Picture yourself drifting above a neon-bright reef while parrotfish flash beneath you, or gliding silently through an underwater canyon where an octopus peeks from a crevice. Both moments happen in Banderas Bay, and both are easy to reach—you just choose whether to stay on the surface or dive right in.
Snorkeling keeps you floating face-down, watching the show from just above the surface. Scuba lets you descend into deeper waters, breathing calmly as rays and schools of fish swirl at eye level. Neither option is "better"; the difference is how deep you want your connection with the Pacific to go.
Here we break down what each experience feels like, from first equipment check to final splash, then share our favourite tours so you can plan with confidence. Our team at Vallarta Adventures has spent years guiding travellers through these waters, and we're ready to show you the bay's wild side—at any depth you choose.
Why Banderas Bay Works for Both
Banderas Bay curves like a natural amphitheater, cradling calm water that stays welcoming year-round. Sea temperatures hover between 75 and 85°F, creating a comfort range that means less gear and longer play time whether you're skimming the surface or descending deeper.
The geological story is just as inviting. Volcanic activity left behind towering, barnacle-studded granite formations that create perfect conditions for both activities. At Los Arcos Marine Reserve, the arches and walls act as rocky breakwaters, forming sheltered pools where sergeant majors, parrotfish, and angelfish gather in bright clouds. More than 300 marine species thrive here, with the same rock formations dropping sharply into an abyss—so snorkelers enjoy shallow coral gardens while divers slip along vertical walls only meters away.
Visibility reaches 100 feet in the dry season, especially along the south shore's network of protected coves. These glasslike conditions are perfect for first-timers stepping away from resort pools to experience real ocean adventure.
December through April brings an extra treat. The songs of migrating humpback whales travel through the water column, adding an unforgettable soundtrack for anyone wearing a mask. From surface to seafloor, the bay's overlapping ecosystems make every depth feel like the right depth.
What Snorkeling Is Really Like Here
Slip into the water and you become instantly weightless, face down, legs gently kicking while you breathe easily through the snorkel. The surface cradles you and the Pacific opens below like an endless aquarium.
We love how quickly beginners take to it. A short safety chat, a few minutes practicing the mask seal and you're ready. Kids as young as six often join grandparents in their seventies, because strong swimming isn't required and flotation vests are always within reach. The gear list stays refreshingly light—mask, snorkel, fins. No tanks to strap on, no gauges to monitor. That simplicity keeps your mind on parrot-bright fish rather than equipment checks.
Each session typically lasts thirty to sixty minutes of relaxed water time before a break on deck. Warm bay temperatures keep chills away year round, so hopping in for a second swim feels natural. Each site adds its own flavor: At Los Arcos granite arches rise above and plunge below, sheltering clouds of butterflyfish and the occasional turtle. The protected Marietas Islands offer volcanic rock gardens where schools shimmer in glass-clear water inside a UNESCO reserve. Quiet Majahuitas sits in a calm cove, perfect for newcomers who want gentle waves and easy entry.
With visibility often reaching thirty meters, you get a sweeping top-down view that feels like flying over a reef. From that vantage you can watch rays glide along the sand, spot urchins tucked in crevices, and track a curious pufferfish without ever holding your breath. When you climb the ladder back to the boat, salt drying on your skin, the only question left is how soon you can drop your face back into that blue world.
Going Underwater With Scuba
The first breath from a regulator feels different than anything else. You sink below the surface, bubbles drifting upward while every sound softens. Weight disappears and the reef surrounds you on all sides. You're part of the scene, hovering beside schools of colorful fish and watching marine life glide past your mask.
A single dive lasts about forty minutes, though preparation extends your experience. We help you gear up with everything needed, brief the dive plan, and ensure safety. While equipment might seem heavy on the boat, it feels nearly weightless underwater.
Newcomers begin with a Discover Scuba session featuring short theory and shallow-water practice, while certified divers can dive immediately. All guests complete health questionnaires and observe post-dive safety protocols.
Site selection defines your adventure. Los Arcos features canyon walls where octopuses hide and eagle rays patrol. The Marietas Islands offer caves and the chance to see giant mantas, while experienced divers can explore deeper offshore sites.
Time underwater heightens every sensation. You'll witness marine life up close, feel gentle currents, and experience the peaceful focus of drifting through this silent world.
Making Your Choice
Start with your schedule and comfort level. Snorkeling fits neatly into a morning or afternoon—usually two to five hours including boat transport and gear setup. A single scuba session claims most of the day because training, tank fills, and surface intervals stretch the experience to roughly four to eight hours.
Consider your relationship with the water itself. Surface exploration keeps you face-down where natural breathing feels familiar. Underwater adventures swap that freedom for full immersion, which means regulating buoyancy, equalizing your ears, and trusting compressed air. For scuba diving, beginners need a short "Discover" lesson covering basics, while deeper dives require open-water certification.
Budget follows complexity. Light snorkeling gear costs less, so guided tours generally fall in a more accessible price range. Scuba gear includes tanks, regulators, and buoyancy jackets, pushing costs higher, especially with certification.
Health and age matter too. We welcome surface swimmers as young as six, but underwater explorers must be at least ten, comfortable in water, and free of respiratory or heart issues. Pregnant travelers or anyone flying within 18 hours should stay topside for safety.
Ask yourself what you want today: a quick, flexible glimpse from above, or a slow, silent descent into canyons and caves. Many guests split the difference—trying surface exploration one day, then descending the next—letting every voice on the trip find the depth that feels right.

We know exactly where to find the richest marine life in Banderas Bay. Our PADI-certified guides handle safety briefings, gear, and navigation while you focus on the experience. All you need to do is choose how deep you want to go.
Snorkeling Tours
Marietas Eco-Discovery
You'll cruise to the UNESCO-protected Marietas Islands, where volcanic arches rise above turquoise water. After a thorough orientation, slip in with mask and fins to spot pufferfish, angelfish, and the occasional sea turtle. Between underwater sessions we switch gears—kayaking beside rocky cliffs, watching blue-footed boobies nest, and sharing a beach barbecue. Guides weave in stories about ongoing conservation, so the day balances adventure with insight.
Luxury Sailing
Step aboard our French-built sailing yacht for a more polished approach to marine exploration. Small groups mean we can adjust the itinerary on the fly, anchoring at quiet coves like Majahuitas or Los Arcos for unrushed underwater stops. A gourmet lunch appears from the galley while the premium bar stays open throughout the cruise. With steady breezes filling the canvas and reef fish glittering below, this is our most relaxed way to explore the bay.
Scuba Tours
Diving at Los Arcos
Just south of Puerto Vallarta, granite pinnacles hide a maze of swim-throughs. Beginners start with one shallow dive, while certified divers can add a second tank that drops along the canyon wall where lobsters, octopuses, and eagle rays patrol. We time each descent for the clearest visibility and provide detailed briefings so you know exactly when to watch for a green moray curling out of a crevice.
Las Caletas Diving Lesson
This full-day course is built for first-timers who want formal training without committing to multi-day certification. We start on a sheltered beach at Las Caletas, practicing buoyancy and regulator skills in waist-deep water. After lunch under the palms you advance to an open-water dive where colorful schooling fish and gentle currents make the final exam feel like a reward, not a test.
By the time we motor home you'll understand the basics of underwater breathing and leave with credit toward a future PADI card.
Bottom Line
Surface exploration shines when you want accessibility and flexibility. With minimal gear, you can glide over vibrant reefs, making snorkeling perfect for families, beginners, and those seeking stress-free adventure. The top-down view reveals colorful fish schools, marine patterns, and reef formations in one sweeping panorama.
Underwater adventures reward commitment with immersion. Scuba diving transforms you from observer to participant, allowing close encounters along Los Arcos canyon walls or within volcanic tunnels at the Marietas Islands. The weightlessness, silence, and 360-degree perspective create a profound connection with the bay's hidden ecosystems.
Can't decide? Many guests begin with snorkeling before discovering the magic of diving deeper. Regardless of your choice, Banderas Bay's extraordinary biodiversity means every underwater moment creates lasting memories. Our certified guides handle safety, equipment, and navigation while you focus on pure marine discovery. The Pacific's wonders await—choose your adventure with us today.
