Planning a trip to Puerto Vallarta and wondering if a scuba adventure here is worth it? We haven’t personally done this tour, but based on its details and reviews, it looks like a solid choice for anyone eager to explore the region’s underwater beauty.
What we really like about this experience is the focus on guided exploration by experienced PADI Divemasters, which helps ensure safety and a richer experience. Plus, the stunning visibility and diverse marine life—rays, sea turtles, colorful nudibranchs—are major draws. On the flip side, one thing to keep in mind is that it’s about six hours long, so if you’re not used to full-day outings or have limited stamina, it might feel a bit lengthy.
This tour is best suited for travelers who are comfortable with scuba diving or eager to try it, and who appreciate well-organized trips with expert supervision. It’s not ideal for children under 10, but for adults looking for a memorable underwater adventure, it’s quite promising.

The Marine Environment and Underwater Highlights
One of the best parts? The visibility. Many reviews highlight how clear the water is, making it easier to appreciate the stunning formations and vibrant marine life. You can expect to see colorful nudibranchs—those tiny, beautiful sea slugs—along with larger creatures like turtles and rays.
The rock formations themselves are a major draw. They create tunnels and caves perfect for exploring. It’s a chance to see marine life in a natural habitat that’s full of hiding spots and nurseries. The experience of swimming through arches and caves adds an extra element of excitement.
The Guides and Group Size
Having a PADI-certified Divemaster guiding you is a big plus. Their expertise not only keeps you safe but also enriches your understanding of what you’re seeing. The group size is limited—max 5 guests per guide—which means you’ll get plenty of personalized attention, and your questions are likely to be answered.
Equipment and Comfort
All the necessary gear—mask, fins, wetsuit, regulator, BCD—is included, so you don’t need to worry about bringing your own unless you prefer your own equipment. The wetsuits are suitable for the water temperatures, and the gear is generally well-maintained, according to reviews.

An Honest Look at the Downside

While many reviewers praise the experience for its stunning views and knowledgeable guides, some mention that the length of the tour can be a bit tiring if you’re not used to a full-day activity. Also, the cost of $250 might seem high for some, but considering it includes two tanks, gear, lunch, and transport, many find it reasonable.
Another thing to consider is age restrictions—children under 10 aren’t suited for this trip, so it’s more for teenagers and adults. If you’re not comfortable with scuba or snorkeling, this probably isn’t the right experience, as it involves diving.

However, if you’re not comfortable with diving or prefer a shorter activity, you might want to explore other options, like snorkeling or land-based excursions.
