Private Marietas Snorkeling Tour – Hidden Beach Access Guaranteed

The main event here is the short swim through a cave to Hidden Beach, a striking pocket of sand tucked inside the Marietas Islands. You get roughly 20 to 25 minutes inside, enough time to swim, take photos, and enjoy the unusual setting before returning to the boat.

I like the private group format, which lets your guide adjust the pace and give close attention to your snorkeling gear. I also like the practical conservation touch: the islands are plastic-free, and the boat provides water refills and eco-friendly cups.

The catch is that Hidden Beach is not included in the advertised price. You pay MX$600 per person in cash for that activity, plus a MX$100 government fee per person, and the cave swim requires calm nerves, steady swimming, and some physical stamina.

Key points to know before booking

• The cave swim is the signature moment: You pass through a cave entrance by swimming, then spend about 20 to 25 minutes at Hidden Beach.
• Your boat is private: The $650 price covers a group of up to four, not four separate tickets.
• Snorkeling conditions can change: Water clarity depends on the sea and weather, even in this protected marine area.
• Plan for extra cash: The MX$600 Hidden Beach fee and MX$100 government fee per person are separate from the tour price.
• This is an active outing: You should have moderate physical fitness, and Hidden Beach is limited to people age 10 and older, with an adult in the same group.
• The tour is eco-minded: Marietas Islands are a plastic-free zone, with a refill station on the boat.

Why the Marietas Islands are worth the boat ride

The Marietas Islands sit off the coast of Puerto Vallarta and can be reached only by water. That alone gives the outing a sense of separation from the mainland. You leave Marina Vallarta by boat and spend the day around a protected island area known for marine life and seabirds.

I like that the trip is not just a quick photo stop at a famous beach. The boat ride leads into a guided snorkeling session, with time to look beneath the surface and watch for fish and other sea life. The water is described as clear, but you should keep your expectations sensible. Visibility changes with wind, waves, and recent weather.

This is also a useful setting for a private tour. With only your own group aboard, you can ask for help with your mask and snorkel, take a little time getting comfortable, and keep the pace suited to your group. That matters more here than it might on a simple sightseeing cruise because the most exciting parts require coordination in the water.

The overall rating is 4.8 from 82 reviews, with 94 percent of customers recommending the tour. Those numbers suggest a reliable outing, but they do not remove the normal limits of a sea-based activity. Weather and water conditions still shape the day.

Starting at Marina Vallarta

You meet at Tours Eco Explorer VallartaProa 22 in Marina Vallarta, Puerto Vallarta. At check-in, your guide welcomes you, confirms your booking, and supplies the snorkeling equipment.

Bring your identification. Every person must show an ID at check-in, and you will not be allowed to board without it. This is an easy detail to miss when you are heading out for a casual morning on the water, so keep your identification handy rather than buried in luggage.

The company provides the basic snorkeling gear, and the guide helps you prepare before you head to the pier. That early equipment check is useful because a loose mask or poorly fitted snorkel can turn a pleasant swim into a frustrating one.

From the meeting point, you walk to the pier and board the boat. The entire outing lasts about four hours and ends back at the same meeting point. Since the tour is private, the $650 price covers up to four people in your group. For four people, that works out to $162.50 each before the additional fees. For one or two people, the per-person cost is much higher, so the value improves when you fill the boat.

The boat trip to Islas Marietas

The boat ride is part of the appeal. You leave the marina behind and travel toward islands that have no road access. The trip gives you a change of scene before the active portion begins, with open water and the islands ahead.

The exact ride conditions depend on the sea. You may find a smooth crossing, or you may feel more movement on the way out. If you are prone to motion sickness, plan carefully, though the supplied information does not specify whether medication or special seating is available.

The crew includes a guide and captain, and the private setup means you are not sharing the boat with a large party. One family described being especially well cared for with only four people aboard, which makes sense: a small group allows the crew to watch your comfort and answer questions without splitting attention among dozens of people.

Snacks include apples, bananas, and a sandwich, along with soda. Lunch is not included, so do not treat the snack as a full midday meal. The outing is short enough that the provided food may be adequate for some people, but anyone with a larger appetite should eat before departure.

Guided snorkeling around the protected islands

At the islands, your guide leads the snorkeling portion. The attraction is not only the scenery above the water, but the chance to see marine life in a protected natural area.

Your guide helps you secure the mask and snorkel before you enter the water. That kind of hands-on instruction is valuable if you are rusty, have never used the equipment, or are traveling with children old enough to join the tour. One particularly useful piece of advice from the available feedback is to make sure the gear is properly secured before you start swimming.

Water clarity can vary. On a calm, clear day, you may have a good view of fish and underwater life. If the sea is stirred up, the snorkeling may be less impressive. I would book this for the full setting and the chance to snorkel, not on the promise of perfect visibility.

The islands also provide opportunities to see seabirds. You should keep the focus on observation rather than expecting a full wildlife expedition. The experience is built around a compact visit to the islands, with snorkeling and, if selected, the cave swim as the central activities.

Swimming through the cave to Hidden Beach

The optional Hidden Beach visit requires the most effort and creates the strongest memory. You may wait briefly for your scheduled turn before swimming through the cave entrance.

The passage is short, but it can feel demanding if you are anxious in enclosed spaces or uncomfortable in open water. The narrowest point clears quickly, then the cave opens toward the beach. The most useful approach is to stay calm, follow the guide’s instructions, and use a steady breaststroke rather than rushing.

You should also have reasonable cardio stamina. The swim is not presented as a long endurance test, but you need enough strength to move through the entrance and return safely. The cave is not a good match for someone who panics in confined spaces or struggles in the water.

Once inside, you have about 20 to 25 minutes to swim, rest, take photos, and enjoy the beach. That is enough for a memorable stop, but not enough for an unhurried beach afternoon. Keep your expectations focused: this is a brief, unusual visit reached by water, not a long stay on a conventional beach.

Hidden Beach access is available Tuesday through Sunday. The tour does not run on Mondays, and the Hidden Beach visit itself is limited to Tuesday through Sunday. The entrance fee is optional and costs MX$600 per person, payable in cash. Since the title of the outing emphasizes access, confirm the exact arrangement at booking and arrive prepared to pay the separate fee if you choose to go inside.

What the private format changes

The private arrangement is one of the tour’s strongest features. You are not adapting your morning to a large group of strangers. Instead, the guide can spend more time making sure your mask fits, explaining the swim, and responding to your comfort level.

That is especially helpful for families. The minimum recommended age for the tour is 10, and the minimum age for Hidden Beach is also 10, with an adult in the same group. Children should be confident enough in the water to follow directions and remain calm at the cave entrance.

The private format also helps couples and small groups who want a more personal outing. You can enjoy the boat ride, snorkeling, and island visit without the noise and delay that often come with a crowded excursion.

Still, private does not mean fully flexible in every detail. The Hidden Beach swim involves timing and a possible wait. You also need to work within sea conditions and park rules. The private boat gives you a more personal experience, not a guarantee that the ocean will follow your schedule.

Price, extra fees, and what is included

The base price is $650 per group of up to four. Included are the boat ride, snorkeling equipment, a conservation donation to Bahia Unida, the CONANP federal fee, national park permits, snacks, and soda.

That is a fairer deal for a full group of four than for a solo customer. Four people sharing the price receive a private boat, gear, food, and the guided island visit. For two people, the cost per person rises, but you are still paying for privacy rather than a seat on a shared excursion.

Budget separately for two charges:

• MX$100 government fee per person
• MX$600 Hidden Beach entrance fee per person, payable in cash if you select that activity

For four people who all choose Hidden Beach, those extra charges total MX$2,800, or MX$700 per person. That amount is in addition to the $650 group price. Currency conversion will change with exchange rates, so confirm the current peso amount when booking or at check-in.

Lunch is not included. The fruit and sandwich are useful, but I would not count on them as a large meal. A refillable water bottle is the smarter item to bring. The islands are plastic-free, and the boat has a water refill station plus eco-friendly cups.

Who should book this tour

I would choose this outing if you want a small, active boat trip rather than a passive cruise. It suits people who enjoy snorkeling, can manage a short cave swim, and want the convenience of a private group.

Families with children age 10 or older may find the setup appealing, provided everyone is comfortable in the water. Couples and small groups also get better value when four people share the $650 cost.

I would think twice if you are looking for a long beach stay, guaranteed clear water, or a relaxed boat ride with no physical demands. Hidden Beach requires swimming through a cave, and snorkeling quality depends on the conditions. Pregnant women are not permitted, and the tour is not recommended for anyone under the influence of drugs or alcohol.

The recommended maximum age for Hidden Beach is 65. That does not mean every person over 65 will have the same ability, but it does signal that the cave swim is not designed as an easy-access activity. You should honestly assess your swimming ability and comfort before paying the separate entrance fee.

Booking dates, weather, and cancellations

The tour is offered daily except Monday, while Hidden Beach access is available Tuesday through Sunday. It is commonly booked about 27 days ahead, so I would reserve early if your Puerto Vallarta dates are fixed.

You receive confirmation when you book, and mobile tickets are accepted. The activity is offered in English. Public transportation is nearby, which makes the Marina Vallarta meeting point reasonably practical, though you are responsible for reaching Tours Eco Explorer VallartaProa 22 on time.

The tour requires good weather. If poor conditions force a cancellation, you can choose another date or receive a full refund. The same choice applies if the minimum number of participants is not met.

You can cancel for a full refund up to 24 hours before the start time. Cancellations or changes made less than 24 hours before departure are not refunded or accepted, and the cut-off follows local Puerto Vallarta time.

If you are arriving by cruise ship, confirm your arrival time in Central Time. That detail matters because a misunderstanding about time zones could make a short tour impossible to catch.

Should you book the Marietas Islands tour?

I would book it if the cave swim is the reason you want to visit the Marietas Islands and you can share the cost with three other people. The private boat, included equipment, guided snorkeling, snacks, and brief Hidden Beach visit make this a focused half-day outing with a clear main attraction.

Go in knowing what you are buying. The beach stay lasts only 20 to 25 minutes, the entrance fee is extra and cash only, water visibility can change, and the cave requires calm swimming. If those limits fit your plans, this is a strong choice for a private Puerto Vallarta day on the water. If you mainly want an easy beach break, choose a tour without the cave swim.
