Scuba Diving Marietas Islands

The Marietas Islands around Banderas Bay are one of those rare places where the water life is serious and the scenery is photo-ready, from the surface down. This tour is built for hands-on learning and confident exploring, with two underwater sessions and round-trip transport from Sayulita.

I especially like the all-gear-provided setup, because you can show up with no extra equipment stress. I also like the small group size (up to 7), which usually means you get real attention and not just being handed a plan and a regulator.

The main thing to consider is that this experience is weather and health dependent. You will need to fill out a health questionnaire, you may be turned away if conditions are not safe, and you should not plan to do this within 48 hours of flying.

Key highlights you should care about

• Two underwater sessions with the gear included, so you spend less time preparing and more time in the water
• Up to 7 people max, which helps the guide manage buoyancy, comfort, and pacing
• Round-trip transport from Sayulita, so the day feels easy to manage
• Banderas Bay plus Marietas Islands, an efficient route to see both open-water scenery and the island area
• Real coaching from Sebastian Briones, plus Leila as an instructor/guide (from guide performance seen in past experiences)

Marietas Islands and Banderas Bay, the mix that works for many skill levels

If you are choosing between doing just one kind of water day in the Sayulita area, this route is a smart mix. You get boat time on Banderas Bay, then you move into the Marietas Islands zone, where the geography and habitat tend to create strong wildlife viewing chances and great underwater visibility on good days.

What makes this trip especially interesting is that it suits a wide range of comfort levels. The islands are known worldwide for their biodiversity and the way currents, rock, and open-water edges can shape what you see. That is why you will find people starting out, plus experienced divers, all sharing the same water area under the guidance of the crew.

There is also a practical advantage here. Even if you do not consider yourself a hardcore ocean person, you will still enjoy it because you will get direct coaching, gear support, and a clear plan for when you get in and when you come back. You are not expected to figure everything out alone.

What you actually get for $195.71, and why it is not just a ticket

At around $195.71 per person for about 4 hours, this is not an “air-only” excursion. The value is in what is included: a professional guide, two underwater sessions, use of dive equipment, and boat transport, plus bottled water.

Here is what that means for your day, in plain terms. First, you do not need to hunt down rental gear or deal with last-minute sizing. Second, boat transport is handled, so you spend your energy on the water, not on logistics. Third, two underwater sessions typically give you enough time for one session to feel like a warm-up and the second to feel like you are settling into the day.

The only item not included that you might care about is souvenir photos, which are available to purchase. That is a common add-on, but it is not built into the core price, so you can decide later if you want them.

My other value note: the tour runs with a maximum of 7 travelers. When you compare that to larger groups in the same region, the smaller number is often what makes coaching feel personal.

Sayulita to the water: the boat ride and how you should prep

Your day starts in central Sayulita at C. 10 de Mayo 2, 63728 Sayulita, Nay., Mexico, with a 9:00 am start. The experience ends back at the meeting point, which is how you want it to feel when you are on a short, half-day schedule.

Between the dock and the dive sites, expect a mix of cruising and getting briefed. This is where good operators shine. You should listen closely to how your guide explains entry, signals, and what to focus on during the session. Even if you have done scuba before, review matters. Conditions can change from day to day in Banderas Bay.

Quick prep tips that make a difference:

• Bring a small bag for your phone, since you will want it dry.
• Use reef-safe sunscreen if you have it, because you will likely be out in daylight before and after the sessions.
• Wear something comfortable under your gear. You want it to still feel decent after you are back on land.

You also want to be realistic about comfort. This tour notes moderate physical fitness as a requirement, so plan for some walking and getting in and out of the boat area.

Stop 1: Bay of Banderas, where the scenery and marine life come together

The Bay of Banderas segment is your first taste of the day. This is the part that sets the tone, because you usually get your first chance to settle into buoyancy, breathing rhythm, and staying relaxed.

Even without going too technical, Bay of Banderas can be a great place to spot marine life because the water tends to offer a balance between open viewing and interesting underwater edges. A common pattern on these trips is that you see more than you expected once you stop thinking about technique and start watching what is around you.

In past experiences in this region, people have reported seeing plenty of wildlife like fish, plus surprises such as eels and even an octopus. You are not guaranteed sightings, but the point is that the area has a reputation for that kind of variety, and your guide will help you notice it.

What to watch for as you go down:

• Slow movements. The calmer you are, the more likely you are to see active animals.
• Buoyancy control. It affects where you look and how much the bottom or rocks get stirred up.
• Your guide’s pacing. If your guide keeps it steady, it usually means everyone is comfortable and no one is rushing.

Stop 2: Punta de Mita, a shift in geography and viewing style

When the day moves toward Punta de Mita, you are shifting zones. That matters because marine life often responds to how water flows over depth changes and coastal features.

This is usually where you start to feel the difference between the “first session nerves” stage and the “I can actually pay attention” stage. If your first underwater time was about settling in, Punta de Mita can feel like a step into the fun part of the day, where you spend more time watching and less time thinking about the basics.

A key benefit here is the instruction style. One past experience highlighted how the guide team made even someone who had not been underwater in years feel comfortable. That kind of reassurance is not fluff. It changes your whole body tension level, and that makes the session better for you and easier for everyone around you.

Stop 3: Marietas Islands, the postcard area with real biodiversity

The Marietas Islands are the reason many people plan their whole Sayulita trip around this region. The islands are widely known for biodiversity and the way the underwater terrain shapes what you can see.

On the surface, they are famous for their look. Underwater, they are often about variety. The rock structure can create visual variety at different depths, and currents can bring life into view if conditions are right.

Even if you are mostly here for scuba sessions, it helps to understand why the Marietas have a reputation beyond underwater. This area is also known for snorkeling opportunities, and it is often talked about in relation to Hidden Beach. On some days and with the right schedule, you might connect to that wider idea of the islands as a whole. For this particular experience, your focus stays on the water sessions, but the setting is part of the magic.

One practical thing: Marietas conditions can vary with weather. That is why this kind of tour is a good match for people who can be flexible. If conditions do not cooperate, your operator may switch dates or offer a refund.

Stop 4: Oceano Adventures and what the wrap-up usually feels like

After your final underwater session, you will head back toward Oceano Adventures as part of the day’s flow and then return to the meeting point in Sayulita. The wrap-up is not just paperwork. It is usually when you get final questions answered and check how everyone feels after the water time.

This is where you can also decide if you want to do additional water activities later in your trip. In the same operation ecosystem, some people have done both scuba and snorkeling on back-to-back days, and they found the combination worked well because snorkeling helps you enjoy surface viewing and the scuba sessions add the underwater perspective.

If you are someone who gets tired after water activities, plan the rest of the day lightly. You will likely want an easy meal, a slow walk, and time to decompress.

Two sessions, equipment included: how to make the most of your time underwater

Two underwater sessions can be a sweet spot on a half-day schedule. It means you get a chance to do the basics well in session one, then bring that confidence into session two.

Because equipment is provided, you should still take a moment to check how everything fits. Ask for adjustments right away if something feels off. A calm, correct fit reduces fatigue and makes it easier to stay relaxed.

Also, pay attention to the way your guide communicates. In past experiences, the crew included a reassurance approach that helped people who were nervous, including someone who had not done this in over five years. That is a good signal that the guide team is tuned to comfort, not just performance.

If you are certified and you want a certified session, the operator requires proof of your scuba certification. If you do not have that proof, your participation may be limited to what your operator can support under their rules.

The guide impact: Sebastian Briones and Leila’s coaching style

This is one of the most highly praised parts of the experience. Sebastian Briones is listed as the provider, and in one standout account, the scuba instructor/guide Leila was described as phenomenal, with a strong passion for diving and ocean life.

What does that mean for you? It means you can expect more than check-the-box safety talk. You are likely to get bird and fish explanations, and you will probably learn how to look for wildlife in a way that makes the underwater time feel richer.

There is a difference between knowing what to do and feeling safe enough to enjoy doing it. The best guide teams handle both. They slow you down when needed, and they keep you moving when it is safe and appropriate.

And that is why this tour earns a 4.7 rating from 107 reviews, with 93% recommending it. The scoring is not just about the locations. It is about how the day feels in the water with real people.

Safety and health rules you should treat as part of the experience

This operator is clear about safety, and you should treat the rules seriously, even if you feel totally fine.

You will be required to complete a health questionnaire before diving. Certain pre-existing medical conditions, such as asthma or heart conditions, may prevent you from participating. If you are not sure how your situation fits, it is worth checking before you book so you are not stuck with a disappointment.

The tour also notes:

• Diving within 48 hours of flying is not recommended.
• The operator can refuse service if someone is intoxicated or shows signs of intoxication, and that can affect refunds.
• Children must be accompanied by an adult.

What I recommend for you, to avoid last-minute stress:

• Answer the health questionnaire honestly.
• If you recently flew, add buffer time. Your body needs time to adjust.
• If you are bringing a child, plan for adult supervision throughout the day.

Weather dependence and how to keep your day flexible

Because this is water-based, good weather matters. If conditions are not suitable, the tour may be canceled and you will be offered a different date or a full refund. That is the right approach for safety, and it also means you should keep your schedule flexible on the day you pick.

If you are booking early, that is smart. This trip is commonly booked about 28 days in advance. Popular half-day tours in Sayulita tend to fill up, especially ones with small-group limits.

Who should book this Marietas scuba sessions tour from Sayulita

This tour is a good fit if you want:

• A guided water experience with equipment provided
• A small group and personal attention
• Two underwater sessions in a short time window
• The combination of Banderas Bay scenery and the Marietas Islands area

It is also a solid choice for mixed experience levels, because the operator’s focus on coaching and comfort helps both first-timers and returning divers.

Where you might hesitate:

• If you have medical concerns, check eligibility based on the health questionnaire requirements.
• If you are not comfortable with moderate physical activity, the boat day might feel more challenging than you want.

If you want a full ocean day, this half-day works well as your first or second water activity. People often pair it with snorkeling so they get both surface and underwater perspectives.

Should you book it or look at something else?

Book this if you want a guided, gear-included scuba day that gives you two underwater sessions and a real shot at enjoying wildlife without the stress of logistics. The small group cap and the strong coaching culture from guides like Sebastian Briones and Leila are the kind of details that usually turn a good trip into a memorable one.

You might skip it if your schedule is locked to specific timing right after flying, or if you are uncertain about health eligibility. In those cases, it is better to check first, so your effort goes into a day that can actually happen.

If you are ready to trade long planning for a well-run half-day in one of Mexico’s most famous island settings, this is a very practical choice from Sayulita.
