Recommended Anchor Alarm Radius

60m when on marine park mooring ball inside the Horseshoe Reef. The mooring buoys are well-maintained and the reef provides exceptional shelter. DO NOT ANCHOR — mooring balls are mandatory. The 60m radius allows for mooring ball swing in strong trades.
About This Anchorage
The Tobago Cays is the crown jewel of the Grenadines — five small, uninhabited coral islands (Petit Tabac, Baradal, Jamesby, Petit Rameau, and Petit Bateau) enclosed within the crescent of the Horseshoe Reef, creating what is arguably the most spectacular anchorage in the Caribbean. The reef provides extraordinary all-round shelter — even in strong NE trades, the mooring field inside the reef sits in flat, crystal-clear water over brilliant white sand. The marine park is a RAMSAR wetland and national protected area — hawksbill turtles nest on the beaches, eagle rays cruise the sandy flats, and the coral gardens are among the healthiest in the Lesser Antilles. MOORING BALLS ARE MANDATORY inside the reef — no anchoring permitted. The marine park warden (usually in an orange patrol boat) collects the fee (XCD $30/night, approximately USD $11) and will also advise on the best available mooring zones. Snorkelling on the Horseshoe Reef itself is extraordinary — swimming alongside sea turtles feeding on the reef is a near-daily experience here.

Hazards
- !Horseshoe Reef approach — careful navigation required; approach from the south or west through established passages; do not attempt the northeast passage without local knowledge
- !Mooring ball crowding in peak season (Jan–Mar) — arrive by 14:00 to secure a mooring; late arrivals may find no balls available and must anchor outside the reef

- !Boat vendors — active throughout the day; friendly negotiation for lobster and bread is expected
Skipper's Tips
- →Tobago Cays is the single most spectacular sailing destination in the Lesser Antilles — it fully justifies all the Grenadines sailing itinerary planning
- →Snorkel on the Horseshoe Reef at dawn before the day charter boats arrive — swim alongside hawksbill turtles in near-solitude
- →The boat vendors' fresh lobster grilled on a beach barbecue on one of the Cays is a Grenadines highlight — negotiate a price and they'll cook it on the beach
- →Arrive by 13:00 in peak season — mooring balls are first-come-first-served and fill quickly; late arrivals anchor outside at Saline Bay, Mayreau
- →The park warden is friendly and informative — ask about turtle nesting activity and where the best snorkelling is on the current tide
