Bloody Bay Wall, on the north shore of Little Cayman, is consistently ranked among the world's top wall dives. The reef begins at only six metres below the surface and ends — visually at least — in deep blue at the bottom of your vision. The face of the wall is covered in barrel sponges, sea fans, black coral and crinoids; eagle rays, reef sharks, hawksbill turtles, and the occasional silky shark drift past in the open water beyond.
The site sits within the Bloody Bay Marine Park, where mooring and fishing are forbidden, and the dive sites along the wall — Donna's Delight, Three Fathom Wall, Marilyn's Cut and others — are accessed by short boat trips from the island's dive lodges. Visibility is reliably over 30 metres and water temperatures stay between 26 and 29 degrees year-round. Most divers do two tank dives a day; the appetite for the wall does not fade.
