Marietas Islands put the ocean on stage. From Sayulita, you cruise to the Bay of Banderas and the Marietas Islands, and I love that all equipment is provided and the group stays small with a max of 7 people. It’s a short outing (about 4 hours) built around getting you into the water with real guidance and an easy pace.

One caution worth planning for: you’ll complete a health questionnaire and going underwater within 48 hours of flying isn’t recommended. The crew, led by Sebastian Briones, is great at helping people feel ready, and an instructor like Leila can be especially reassuring—but the safety screening still decides who gets in.

Key things I’d circle on your itinerary

• Two underwater sessions so you’re not paying just for one short moment in the water
• Gear included (so you’re not hunting rentals or extra costs last-minute)
• Small-group feel (max 7) for more personal attention from the guide
• Boat transport plus round-trip transit from Sayulita keeps the logistics simple
• Marietas biodiversity guided by geography that’s famous thanks to Jacques-Yves Cousteau

Sayulita to the Marietas Islands: the “easy out” factor

If your Sayulita trip plan includes getting offshore without turning it into a full production, this outing nails the basics. You meet at C. 1O de Mayo 2, 63728 Sayulita, Nay., Mexico with a 9:00 am start, and you end back at the same meeting point. That matters more than it sounds. With a tour like this, you don’t want to spend your morning figuring out what boat to chase.

This is also a time-efficient way to access the Marietas area. In roughly 4 hours, you’ll cover the boat portion, reach the key spots around the islands, and complete two underwater sessions with a professional guide. The operator keeps the group size tight (up to 7 people), which usually means you get better attention on gear checks, buoyancy cues, and where to look when the underwater life shows up.

One more practical note: the experience is offered in English, and you’ll receive a confirmation at booking. If you’re the type who likes to lock things in early, it’s commonly booked about 28 days in advance, so earlier planning usually helps.

What you get (and why it’s good value): equipment, guide, boat, and two water sessions

At $195.71 per person, the price looks like a “tour price,” not a bargain. But here’s the value angle I’d watch: you’re paying for the total package that’s hard to DIY—boat access, pro guidance, and the gear.

Here’s what’s included:

• Professional guide
• Use of dive equipment (all gear provided)
• Boat transport
• Bottled water
• Two underwater sessions

What’s not included is simpler: souvenir photos are available to purchase.

When equipment is provided, you avoid two common headaches: bringing the wrong size stuff and paying extra on top. When boat transport is included, you’re not left trying to coordinate with multiple parties or guessing timing. And two underwater sessions mean you’re not just “trying it once” and hoping for the best.

If you’re comparing against booking gear separately and paying for boat access separately, this kind of bundle is usually where you come out ahead.

The briefing before you go underwater: making nerves feel normal

This is one of those experiences where the people side matters as much as the marine side. In the feedback I reviewed, the standout theme was reassurance—especially for people returning after time away.

For example, Sebastian Briones is credited with helping people settle before they descend, and instructor Leila is praised for passion and clarity. That doesn’t mean you’ll be pushed past comfort. It means you’re likely to get a real walkthrough: gear setup, how to handle the water, and what to expect once you’re under.

You also have to complete a health questionnaire. Some pre-existing conditions—like asthma or heart conditions—may prevent you from going underwater. Also, you’re advised not to do this if you recently flew: 48 hours after flying isn’t recommended. If you’re even slightly unsure, I’d treat the health steps as part of planning, not a surprise on the day.

If you’re moderately fit and ready to follow instructions, you’re in the sweet spot for a smooth experience.

Bay of Banderas (Stop 1): where the trip turns from land to ocean

Your first stop is the Bay of Banderas. This isn’t just a “transfer point.” It’s where you get the ocean context: water conditions, boat pace, and the immediate rhythm of the day.

Expect a combination of boat time and short outlook moments while you’re heading to the more focused island areas. This is also where the guide’s job starts to click for you: they’ll set expectations for visibility, where to look, and what kind of life you’re likely to see. In the experiences people shared, guides talked a lot about fish and birds—so you’re not only staring at the water while waiting. You’re learning what you’re actually looking at.

A practical drawback to keep in mind: bay conditions can shift. Even when the plan is solid, the ocean has its own schedule. The tour is weather-dependent, and if conditions are poor, you may be offered a different date or a full refund.

Punta de Mita (Stop 2): the coastline route that frames the day

Next up is Punta de Mita. Since this is a stop on the way to the island area, it helps more than you might think. You’re moving along a coastline that gives you a sense of geography—where the land ends, where the open water starts, and how the islands sit in the bay.

This stop also helps you transition mentally. After time on the surface, you’ll be ready to focus on the underwater part when the team moves you into the key site around the islands. If you’re someone who gets anxious underwater, this staged pacing can help. You’re not rushing from parking lot to full focus in one minute.

The tradeoff is simple: you’re still on a schedule. If you hate waiting around, this may not feel like “constant action.” But it’s the waiting that makes the later underwater time better—calm setup, organized gear checks, and fewer last-second changes.

Marietas Islands (Stop 3): the main attraction for beginners and experienced swimmers

This is the stop you’re really paying for: the Marietas Islands. These islands are known worldwide due to Jacques-Yves Cousteau, and they’re famous for biodiversity and distinctive geography. For you, that translates into a higher chance of seeing varied marine life, not just one predictable “same stuff, different day” scene.

What I like about the way this experience is positioned is that it’s meant to work for different comfort levels. The Marietas area is described as a favorite destination for both beginners and advanced participants, largely because the geography and marine life can support different styles of underwater exploration.

In the feedback I reviewed, people highlighted sightings like fish, eels, and even an octopus. Bird life also came up, including blue-footed boobies. Even if you don’t see every exact animal every time, the point is that the ecosystem is active.

A realism check: you can’t control visibility or water movement. If the sea is rough, it can affect how you feel underwater and what you can spot. That’s why the “check-in and safety screening” steps matter. They’re not there to slow you down. They’re there to keep the experience enjoyable.

Oceano Adventures (Stop 4): where the operation runs smoothly

The last stop is Oceano Adventures. In a day like this, that usually means the operation ties together: the staff coordinates the group, manages gear, and keeps the timeline on track so you get back to your meeting point without chaos.

This matters because you’re doing two underwater sessions, and you want to avoid the common problem of being late, rushed, or underprepared. A well-run final stop usually means you’re finishing the day as cleanly as it started—organized, accounted for, and ready to head back to Sayulita.

Also, since everything ends back at the meeting point, you don’t have to solve what to do next while your energy level is dropping. You finish, you’re done, you go eat something excellent.

Price and logistics: what $195.71 really covers

Let’s talk money like adults.

You pay $195.71 per person, for about 4 hours total, with:

• boat transport
• a professional guide
• all equipment provided
• two underwater sessions
• bottled water

Souvenir photos are extra.

So what are you not paying for? You’re not paying for gear rental. You’re not paying for a separate boat arrangement. You’re not paying for a guide from scratch. You’re paying for a packaged day built around getting you to a specific marine area and keeping you safe enough to enjoy it.

For value, I’d also think about your time. If you’re already in Sayulita, a day tour like this saves you the mental load of planning access to the islands. And the small-group cap (max 7) is part of why the operation costs what it costs. More personal attention takes space.

If you’re doing it on a tight schedule, booking in advance also helps. With many departures scheduled and fewer spots per day, earlier planning gives you better odds.

Who should book this Marietas underwater session?

This tour is a good fit if you:

• Want a guided, gear-included way to experience the Marietas area
• Prefer small-group attention
• Like clear structure: two underwater sessions, a professional guide, and a short total time commitment
• Are willing to follow safety steps and complete the health questionnaire

It’s also workable for people who are a bit nervous. The reassurance theme (including examples with Sebastian Briones and instructor Leila) is a strong sign that the team helps you feel prepared before you go under.

Who should reconsider? If you can’t meet the health requirements, have a medical condition listed as a possible barrier (like asthma or heart conditions), or you can’t follow the timing rule about 48 hours after flying, this probably won’t be the right day for you.

And kids: children must be accompanied by an adult. That’s essential for families planning their day.

Practical tips to make the day smoother

These are the things that usually make or break a coastal tour day.

• Bring your calm. Even if you’re excited, take a breath during the gear setup. It helps the team help you.
• Plan around your body. The tour asks for moderate physical fitness, and the health questionnaire is mandatory.
• Don’t fly right before. If you’ve got air travel in the last two days, rethink the schedule.
• Use the water time wisely. With two underwater sessions, you’ll get more value if you relax and stay focused on your guide’s cues.
• Expect weather checks. Good weather is required. If it changes, you’ll be offered another date or a refund.

If you’re pairing this with other ocean activities, this area is also known for snorkeling options in the Marietas zone. One person specifically mentioned a second day of snorkeling that included entering the Hidden Beach. If you’re curious about that side of the experience, ask the operator what’s available for your dates—without assuming this scuba session includes it.

Should you book this Scuba Marietas Islands experience?

If you want the Marietas Islands experience without wrestling logistics, I think it’s a solid yes. The strongest reasons to book are simple: gear provided, small group size, and two underwater sessions with a professional guide. Add in the fact that it’s timed for an easy return to Sayulita, and it becomes a practical day, not a headache.

I’d book especially if you’re returning to the water after time off or you want reassurance and structure. The Sebastian Briones and Leila examples in the feedback fit that vibe.

Just make sure your body and schedule match the safety rules. If the health questionnaire flags an issue, or if you flew within 48 hours, don’t force it. The ocean is big, and it’ll still be here when you’re cleared.
