom is useful, though you should not count on getting close enough for detailed bird portraits.

Winter whale watching adds real value

From December 10 through March 23, the tour includes up to 30 minutes of whale watching. Humpback whales use this area as part of their migration into and out of the bay. You may see mothers with calves, pods, breaches, or other surface activity.

Sightings are never guaranteed, but the timing is a strong reason to choose this tour in winter. Several outings have included multiple pods, nursing calves, and even a mating group. Dolphins have also appeared on occasion.

The captain’s skill matters here. Lalo has been praised for finding pods and positioning the boat safely. If whale watching is your top goal, book within the stated season and allow flexibility in your expectations. This is still a marine safari, not a show on a schedule.

Outside the whale season, the island visits, snorkeling, birds, beaches, and blowhole remain the main attractions.

Ceviche, cold drinks, and a relaxed finish

After the water activities, the tour ends at El Anclote with a one-hour food stop. The crew prepares Acapulqueño-style shrimp ceviche with boiled shrimp, orange juice, oregano, olive oil, avocado, tomato, onion, serrano peppers, and ketchup.

That last ingredient list tells you this is a Mexican beach-style ceviche rather than a strict coastal Peruvian preparation. The shrimp are boiled, not raw, which may suit you if you are cautious about raw seafood. The meal is served with drinks, including beer, soft drinks, and bottled water.

This is more than a snack. After several swims, the food gives the morning a proper finish, and the beach setting makes it feel like part of the experience rather than a rushed meal between stops. Eduardo has also arranged gluten-free tortilla chips and a vegetarian sandwich when needed. You should state dietary restrictions when booking so the crew can plan an alternative.

The surf class takes place here as an optional add-on. It costs $30 per person and lasts about 30 minutes. The beach has small, long waves suited to beginners, and the crew has taught teenagers and first-time surfers. If your group wants to surf, leave enough time for it. Cruise ship passengers may find the schedule too tight if the boat ride runs long.

What the small private format changes

This is a private activity, so only your group participates. That does not turn the boat into a luxury yacht. The boat is described as safe and practical rather than high-end, with room for a small group. Groups of eight have shared the boat with two additional people, giving you a useful sense of the scale.

The benefit is attention. A guide can help a nervous swimmer, explain fish, take photographs, and adjust the pace more easily than on a large excursion. Eduardo has also helped with practical problems before the tour, including arranging a driver after vehicle trouble affected one outing.

That personal service is likely to matter most if someone in your party is not a strong swimmer, has dietary needs, or wants to combine snorkeling with surfing. If you prefer a quiet boat ride with little interaction, the friendly, hands-on approach may feel more active than you want.

The listed price is $212.09 per person. That is a serious half-day expense, but it covers equipment, life jackets, food, bottled water, soft drinks, beer tasting, the private format, and several separate island activities. You are paying for a broad day on the water and a small crew, not just transportation to one beach.

The optional surf lesson costs extra, despite the general inclusions mentioning a beginner surf class. Treat the $30 fee as the operative price for surfing and confirm it when booking.

Timing, fitness, and who should choose it

The tour starts at 9:00 a.m. from Av. El Anclote 20 in Corral del Risco, near Punta de Mita. It normally lasts about four to five hours, though individual outings have sometimes been shorter. The experience ends back at the same meeting point.

You should be comfortable swimming in open water and handling repeated water activities. The operator recommends a moderate fitness level, sets the minimum age at over 10, and limits participation to adults under 65. Those rules are important because the main attraction requires swimming through a tunnel, not simply boarding a boat.

I would choose this for an active couple, a family with older children, or a group of friends that wants more than a standard sightseeing cruise. It is especially appealing during whale season, and it works well for people who care about photos, wildlife, and personal guidance.

I would hesitate if anyone in your group cannot swim, dislikes saltwater activity, needs a rigid return time, or expects guaranteed access to every beach. You can ask for assistance, but the tour remains physically active and dependent on tides, weather, and sea conditions.

The operator confirms the booking at the time of purchase. Service animals are allowed, and the meeting point is near public transportation. Cancellation is free up to 24 hours before the start time. A cancellation made later is not refundable, and poor weather may lead to a different date or a full refund.

Should you book this Marietas Islands safari?

I would book it if Hidden Beach is high on your Puerto Vallarta list and you want a small, active outing rather than a large boat transfer. The strongest reasons are the guided tunnel swim, the chance to see several kinds of marine life, winter whale watching, and the generous finish with shrimp ceviche and drinks.

The price is easiest to justify when your group uses the personal service, snorkeling, bird watching, and beach stops. Just be honest about the swim, allow for tide delays, and treat whales and Secret Beach as conditions-dependent bonuses.

For strong swimmers and curious families, this is a well-packed way to see the Marietas Islands. For anyone seeking a passive cruise, choose another style of boat trip.
