Under the water
Diving and snorkeling from Union Island
The Grenadines are not only about beaches and sailing. Some of the best memories happen under the surface: reef fish, turtles, coral gardens, clear water, shipwrecks, and quiet snorkel stops close to Union Island.
Scuba
Diving with certified dive shops
Scuba diving should always be planned through a certified dive shop. Union Island has local dive options in Clifton, and certified operators decide the right site, depth and conditions for each diver.

Certified diving around Union Island
Scuba diving in the Grenadines should be done with a certified dive shop. Conditions, currents, depth, visibility and diver level all matter, so the right operator will choose the site and plan the dive safely for the day.
Grenadines Dive is based in Clifton, in the center of Union Island, and is one of the easy local dive contacts to find online. Their published dive information lists Union Island, Mayreau, Tobago Cays and Sail Rock sites, with instruction available through NAUI or PADI professionals.
Dive days can include easy coral sites, drift dives, deeper reef formations, shipwrecks and weather-dependent advanced sites. Examples around the Southern Grenadines include Mayreau Garden, the Puruni Wreck, Horseshoe Reef, Petit Tabac and Sail Rock. The certified dive shop should always decide what fits the guests, the weather and the sea state.
Tobago Cays
Snorkeling in the Tobago Cays
The Tobago Cays are one of the most famous places in the Grenadines for snorkeling. The water can be crystal clear, the colors are intense, and a boat day can combine beaches, reef snorkeling, turtle watching and a classic Grenadines lunch stop.
Two snorkeling experiences stand out. The outer reef gives you coral, fish and open-water reef scenery, while the Baradal turtle area is known for green turtles feeding over seagrass. Turtles can be approachable, but visitors must never touch, chase, crowd or block them. The best photos happen when the animal is relaxed and you keep a respectful distance.
The Tobago Cays are also a beautiful anchorage for sailboats exploring the Grenadines. When lobster is legally in season, a beach barbecue can be part of a full-day trip. Always follow local park rules, your captain’s instructions, and current guidance on wildlife, reefs and seasonal food rules.
Union Island snorkeling
Snorkeling and shipwreck days from Union Island
Not every underwater day needs to be a scuba day. JT Pro Center can help guests think through relaxed snorkeling options around Union Island, depending on the weather, visibility, boat availability and the level of the group.
Ask about snorkeling and shipwreck-style activity days where guests can spend a couple of hours in the water and explore a wreck or shallow underwater site without dive tanks. It is a good option for families, mixed groups, partners who do not dive, and guests who want a lighter underwater experience between kite, wing or island days.
For any shipwreck, reef or turtle stop, the route should stay flexible. Wind direction, swell, current, visibility and guest confidence decide what is realistic. The goal is not to force a fixed itinerary, but to choose the safest and most enjoyable underwater stop for that day.
Stay, learn and explore
Add kitesurfing lessons to your Union Island trip
A diving or snorkeling holiday can also be a good moment to learn kitesurfing. Union Island has warm shallow water, flat-water areas, private instruction options and safety boat support, which makes it easier for beginners to build confidence.
Guests can keep the week flexible: kite lessons when the wind is right, snorkeling or Tobago Cays trips on lighter days, and relaxed island time between sessions. It works especially well for couples, families and mixed groups where not everyone wants the same activity every day.
Mer & Sel
Stay at Mer & Sel Private Villa
For guests who want the trip to feel more complete, Mer & Sel gives you a comfortable Union Island base with sea views, space to relax, and easy access to the kite spot, Clifton, boat trips, snorkeling days and Grenadines excursions.
It is a good fit when you want the underwater activities, the kite school and the island stay to work together instead of booking everything separately. Current availability should always be confirmed by inquiry.
