Marietas feels like a secret mission. This private tour is built around the walk-in magic of Playa Escondida, reached by swimming through a natural tunnel with a certified guide. I also like that you get hands-on snorkeling gear plus non-alcoholic drinks, and the guide helps with photo moments by safely handling your phone. The main thing to consider is that this is weather-sensitive: strong wind and waves can make the boat ride rough, and you’ll want to confirm safety basics (like emergency communication) before you head out.

What you’re really buying is time and attention. In about 3 hours, you’ll do the exclusive beach access, a short stay on the sand, snorkeling with included equipment, and a self-paced walk at Playa Nopalera. It’s private for up to 8 people, so you’re not stuck in a long cattle-line shuffle.

One practical drawback: there are rules you have to follow to make the visit possible. You’ll swim without shoes (and you can’t bring bags or backpacks down to the beach), and you’ll need a moderate fitness level for that tunnel swim.

Key things to know before you go

• Playa Escondida access is a tunnel swim: expect about an 80 to 100 meter swim with your guide
• Your phone gets handled for you: the guide can safely carry it and help with pictures during the experience
• Beach time is short on purpose: plan for about 30 minutes at Playa Escondida
• Snorkeling is included (with gear): you’ll get equipment and do snorkeling after your beach stop
• Playa Nopalera is more freedom: you can walk around natural caves at your own pace
• Weather can change comfort fast: the tour needs good conditions, and wind/waves can make the boat ride bumpy

Marietas Islands and Playa Escondida: why this swim is the whole point

Marietas Islands are famous for one reason: you can’t just stroll to the star beach. Playa Escondida (Playa del Amor) is inside a natural cavity, and that means access works like a guided shortcut to the island’s best view.

The experience starts with a private boat departure from Punta Mita Pier, then a quick sail (usually around 15 to 20 minutes, depending on sea conditions). Once you reach the right spot, you enter the beach area by swimming through a natural tunnel. This isn’t a “romantic beach stroll.” It’s more like a short, active passage—still guided, still safe, but physical enough to matter if you’re not comfortable in open water.

This is also why the timing feels tight. You’re not spending hours lounging. Instead, you get a focused package: tunnel swim, a brief beach moment, snorkeling, and then a different shoreline walk at Playa Nopalera.

Punta Mita Pier logistics: private pace, quick sailing, and weather reality

The tour runs about 3 hours total. You’ll start at Punta Mita Pier and board a private boat to Marietas Islands. Because it’s private, your group gets your own flow—no waiting for other tours, no merging with strangers.

Still, your comfort depends heavily on the sea that day. This kind of boat ride can be smooth, or it can be bouncy. If the wind picks up, the crossing can take longer than the ideal time, and waves can splash into the boat. That’s not unique to this tour; it’s the physics of open water.

Here’s the practical move: when conditions are windy, ask how they handle safety and emergency readiness onboard. The tour is built for “good weather,” and the itinerary is designed for that. If anything feels off about onboard safety equipment or communication, you should speak up before you leave the pier.

Good news: the tour includes lifejacket and stays with a certified guide during the swim. That matters. A strong sea day is about more than comfort—it’s about having the right procedures.

The Playa Escondida tunnel swim: what to expect and how to prepare

After you arrive, the guide leads the entrance to Playa Escondida. The route is by swimming through a natural tunnel—about 80 to 100 meters—and you’ll be accompanied by the guide the whole way.

Plan your expectations around two realities:

1. The tunnel swim requires steady comfort in the water.
2. You’ll need to think about what you’re wearing and bringing, because certain items aren’t allowed down onto the beach area.

The tour helps in a few important ways. You’ll get a waterproof bag or container to transport your phone or camera to the beach. And during the experience, the guide can take photos and help capture the best angles—while keeping your device secure.

That’s one of the underrated benefits of this tour. A lot of beach tours say they’ll help you take photos, but they often mean a quick snap. Here, the setup is actually made for the moment you’re in: tunnel swim + beach arrival. It’s the kind of help that saves you from worrying about gear in an active setting.

You also get a set amount of time on the sand—about 30 minutes. It’s enough to enjoy the setting and take photos, but it’s not a long lounge session. If you want a long beach day, you’ll likely want to pair this with extra time on your own later.

Snorkeling after the beach: included gear and a lighter pace

Right after Playa Escondida, the tour shifts from swimming into snorkeling. You’ll have snorkeling equipment included and a chance to see underwater life along the way.

The itinerary doesn’t promise a specific type of fish or reef experience, but the value is that you’re not paying extra for gear and you’re not hunting for rentals. When time is short, included equipment is a real convenience.

Then you’ll head to Playa Nopalera, where you can walk and explore natural caves at your own pace. This is a nice balance: snorkeling is guided and structured, but Nopalera gives you some freedom to move slowly, take in the shoreline, and decide how much cave exploration you want.

One small mental tip: after the tunnel swim, your body may feel warm and a little tired. The Nopalera walking feels like an easy step down from “active water time.” Pace yourself, drink what you brought, and don’t rush the caves if you’re low on energy.

Playa Nopalera caves: walking freedom without the pressure

Playa Nopalera is where the tour lets you slow down. You’ll arrive after snorkeling and then have time to walk around and explore natural caves independently.

Because the caves are on your time, you can decide:

• stay near the entrance for photos and quick views
• walk deeper if it feels comfortable
• turn back early if you’d rather keep the energy for the return boat

This freedom is one of the best “value-per-minute” parts of the itinerary. A tight schedule can feel stressful, but here the itinerary gives you a stretch of independent exploration.

Price and what it really means: $1,185 per group for up to 8

The price is listed as $1,185.47 per group, up to 8 people, with about 3 hours on the water. That sounds high until you break down what’s included.

You’re paying for:

• private boat transfer from Punta Mita area
• admission/access to Playa Escondida / Playa del Amor
• a certified guide during the tunnel swim
• snorkeling equipment
• lifejacket
• non-alcoholic beverages
• a waterproof container for your phone/camera
• an environmental rules-based experience where they manage what goes to the beach

There’s also the practical benefit of group size. If you fill the group (up to 8), the per-person cost drops a lot compared to sharing with strangers. If you’re traveling as a couple or small family, you may pay more per person—but you still get the “private for your group” pacing.

A quick realism check: because the tour depends on good conditions and limited spaces, you’re not just buying a ticket. You’re buying a scheduled window that the team will run if the weather allows. That’s part of the value, and it’s why reserving in advance is smart.

What to bring (and what not to bring) so the day runs smoothly

This tour has rules that are there for safety and environmental protection. If you ignore them, you can slow everyone down.

Bring:

• swimsuit
• towel
• sunscreen
• camera or cell phone (protected in the waterproof container)
• drinks in thermoses or reusable bottles (the tour includes non-alcoholic beverages, but having your own reusable drink is allowed)

Not allowed:

• going down to activities with shoes of any kind
• bags, backpacks, or suitcases to the beaches
• food and/or drinks on the beaches
• throwing garbage into the sea
• alcohol during your stay in Marietas (it’s only allowed on the way there and back)
• drones (per CONANP regulations)

Minimum age is 10 years, maximum age is 64 years, and you’ll need moderate physical fitness. Also, confirmation happens within 48 hours of booking, subject to availability, and the tour is offered in English.

One more helpful detail: you’ll use a mobile ticket. Keep it accessible on your phone, but remember your device will also need to be secured in the waterproof container during the beach access.

Meeting points and timing: where you start and where you end

You meet at GRIMAR ADVENTURES Excursions Islas Marietas Islands – Ballenas – Whales Watching, Av. Las Pangas 18, 63734 Corral del Risco, Nay., Mexico.

The tour ends at Punta de Mita pier, with the end address listed as Av. El Anclote 24, 63734 Corral del Risco, Nay., Mexico.

This can feel a little confusing if you’re trying to map everything day-of. My advice is simple: save both addresses in your maps app and plan to be early. Even a small delay is annoying when your time on Playa Escondida is only about 30 minutes.

Also, the meeting location is described as near public transportation, which can help if you’re not taking a private driver.

Weather, safety, and that one big question you should ask

The tour requires good weather. If conditions are poor, it can be canceled, or you’ll be offered another date or a refund. That’s the “official” side.

The “real world” side is comfort and safety on the boat and during the swim. One past booking account raised concerns about strong wind/waves and whether an emergency radio was onboard, after which the group decided to turn back. You don’t need to panic about this, but you should treat it as a reminder to ask the right questions.

Before departure, ask:

• how they assess wind and waves
• what safety equipment is onboard (including emergency communication)
• whether the crew has a plan for rough conditions

If your guide answers calmly and clearly, you’ll feel better. If answers feel vague, that’s your cue to choose your comfort level.

Should you book this hidden beach tour?

I’d book this if you want:

• a private Marietas experience from Punta Mita
• access to Playa Escondida that isn’t a “try it yourself” situation
• snorkeling equipment provided
• a short, efficient 3-hour format that includes both beach time and underwater time

I would skip or reconsider if:

• you’re not comfortable swimming in open water or through a natural tunnel
• you hate bouncy boat rides
• you want a long beach day (this is about the moment, not all-day lounging)
• your group has low flexibility for weather changes

If you do book, bring your best “active beach day” mindset: swimsuit, no shoes in water areas, minimal personal items, and a willingness to move with the tide and conditions.
