THE DIVES

Two guided dive sites in one afternoon

This outing visits two different dive sites, with each dive led by a certified dive master or instructor — ideal for spotting new life on successive bottom times and for divers seeking a compact, high-value afternoon in the water.

THE OPTIONS

Nitrox and non-diver options

Divers can elect to pursue a Nitrox certification on this trip (pre-scheduled) and non-diving family or friends may join the same boat and snorkel with a snorkel guide, keeping groups together above and below the surface.

THE BASICS

Simple logistics, focused diving

The format is straightforward: board the dive boat, complete briefings, and complete two guided dives in a single afternoon — an efficient way to sample St. Thomas diving without a full-day commitment.

What the day feels like

How the afternoon feels

The trip unfolds like a deliberate short expedition: a boat departure with a concise briefing, two distinct guided dives where the focus is on exploration and safety, and the option for non-divers to stay engaged from the surface. Whether it’s your first time with this operator or your fortieth, the format emphasizes guided, repeatable access to local reefs.
