Eden Rock & Devil's Grotto

Twin limestone formations off George Town's South Church Street that rise from a sand floor to within a metre of the surface, riddled with caverns, tunnels and skylight chambers where shafts of sunlight cut through the dark interior. In summer a dense silver curtain of silversides packs the chambers, hunted by resident Atlantic tarpon in lunging attacks that scatter the schools into swirling clouds. Caribbean reef squid hover at the entrances and great barracuda patrol the perimeter, all in clear water that rarely runs more than a gentle drift. Depths of 4 to 15 m make this the most dived shore site on Grand Cayman.
