Salt Island earns its Wreck Alley name through the RMS Rhone, a historic shipwreck that forms the centrepiece of diving here and functions as a thriving artificial reef. Beyond the Rhone, the area offers considerable variety: shallow reef dives at Cistern Point and Painted Walls suit beginners, while drift diving at Brewers Bay Pinnacles and the cave system at Grand Central Station challenge more experienced divers. Nurse Shark, Spotted Moray, Green Sea Turtle and both French and Queen Angelfish are consistently observed across the sites.
