If you’re considering a scuba trip in St. Thomas, the Two Tank Dive offered by Aqua Action Dive Center is a well-reviewed option that promises a memorable underwater experience. With a perfect 5-star rating from over 130 reviews, it’s clear this tour has struck a chord with many travelers. Designed for certified divers, this 3.5-hour boat excursion offers a chance to explore vibrant reefs, shipwrecks, and encounter fascinating marine life—all in a relaxed, friendly atmosphere.
What we love about this experience are the small group size—a maximum of 12 divers—which creates a more personal, attentive environment, and the diverse dive sites, including wrecks and reef systems teeming with turtles, rays, and fish. A second highlight is the professionalism of the crew combined with genuine warmth, making the trip both safe and enjoyable.
A possible consideration is the booking process, which requires some planning—most guests book about 39 days in advance—and the minimum guest number policy, meaning trips might be canceled if not enough divers sign up. This isn’t unusual but is worth keeping in mind if your schedule is tight.
This tour suits certified divers looking for a straightforward, well-organized, and friendly dive outing. If you’re eager to explore the underwater world of the US Virgin Islands with knowledgeable guides and a small group, this trip could be just the ticket.
