Killer Pillar on Grand Cayman might not be the flashiest name on the map, but we love it for its quiet charm and that truly unique pillar coral. It’s one of the few spots in the Caymans where you can reliably find it growing, a real treat to see its upright, finger-like formations reaching for the surface. We usually drop in here for a relaxed, shallow dive, peaking at about 17 metres. The pillar coral itself sits right on the edge of a mini-wall, a short swim northeast from the mooring. As you drift along, keep an eye out for the smaller inhabitants too; we've often spotted shy Speckled Worm Eels peeking from the sand and the vibrant flash of Yellowtail and Midnight Parrotfish cruising by. It’s a great site for photographers who appreciate the subtle beauty of a healthy reef and for anyone who enjoys a peaceful dive without strong currents. The average 25-metre visibility makes it easy to take in the details, from tiny Goldspot Gobies to the occasional Black Moray tucked away.
