Marietas feels like a postcard underwater. This half-day scuba tour from Sayulita takes you into Banderas Bay, then out toward the Marietas Islands, where the water life and rock formations make every minute feel hands-on. I love that the equipment is provided, so you spend less time sorting gear and more time staying relaxed. I also love the small group size, which means you get real attention when you need it.

The one thing I’d plan around is your comfort with the safety checks. You’ll complete a health questionnaire before you go, and some medical conditions may mean you can’t participate. If you want a certified session, you’ll need proof of scuba certification, so bring the documentation you rely on at home.

Key things I’d mark on your map

• Small group limit (max 7), so the guide can correct your position and buoyancy without rushing you
• Round-trip transit from Sayulita, which keeps the whole day from feeling like a logistical scavenger hunt
• All scuba equipment included, plus bottled water, so you pack lighter
• Two underwater sessions, not just one short splash-and-go
• Guided route through Banderas Bay and Punta de Mita, leading into the Marietas area

Marietas Islands from Sayulita: why this spot works

If you’ve been to the coast and thought it was pretty, Marietas changes the game. This area is known for serious marine life and for underwater geography that gives you something to look at besides fish, even when visibility shifts. It’s also part of why the islands gained worldwide fame through Jacques-Yves Cousteau. People talk about the Marietas because the place is built for exploration, not just sightseeing from a boat.

What I like about starting from Sayulita is that you get access without the long travel headache. You’re not trying to coordinate multiple transfers on the road. You board near the start point, head out, and come back to the same meeting area at the end. For many people, that simple rhythm matters more than you’d think.

Also, this kind of site is useful for a broad range of comfort levels. The Marietas environment can support both first-timers and more experienced participants, since there’s a lot to see and the team can shape what you focus on. That’s a practical advantage if your group has mixed comfort levels.

Price and what $195.71 really covers

At $195.71 per person, this isn’t a bargain price, but it isn’t just you renting some gear and hoping for the best either. Here’s what you do get: professional guide, boat transport, use of dive equipment (equipment is included), and bottled water, plus two underwater sessions.

When I look at value, I care about what can silently add up: rentals, staff time, boat fees, and the parts of the day that turn into stress. This tour packages those basics for you. If you’ve ever tried to piece together a coastal day with separate rentals and separate boat arrangements, you know how quickly the cost climbs.

What’s not included is also clear. Souvenir photos are available to purchase, but they’re not part of the base price. If you like to buy photos as a keepsake, plan to budget a little extra.

One more quiet value point: the tour runs around 4 hours and starts at 9:00 am. That timing helps you avoid burning an entire day, and it can also keep the schedule smoother if weather shifts later.

The route: Banderas Bay, Punta de Mita, then Marietas Islands

This is a boat-based outing with multiple stops. Each one has a job, and the flow matters if you want a day that feels steady rather than chaotic.

Stop 1: Bay of Banderas

The Bay of Banderas is your starting point, and it’s where you get the day into gear. I’d expect the team to set expectations here, so you know what to do before you’re fully committed underwater. It’s also a good area for getting oriented to the water and the boat routine, especially if it’s been a while since you last did a scuba session.

The potential drawback is simple: you’re still getting started, so if you’re prone to getting nervous, this is where your nerves may peak. The best way to handle it is also the easiest: ask questions early, and don’t pretend you understand everything when you don’t.

Stop 2: Punta de Mita

Punta de Mita is a second step toward the main islands. Think of it as a transition point in the scenery and conditions you’ll experience. This stop can also help break up the day, so you don’t feel like you’re just sitting on the boat until the main event.

The main thing to be ready for is motion and sun. You’re moving around by boat, and the schedule is tight enough that you’ll want to hydrate and protect yourself from sun exposure.

Stop 3: Marietas Islands

This is the reason you came. The Marietas area is known for strong biodiversity and for the kind of underwater geography that keeps you looking around. Even if you’re not a total marine-life nerd, the rocks and the layout give you a natural path for your attention.

From what I’ve seen work best, your enjoyment goes way up when you stop trying to force exact sightings and instead let the guide point your focus. You’ll likely see lots of fish and other sea life, and the general experience can feel both beginner-friendly and interesting for people with more experience.

Stop 4: Oceano Adventures (end of the activity)

The final listed stop is Oceano Adventures, and then the activity ends back at the meeting point. For planning, treat this as a wrap-up period where you transition back to land and get out of gear.

I like having the return tied to the same meeting point, because it reduces the odds of confusion. You’re not trying to find your way around unfamiliar streets while you’re wet, tired, and hungry.

What the two underwater sessions feel like

This tour includes two underwater sessions, and that matters. One session can be great, but it’s also short. Two sessions give you a chance to settle in, then actually enjoy the second one with more confidence.

In one account I read, the team reassured someone who hadn’t done a scuba session in over five years. The key detail for your planning is not the time gap itself, it’s the approach: the guide went over everything in a calm way before going in. If that’s you, bring your questions to the surface. Ask what you should focus on, what to do if you feel off-balance, and how the guide communicates underwater.

Wildlife and moments to expect

The Marietas area is associated with a wide mix of underwater life, and you’ll often hear about encounters with fish like eels and octopus. Birds are part of the picture too, including blue-footed boobies, which you may spot while you’re on the water or near the activity areas.

Even when you do not see a specific animal, the underwater geography usually keeps the experience satisfying. If you want the best odds for enjoying what you see, go in thinking about behavior, not just species names. Watch how things move, how fish react to current, and how the guide positions you for a better look.

Conditions: warm water in season

One review highlighted warm water in September. You might find similar comfort depending on the month you go, which makes a real difference for first-timers. Warmer water means you can concentrate on technique instead of just trying to stay comfortable.

Still, conditions change day to day. If you feel chilled easily, bring whatever you’re normally comfortable with in similar temperatures, and don’t assume it’ll feel like a beach swim.

Guides, gear, and the small-group advantage

A tour is only as good as the people running it, and in this case the human factor shows up in the details. I saw praise for friendliness, accommodating attitudes, and instructors who explain things clearly.

Sebastian Briones is listed as the experience provider. One review specifically called out Sebastian for reassuring a nervous participant and walking through the process so they felt ready before descending. That kind of confidence-building matters. It turns a scary first minute into a manageable start.

There was also mention of Leila as the dive instructor/guide, described as passionate about the ocean and wildlife both on land and in the sea. You can feel the difference when the guide cares. Not just because they know names of animals, but because they guide your eyes better. That’s how you end up remembering the trip, not just checking a box.

Equipment included means fewer points of stress

You get use of dive equipment with the tour. Translation: you avoid the most common day-ruiner, which is discovering the rental mask doesn’t fit or the regulator feels off after you’ve already committed.

You still should expect basic fitting and setup time, so don’t rush that part. If something feels wrong, speak up before the team starts counting down to the first underwater session.

Small-group size, real attention

With a maximum of 7 travelers, the guide can watch everyone instead of herding people. That’s valuable if you want corrections on buoyancy, if you need help with comfort, or if you’re simply trying not to drift into the wrong place.

If you’ve ever done a big group outing, you know what I mean: you spend the time searching for the guide. Here, the odds are better that you’ll know where to look and how to respond.

Safety, health questions, and planning around flights

This tour includes a health questionnaire prior to your scuba session. Some pre-existing medical conditions, like asthma or heart conditions, may prevent you from diving, and the operator notes that you should have moderate physical fitness.

I always recommend being honest here. It protects you and it protects the group. If you’re on the fence about whether you should participate, ask your doctor before you go. If you wait until the day of, the outcome can be stressful.

Timing and flying

They also note that doing a scuba session within 48 hours of flying is not recommended. That’s one of those travel details that seems minor until you realize your itinerary might accidentally put you in the danger zone for pressure changes. If you can, schedule your Sayulita water day with breathing room before or after flights.

Alcohol policy is strict

The operator reserves the right to refuse service to passengers who are intoxicated or show signs of intoxication, and if the tour is canceled for that reason, there’s no refund. It’s a reminder that this is run as a safety-first activity, not a party cruise.

What to bring, and what to skip

The essentials come down to comfort and basic safety.

Bring:

• Your confirmation details on your mobile ticket
• Proof of your scuba certification if you plan to participate in a certified session
• A way to handle sun and wind on the boat, since you’ll be out for several hours

Skip:

• Big hopes of buying nothing extra. Souvenir photos are available to purchase, but they’re not included, so you either budget for that or accept that your memories will be your main keepsake.

Also, plan for children to go with an adult. The tour states that children must be accompanied by an adult.

Who this Marietas Islands scuba tour suits best

This outing fits best if you want a guided Marietas experience without turning your day into a logistics project.

You’ll likely be happiest if:

• You like having equipment provided
• You want a small-group experience with individual attention
• You want two underwater sessions in a single half-day plan
• You’re comfortable completing a health questionnaire and following safety guidance

It may not be the best choice if:

• You have a medical condition that could disqualify you based on the questionnaire
• You’re traveling with flights that land you within 48 hours of the water session
• You want a purely casual, no-instruction kind of outing. This tour is guided and safety-focused, so you’ll need to pay attention and follow directions

Should you book? My practical take

Book it if you want a well-run Marietas day that includes the gear, gets you there with round-trip transit from Sayulita, and gives you two underwater sessions in a max 7 group. I especially like the combination of included equipment and the reassurance-style guidance people have described, including Leila and Sebastian.

Don’t book it if you’re expecting zero safety paperwork or if your health situation might be a question mark. If the health questionnaire could be a problem, sort that early rather than hoping it works out.

If you do book, arrive ready to ask questions, listen closely, and treat the first minutes as setup time. That’s the difference between a nervous start and a trip you remember for the right reasons.
