Book a flight-inclusive holiday of at least four nights before 30 June at one of three participating resorts and you qualify for a free return flight from Nassau. Seven nights or more earns two free tickets.

The three resorts include Small Hope Bay Lodge on Andros, the largest Bahamian island with 140 miles of barrier reef. This all-inclusive family-run resort of 21 beach cottages with dive centre offers a “low-impact” lifestyle.

Stella Maris Resort on quiet Long Island is an hour’s flight south of Nassau and provides ocean-view rooms and villas and daily boat-dives on both the Caribbean and more rugged and unexplored Atlantic coasts.

Riding Rock Resort in San Salvador has been hosting divers since the 1960s and most of its 50-plus dive sites are on the lee side of the island with caverns, swim-throughs and reefs “teeming with marine life”, including scalloped hammerhead sharks. Vis averaging 40m is promised!
