McCurly’s Wall - Grand Cayman
Pinnacle 1 sits a quick boat ride from Sanctum Una Una, a solid spot for getting oriented with the local diving. It's a triangular pinnacle, starting shallow at 5 meters and dropping to a manageable 22 meters, making it quite popular with open water students. We’ve found the average visibility hovers around 17 meters, good enough to spot schools of black snapper and the occasional eagle ray cruising by. Look closely for Blotchfin scorpionfish blending into the coral. Night dives here are a different experience altogether, with banded coral shrimp out and the subtle glow of bioluminescence.
