The Location and Setting
Costa Maya’s Mahahual reef offers an underwater paradise that’s both accessible and teeming with life. Known for over 65 species of stony corals, 350 molluscs, and 500 fish species, the reef is a vibrant, colorful tapestry. It’s also a refuge for several endangered species, including green, hawksbill, and loggerhead turtles, as well as the Caribbean manatee and the elusive Moreleti crocodile.
You’ll start your morning at Mar Adentro Diving, just a short taxi ride from the cruise terminal. From there, a quick 10-minute speedboat whisks you out to the first of the dive sites, which are spread across five different underwater landscapes at depths ranging from 45 to 90 feet. The typical visibility of around 90 feet ensures you’ll have plenty to see without feeling overwhelmed.
The Itinerary and Experience
The tour is structured around two main dives, each lasting approximately 50 minutes, with a 40-minute surface interval spent relaxing at Blue Kay Beach. During your time at the beach, you can enjoy fresh water, coffee, and a fruit snack, making this a pleasant pause in the day’s underwater adventures.
The first dive usually explores the most vibrant reef areas, where you’re likely to encounter turtles, moray eels, nurse sharks, rays, and a swirl of tropical fish like angelfish, butterfly fish, and parrotfish. The second dive continues to showcase different landscapes, giving you a varied perspective on the reef’s diversity.
What makes this experience stand out is the personalized approach. The staff takes care to match dive sites to your experience level and make you comfortable. If you prefer a private dive master, you can pay an extra $30 USD, which might appeal to those wanting more one-on-one guidance or specific interests.
The Underwater Spectacle
We loved the way the staff emphasized marine conservation, pointing out protected and endangered species, which adds depth to the experience beyond just seeing pretty fish. The reef’s five different landscapes mean every dive feels unique, from lush coral gardens to dramatic wall formations.
According to reviews, guides are knowledgeable, and the viewing conditions are generally excellent, with calm seas and clear water. The chance to see sea turtles, barracudas, groupers, and rays swimming in schools is often highlighted as a highlight. One reviewer from Canada called the experience “amazing,” while a Swiss traveler summed it up as “very good experience.”

For $98, your package covers full scuba gear, though notably not a dive computer, which you might want to bring or rent separately if you prefer. The divemaster guides are committed to safety, maintaining a maximum ratio of 1:5, which supports a comfortable, attentive experience.
Transportation costs—like the taxi ride to the dive center—and park entry fees (a modest $3 USD for the Mexican Caribbean Park) are not included, so keep those in mind. The tour operates rain or shine, but safety takes precedence if sea conditions are unsafe.
Practical Tips
- Bring your certification card and any personal gear you prefer.
- Use reef-friendly sunscreen 20 minutes before the boat ride, as regular sunscreen can damage the coral.
- Avoid alcohol before diving to ensure safety.
- The tour is not suitable for children under 10, pregnant women, or anyone with certain medical conditions, including high blood pressure.
Summing Up the Experience
This tour offers excellent value for certified divers who want a relaxed, well-organized day exploring some of the Caribbean’s most beautiful reef systems. The short boat rides, diverse marine life, and friendly staff make for a memorable outing.
While it’s a shared boat experience, the attention to safety and individual needs ensures you won’t feel lost in a crowd. The beach stop adds a nice touch of comfort after your underwater adventures, making it a well-rounded day.
