An Honest Look at the Under the Sea Tour
When we picture Cozumel, many of us think about its crystal-clear waters and lively reefs, renowned as one of the Caribbean’s top snorkeling spots. This tour capitalizes on that reputation, but it takes a different approach: you’re not just snorkeling on your own; you’re traveling on a high-tech, transparent boat that lets you see the underwater world from above. It’s a playful twist that makes the experience stand out compared to traditional boat rides or snorkeling excursions.
The boat itself is quite the conversation piece. It’s the world’s first of its kind—entirely transparent—so from the moment you set out, you’re treated to panoramic views of Cozumel’s vibrant coral reefs and abundant marine life. Expect to see schools of multicolored fish, graceful rays, and even turtles gliding beneath you, all under the shimmering Caribbean sun. The ride is smooth, and the vessel’s design means your view isn’t blocked by opaque sides or a crowded deck. We loved the way the boat’s transparency amplified the sense of being part of the underwater environment.
The itinerary is straightforward: you hop on the boat in Cozumel’s main area, cruise south along the coast, and enjoy the scenery from the water. The highlight of the trip is the stop at the artificial “Lego” reefs—these structures are designed to be attractive to marine life and are perfect for snorkeling. The guides are experienced and friendly, offering tips and assistance whether it’s your first time snorkeling or you’re more seasoned. They’ll help you navigate the reefs, which are teeming with colorful fish and other aquatic creatures. Many reviews mention the guides’ professionalism and patience, which helps put beginners at ease.
Timing-wise, the duration is about 1 hour 30 minutes, making it a perfect short activity for those with limited time during a cruise stop. It’s a well-paced experience that leaves plenty of time to explore other parts of the island or relax on your own. The tour ends back at the meeting point, leaving no room for the common worry of being late or rushing back to the ship.

What’s Included and What You Should Expect to Pay Extra For

The cost of $44.10 per person includes use of snorkeling equipment, one bottled water, one soda, and two beers—pretty decent for an activity that combines a scenic boat ride and snorkeling. The inclusion of drinks adds to the laid-back vibe, and the guides often create a friendly atmosphere, encouraging everyone to relax and enjoy the moment.
However, there are some expenses not included. You’ll need to budget for a $5 dock tax per person, which is paid locally and is fairly standard in many port activities. Transportation to the meeting point isn’t included, so you’ll want to organize that yourself or plan to walk if your cruise dock is nearby. Also, photography is extra—so if capturing your underwater views is important, consider bringing a waterproof camera or phone.
The small group size (maximum 12 travelers) enhances the experience, allowing guides to give more personal attention. Still, this means it’s a good idea to reserve ahead, especially during peak cruise season when spots fill up fast.
The Experience from a Traveler’s Perspective

Based on what we’ve read and the available reviews, the views from the transparent boat truly seem to impress. Several travelers have praised the clarity of the water and the ease of soaking in the sights without the need to snorkel if they don’t want to. It’s perfect for those who prefer a relaxed, scenic experience rather than getting in the water immediately.
The snorkel stop at the artificial reefs is frequently highlighted as a highlight, with many noting the vibrant marine life and the fun of swimming among the structures. Some reviewers even mention the guides’ helpfulness, saying, “They accompany you step by step, even if it’s your first time in the activity,” which can be reassuring if you’re new to snorkeling.
One potential downside is the weather dependency—since the boat is entirely open, rough seas or rain could affect the experience or lead to cancellations. While the tour is flexible regarding cancellations (free if done 24 hours in advance), you might find the weather can influence your enjoyment.
Who Should Consider This Tour?

This experience is best suited for cruise travelers wanting a quick, visually stunning peek at Cozumel’s marine life without committing to a longer or more physically demanding trip. It’s good for those with moderate physical fitness since snorkeling is involved but not overly strenuous, and the overall pace is relaxed. Families with older children who enjoy boats and water scenery could find it a fun, easy outing.
