The Exumas reward travelers who choose the right base. Stay around George Town on Great Exuma for Dive Exuma's local reef, Tug wreck and Angelfish Blue Hole trips, Stocking Island, kayaking and beaches. Stay around Staniel Cay for guided snorkeling at Thunderball Grotto, Big Major Cay, nearby sandbars and northern-cay boat days. These are not adjacent sightseeing neighborhoods: moving between them may require a dedicated charter, flight or multi-leg transfer, with weather and operating schedules decisive. The Exuma Cays Land and Sea Park has strict no-take rules; Moriah Harbour Cay National Park has additional local regulations. March through May is a useful broad planning preference, not a guaranteed flat-sea window. Dedicated freediving training and regular whale-swim programs are not independently verified. Choose between island-based day trips and dedicated Exuma Cays dive liveaboards embarking in Nassau; confirm the actual itinerary, qualifications, tides, closures and emergency arrangements before travel.
