Scuba Diving Puerto Vallarta Undersea Arcos or Marietas
Dolphins and scuba in one Puerto Vallarta morning. I really like how the team stays patient when you’re learning, and how they set you up so you’re not wrestling gear all day. One thing to keep in mind: water visibility at Los Arcos can vary, and on less-clear days the underwater view may feel more muted.
This outing works because you get a full day mix—wildlife from the boat, a warm-up at the Islas Marietas area, then underwater time at Los Arcos National Park. It’s also a tight group (max 14), which usually means more help when you need it.

Why This Puerto Vallarta Scuba + Marietas Combo Is Worth It

If you want a Puerto Vallarta day that feels like more than just a checklist, this route is smart. You’re out of the marina around 9:00 am, you spend meaningful time in the water, and the boat rides have a real “look up and scan the water” vibe.
My favorite part is the balance: Marietas is where you get the snorkel learning and the chance of headline wildlife, while Los Arcos is where the underwater experience is built around practical depth options for different experience levels. The staff names show up again and again too—people specifically call out Carlos, Eric, Nahum, Martin (captain), and Rodrigo for keeping things smooth.
And yes, you’ll pay extra only if you choose the optional hidden beach activity.
Key Highlights to Know Before You Go

- Hands-on setup from the start: expect help with equipment so you spend less time fiddling.
- Small group feel: up to 14 travelers, not a crowded scene.
- Two different underwater environments: Marietas time centers on snorkeling instruction, Los Arcos is about scuba at depth.
- Wildlife along the route: chances for dolphins, turtles, manta rays, and even whales depending on season and conditions.
- Optional hidden beach with a deposit warranty: extra cost, plus a refund if you can’t access it due to availability or weather.
- Depth options at Los Arcos: from about 20 ft for practice through a much deeper wall for technical profiles.

Starting at Marina Vallarta: The Morning Rhythm (and Why It Matters)
You meet at Marina del Rey Condominium, Proa 22, Marina Vallarta, and you’re set to depart around 9:00 am. That timing is more than convenient—it gives you good odds of calmer seas and clearer morning light for both wildlife spotting and photos.
Before you even hit the main stops, there’s a quick “hey, look at that” moment around the Ameca River area, described as about 10 minutes after leaving. If dolphins are in the mood, this is a chance to see them before you’re even in snorkel mode.
Also, the boat ride is part of the experience. You’re not just being transported. In the winter season especially, conditions can bring dolphins, turtles, manta rays, and whales while you travel out and back. So if you tend to rush, you’ll want to slow down and watch the waterline.
Stop 1: Islas Marietas and the Snorkel Lesson That Actually Helps

Marietas is where this trip starts to feel special because it’s built around learning in a natural setting. After you arrive, you get snorkel gear and hands-on help with using it, plus life jackets and guidance focused on improving your in-water comfort.
This is a smart approach for most people. If you’ve snorkeled before, it still helps because it gets you thinking about breathing, positioning, and staying relaxed. If you’re new, the instruction reduces the two classic problems: panicky breathing and drifting too far from the group.
What you should expect in the water
The plan is built around fun and safety, not speed. You’ll be taught how to use the snorkel equipment and then put it to work in the local waters. Your actual “time under water” depends on conditions, but in one December outing, people reported being down about 45 minutes each time and going roughly 40–50 feet on their underwater sessions (for those doing the scuba portion).
The hidden beach option: $25 and a real refund promise
There’s an optional extra called the hidden beach activity. It’s described as visiting one of the top ten beaches in the world, and it costs $25.00 extra.
What I like here is the deposit approach:
- You pay a deposit cash during check-in.
- If access doesn’t happen due to availability or weather, they say they’ll return your deposit.
- They claim 99% of visitors can get in without problems.
That matters because the hidden beach is the kind of place where conditions can change. Paying extra is a gamble sometimes. Here, they’re at least reducing the sting if you can’t make it in.

Stop 2: Los Arcos de Mismaloya National Park and the Depth-First Design

Los Arcos is the part of the day that’s more “scuba-focused.” You’ll visit Los Arcos National Park, and the site is set up to work for different skill levels.
The details matter:
- It’s described as suitable for beginner practice and also for experienced scuba participants.
- You can find options around 20 ft for practice and certifications.
- There’s also a deep wall route described at around 1600 ft for technical profiles.
Why Los Arcos is a good match for mixed groups
In a mixed group, not everyone wants the same kind of underwater experience. This park layout helps because the trip can steer you toward what fits your comfort level. If you’re new, you’re not forced into the deep end right away. If you’re experienced, you still have something to aim for.
A practical heads-up about visibility
One clear caution shows up in real-world outcomes: water clarity at Los Arcos can be hit-or-miss. One person reported murkier conditions and felt there wasn’t much to see. Another trip day was very clear, with visibility around 30 feet and lots of marine life.
So go with flexible expectations. You’re there for sea life and the experience, not a guaranteed “show aquarium” view every minute.
Wildlife Encounters: Dolphins, Whales, and Friends on the Way

The wildlife angle isn’t marketing fluff here. The route is designed around open-water chances, and multiple outcomes point to real sightings.
From the provided info, you’re in the running for:
- Dolphins
- Whales (humpback whales are specifically mentioned by one solo traveler)
- Turtles
- Manta rays
One of the most memorable moments described is an intense dolphin viewing during the return boat ride—people saw pods moving through the area. Another person highlighted hearing humpback whales on their first trip.
If seeing marine life is your main goal, this tour format makes sense. You’re not stuck staring at one spot all day. You’re moving through habitats where animals tend to show up.
The Team and Instruction Style: What Makes People Relax

What keeps this from feeling generic is the human factor. People specifically praise named guides and the captain for being present and helpful throughout the experience.
A few names you’ll hear repeatedly:
- Carlos: described as there the entire time to help when needed.
- Eric: repeatedly praised for being patient, descriptive in pre-water talks, and making first-timers feel comfortable.
- Nahum: praised as excellent during one Marietas-focused day.
- Martin: credited as captain with a smooth, enjoyable boat experience.
- Rodrigo: mentioned as part of the on-the-ground guidance.
Even if you’re confident, pre-water talk quality matters. It shapes your breathing, buoyancy, and confidence. One first-time participant said the hardest part was mental at first, then everything clicked once they went underwater and stayed calm.
If you’re nervous, you’ll probably appreciate this approach. The instruction is clearly geared toward safety and reducing stress, not just moving people through checklists.
Equipment, Comfort, and Small “Bring This” Notes

The tour includes:
- Life vest
- Boat ride
- Box lunch
- Bottled water
- Scuba equipment (including scuba gear)
- Fees and permits including CONANP and park permits
If you want to save time, you don’t need to bring much beyond what’s listed for comfort. In one trip, people only brought masks and were offered help if they needed more.
Clothing and temperature
Even when it’s warm, sea breezes and water temp can be a factor. One person noted the water felt a bit chill and mentioned the guide offered an extra wet suit. So if you run cold, bring swimwear plus a layer you can keep dry until you gear up.
Also, the tour mentions a moderate physical fitness level as the baseline. If you have heart disease or back/spine/knee problems, it’s not recommended. And if you’re under the influence of alcohol or drugs, participation isn’t allowed.
Price and Value: What $125 Really Covers (and What Costs Extra)

At $125.00 per person, the price is covering a lot of the “hard parts” that often surprise people on the coast: permits, federal fees, conservation donation fees, and the equipment itself.
Included costs you won’t have to chase:
- CONANP (Federal gov) fee
- Conservation donation fee to Bahia Unida
- National park permits
- Equipment and boat time
- Lunch and water
Not included (and when you should plan for it)
Two add-ons show up in the details:
- Beginner scuba class costs $25.00 per person
- Government fees are listed as $6.00 per person
So the realistic math might look like:
- $125 + $25 (if you need the beginner lesson) + $6 government fees
If you already know your way around scuba, you may avoid the beginner class fee. If you’re new or shaky, plan for it—because more instruction time often means a better day.
Timing and the 4–6 Hour Reality
The duration is listed as 4 to 6 hours. In at least one real-day report, people returned around 2:00 pm after departing at 9:00 am, which lands you in the middle of that range.
What you’ll feel during the day:
- You’ll spend time in transit from the marina and then between activity zones.
- You’ll get instruction and then actual water time at each stop.
- Lunch is provided, so you’re not stuck hunting food at sea.
If you’re planning the rest of your day, I’d treat this like a half-day with a buffer. Even when everything goes smoothly, water and wildlife timing is nature’s call, not yours.
Who This Is Best For (and Who Might Want Another Option)
This tour is a good fit if:
- You want a Puerto Vallarta day that mixes snorkel instruction + scuba underwater time.
- You like wildlife and are happy to spend time scanning the ocean from the boat.
- You’re fine with changing conditions, especially visibility.
It can work for mixed experience levels thanks to the way Los Arcos is described (practice depths around 20 ft plus options for deeper technical routes).
Skip it if you’re not a match physically or medically
Based on the rules:
- Not recommended for heart disease
- Not recommended for back, spine, or knee problems
- No alcohol or drug influence
If you’re borderline on fitness, you’ll want to be honest with yourself before booking. You don’t want your day to become a negotiation with equipment and stairs and getting on/off the boat.
Should You Book This Puerto Vallarta Undersea Day?
If you want a day that feels efficient and alive—boat wildlife plus structured in-water help—then yes, this is a strong option. I especially like the combination of small group size, real instruction from named guides like Eric and Carlos, and the fact that you’re not locked into one type of water time all day.
Book it if:
- You’re excited about dolphins/whales/turtles chances.
- You want scuba support without feeling thrown in at the deep end.
- You’d like an optional hidden beach upgrade with a deposit refund if access is blocked.
Think twice if:
- You’re expecting perfect visibility every time at Los Arcos.
- You’d rather avoid extra costs—because beginner instruction and the hidden beach option can add on.
If you line up with those points, this tour is a good value way to experience Banderas Bay’s underwater world without making the day complicated.
