Snorkeling the reef

The shallow, protected water facing Hillsborough Bay is warm, flat and current-free-ideal for wading, swimming laps along the shoreline and easy snorkeling even for beginners. For the best marine life, work the reef off the ends of the cay, where coral heads and drop-offs shelter schools of reef fish, and where visitors report sighting rays, nurse sharks, sea turtles, pufferfish, octopus and darting silversides.↗↗↗

Carriacou's dive shops also run scuba excursions around the island, and the wider marine park is a bird-feeding ground-brown pelicans frequently plunge into the shallows. Watch the conditions, though: the outer and windward edges can run choppy with stronger currents and hidden sea urchins, so keep to the sandy, sheltered side and wear fins.↗↗↗

A protected marine park-rules to respect

Sandy Island sits inside the Sandy Island Oyster Bed Marine Protected Area, one of Grenada's most biologically diverse reserves, encompassing coral reefs, oyster beds, mangrove fringe, seagrass beds and small islets that together shelter hawksbill and green sea turtles. Because of that status, a few firm rules apply: taking coral, shells or sand is prohibited, turtles and their eggs are protected, and-critically for boaters-anchoring on the fragile reef is forbidden. Use the park's mooring balls instead; rangers patrol and enforce the rules, and there is a small per-person snorkeling and mooring fee.↗↗↗

The shallow reefs here have been battered by coral disease, storms and past heavy use, so the local conservation case for treating the cay gently is real. Take every wrapper and bottle back to Carriacou-there are no bins or facilities on the island-and you'll help keep it the picture-perfect place people come for.↗↗↗

Getting to the cay

From Carriacou the crossing is short and easy. Local fishermen and open-air water taxis run from the Hillsborough pier or from Paradise Beach, dropping you on the sand and returning at an agreed time; the hop takes only about ten to fifteen minutes. A popular option is the boat shuttle from the Paradise Beach Club, which pairs nicely with a meal there. If you're feeling energetic, kayaks can be rented at Paradise Beach and the paddle across is straightforward in light winds-mind the current and passing boats.↗↗↗

For sailors, Sandy Island is a signature stop on Grenada and Grenadines charters, and many choose to tie up to a mooring and spend the night in the sheltered lee, protected from the Atlantic swell. Reach Carriacou itself from mainland Grenada by the Osprey ferry from St. George's (roughly an hour and forty-five minutes, daily except Sunday) or by the short SVG Air flight.↗↗↗

What to bring and how long to stay

There is nothing on the island-no toilets, no running water, no restaurant and no rentals-so this is a true bring-and-remove-everything affair. Pack your own snorkel mask, fins and gear, plenty of drinking water, snacks or a picnic, cash in Eastern Caribbean or US dollars for the boat and marine-park fees, and serious sun protection: reef-safe sunscreen, a hat, a UV shirt and ideally your own shade, since the palms offer little relief and the midday sun is fierce.↗↗↗

Two to three hours is plenty for a swim, a snorkel and a lazy stretch on the sand; arrive before mid-morning to beat the heat and the day-tripper crowds, and save an afternoon for the restaurants and bars back on Paradise Beach. The dry season, roughly January to May, brings the steadiest weather and calmest water for the crossing.↗↗↗

A shifting, weather-worn sandbar

Worth knowing before you go: Sandy Island is a living, low-lying sandbar that erodes and rebuilds with every storm, and Hurricane Beryl, which struck on 1 July 2024, stripped away much of the cay's western vegetation and area and damaged nearby reef and Carriacou businesses. Recent visitors report that the eastern end still snorkels beautifully and that the east half retains some shade, but the island looks leaner than in older photos and the local tourism economy is still recovering. Set your expectations accordingly and check current ferry, boat and accommodation conditions on Carriacou before booking.↗↗↗
