The Itinerary and Experience Breakdown
When you book this tour, you’re signing up for a two-hour jaunt that combines a scenic boat ride with an underwater exploration. The departure usually happens in the morning or afternoon, giving you flexibility depending on your plans.
The adventure begins with a boat ride, which is not just a way to get to the snorkel site but also an opportunity to appreciate the coastline and learn about the local marine ecosystem from your guides. According to reviews, the guides are especially good at sharing their knowledge, making the ride both enjoyable and educational. One reviewer mentioned, “We loved the way the guides explained the importance of conservation during the boat ride, which added depth to the whole experience.”
Once at the sanctuary, it’s all about snorkeling. You’ll be given your gear—mask, fins, wetsuit top, and water—and guided through how to use everything safely. The coral reefs are teeming with life, according to those who’ve gone: “The variety of fish and turtles was incredible, and the guides pointed out fascinating behaviors and habitats.” The underwater world here is vibrant and lively, and many mention how clear the water is, making it easier to spot marine creatures.
Marine Life and Underwater Highlights
Expect to see colorful fish darting between coral beds, sea turtles gracefully gliding by, and rays lazily resting on the seabed. Some participants have also caught glimpses of elusive eels and playful octopi, which adds a layer of excitement. The guides are experienced at pointing out these creatures, making the snorkeling feel like a mini wildlife safari in your own gear.
The Educational Component
A big plus for many reviews is the educational aspect. The guides don’t just lead you around; they teach you about the local ecosystems, explaining how coral reefs function, the significance of conservation efforts, and how human activity impacts these fragile environments. If you’re interested in marine conservation or simply want to understand what makes this sanctuary so special, this tour offers more than just pretty sights.

All necessary snorkel gear is included, which means no need to rent or buy equipment beforehand. The wetsuit tops help protect against the sun and keep you comfortable in the water. Since water is also provided, you stay hydrated during your short but immersive trip.
If you’re worried about comfort or safety, note that the tour is limited to small groups, which generally means more attention from guides and a relaxed atmosphere. Keep in mind, though, that non-swimmers or those with seasickness might find it less suitable, as the experience involves being in open water.
Duration, Timing, and Logistics
The two-hour duration feels just right—long enough to get a good look at marine life but not so long that it becomes tiring. Make sure to arrive 30 minutes early for check-in, as late arrivals can’t be accommodated. You’ll need to bring your own swimwear, towel, camera, and sunscreen—which are standard for water activities and won’t be provided.
Cost and Value
At $471 for up to four people, the price might seem steep at first glance. But consider what you’re getting: guided snorkeling with all gear included, a scenic boat ride, educational insights, and the chance to see some incredible marine life in a protected environment. For those who love learning and exploring underwater ecosystems, the cost can be justified, especially compared to individual gear rentals or unsupervised snorkeling trips.
Who Should Consider This Tour?

This adventure is ideal for adventure-seekers, wildlife enthusiasts, or anyone interested in marine ecosystems. It’s particularly suited to those who appreciate guided experiences and value educational components. The small group setting makes it a good choice for travelers who prefer a more personal touch rather than large, impersonal tours.
If you’re traveling with children or anyone who isn’t comfortable in open water, keep in mind the restrictions—it’s not suitable for non-swimmers or those with certain health issues. Also, if seasickness is a concern for you, it’s worth considering whether a calmer boat ride might be necessary.
