Carriacou (Tyrrel Bay)
Small-island reef diving, easy cay snorkels, and a culture-rich base on Grenada's quiet Grenadine outpost
Updated Mar 25, 2026 • 27 sources
Safety And Conservation
Carriacou is easy to love because the water is warm and the island feels relaxed, but it is still a remote diving destination with small-island medical and transport realities. Dive conservatively, carry visible surface signaling, and treat marine-park etiquette as part of the trip, not as a footnote.
Top Risks
- Primary risk: Storm-season transport risk
- Secondary risk: Current-heavy south and offshore sites
- Emergency contact: National emergency services (911)

Dive safety
Choose sites that match your actual skill, not just your ambition. Easy reef dives exist, but Carriacou also has real current sites and deeper wrecks that can tempt people beyond their normal comfort zone. Carry a computer and delayed SMB, stay with the guide on drift profiles, and do not assume a quick chamber ride is available from the dock. Warm water can make divers casual about hydration and sun load, so manage both before and after dives.
Princess Royal Hospital serves Carriacou and Petit Martinique, which is exactly why you should carry dive and evacuation insurance. Serious dive injuries may require stabilization on Carriacou and onward transfer to Grenada's mainland medical network. Government emergency services list Princess Royal at +1 (473) 443-7400, with ambulance access via 774. In St. George's, St. Augustine's Medical Services advertises emergency care and hyperbaric medicine, but DAN notes that chamber availability can change, so involve EMS and your insurer early.
Snorkel and freedive safety
Storm-season transport risk
June to November is the wetter, more weather-sensitive part of the year. Flights are small, ferries can shift, and post-storm recovery logistics can linger longer here than on a big island.
Current-heavy south and offshore sites
Sites such as Sisters Rocks and Black Rocks are not casual drops. Treat guide briefings seriously, carry a DSMB, and do not stretch your certification just because the water is warm.
Anchorage and small-boat traffic
Tyrrel Bay is a working yachting area as well as a leisure base. Surface swimmers and freedivers should use visible floats and avoid drifting far from boat support.
Wildlife and protected areas
The Sandy Island Oyster Bed Marine Protected Area exists to protect reef systems, mangroves, seagrass beds, and small islands on Carriacou's south-west side. Public protected-area material lists spear fishing as prohibited and bans several other extractive gear types as well. For visitors, the practical rule set is simple: do not touch coral, do not stand in seagrass or on mangrove roots, do not harass turtles, and treat nesting beaches such as Petit Carenage with real care. Operators and local groups also support reef monitoring, coral work, and turtle conservation.
Do Not Do This
Avoid entering when storm-season transport risk. Confirm local briefings before committing.
