If you’re considering a marine experience in St. Maarten, the SeaTrek Tour offers a chance to walk along the seafloor in a way that’s accessible to non-swimmers, children, and the faint-hearted alike. This activity stands out because it combines snorkeling with a guided underwater walk—a mix of fun, safety, and stunning sights. It’s a popular choice, with over 42 reviews and a solid 4.0-star rating, which indicates most travelers find it worth the time and expense.
What we particularly like about this experience is how well it balances adventure and comfort. First, it offers a guided underwater walk using a specially designed helmet that allows you to breathe normally—no diving certification or swimming skills required. Second, the friendly guides often receive praise for their attentiveness and patience, especially with nervous guests. The tour is also quite flexible; it combines both snorkeling and underwater walking, giving you a taste of each without the need for deep-sea diving experience.
However, it’s worth noting that weather conditions can impact the tour—since it’s an outdoor activity on the water, cancellations due to weather are possible, sometimes last-minute. Also, the price—roughly $109.65 per person—is on the higher side if you’re comparing other excursions, but many find the value justifies it due to the uniqueness of the underwater walk and the marine life encounters.
This tour is best suited for families, non-swimmers, adventure seekers who want a new experience, and those curious about seeing marine life in a safe, guided setting. If you love marine environments, but are hesitant about diving or snorkeling, this is a fantastic option.

How the Tour Is Structured
The tour begins at Bobby’s Marina in Philipsburg, a convenient and accessible meeting point just a short walk from cruise ports and town. Once there, you’ll board a boat that takes you to a platform in the middle of the water—an ideal spot for both safety and scenic views. Here, the friendly staff welcomes you and explains the itinerary, dividing the group into two: one for snorkeling and one for SeaTrek.
The snorkel session lasts about 30 minutes, giving you a chance to float above the coral and constellations of tropical fish. Though some reviews mention that the displays can look a bit aged and rails may need maintenance, most guests enjoy the clarity of the water and the abundance of fish—”The fish were everywhere, the water was clear and the staff was attentive,” one reviewer noted.
Meanwhile, the other group prepares for the SeaTrek, which involves descending a ladder with 20 steps (about 20 feet) to the seabed. The staff emphasizes the importance of trying on the helmet to ensure a snug fit, as it’s crucial for a leak-free experience. Once at the bottom, you follow a marked path along guided railings, making the walk both comfortable and secure.
The underwater helmets are spacious, allow normal breathing, and ensure you stay dry—making this experience suitable for those who might be uncomfortable with traditional diving gear or water pressure. Many reviews highlight how reassuring and careful the staff are, especially for guests with nerves or limited water confidence.
The Snorkeling and Underwater Walk
After the snorkeling, you’ll switch activities—returning gear and preparing for the underwater walk. The guides do a great job of explaining what to expect, giving you confidence before descending. The underwater path is not overly long but is packed with marine life, including colorful fish, sea urchins, and even stingrays if luck is on your side.
Guests consistently praise the supportive staff—”They answered any concerns and constantly checked on us while underwater,” one reviewer shared. This attention to safety and comfort is key, especially for first-timers or nervous travelers.
Duration and Group Size
The overall activity lasts about 2 hours and 15 minutes, which balances enough time underwater without feeling rushed or overly long. The group size is capped at 24 travelers, ensuring everyone gets attention and support. This small-group setting enhances the personalized experience, especially important if you’re feeling anxious or want more guidance.
What’s Included and What’s Extra
The tour includes snorkel gear, free lockers for your belongings, the boat ride, and one free drink—a simple but thoughtful touch. You can purchase photos taken underwater, and snacks or drinks are available at an additional cost. Transportation to the meeting point isn’t included, so you’ll need to arrange your own transfer or use public transportation nearby.
Price and Value
At about $109.65 per person, this tour isn’t the cheapest, but it offers a unique blend of physical activity and marine sightseeing. Many guests feel the price is justified because it provides a safe, guided, hands-free underwater experience that’s hard to find elsewhere. For those who have limited time in St. Maarten or are eager to tick off a memorable activity, this is a convenient and fun option.
Weather and Cancellation
Since the activity depends heavily on weather conditions, cancellations are possible and can be last-minute. Several reviews reflect frustration over last-minute cancellations, especially for weather reasons, which can be disappointing if you’ve built your plans around it. The policy allows for free cancellations if done 24 hours in advance.
Authentic Guest Experiences
Guest reviews paint a balanced picture: some find the experience absolutely magical—”The staff was very careful with our safety the entire time. It was a new experience for me but they were all reassuring,” one reviewer said. Others, however, have faced issues like poor communication or cancellations—”The operator was a no-show,” or “The tour was significantly delayed,” highlight the importance of verifying bookings and weather.
Potential Challenges
The main drawback seems to be the possibility of last-minute cancellations or delays, which can seriously affect cruise schedules or day plans. Plus, the cost may seem steep relative to other activities, but many find the unique underwater walk worth the premium. It’s also not suitable for guests with certain health issues—back/neck injuries, ear problems, asthma, or claustrophobia—so prior assessment is wise.
Who Should Consider This Tour?

This activity is perfect for families, adventurers, and non-swimmers looking to experience the underwater world without diving gear. It’s especially appealing if you want a safe, guided experience with marine life sightings and don’t mind paying a bit extra for the convenience. If you’re nervous about water or don’t want to get wet, the helmet walk offers a comfortable and exciting alternative to snorkeling or diving.
However, if you’re on a tight schedule or worried about weather cancellations, it’s best to be flexible and prepared for last-minute changes. The tour is ideal for those who want an interactive, memorable experience that captures the essence of the Caribbean sea from a new perspective.
