Pinnacles: south-coast pinnacle dive with big bommies
Pinnacles is a south-coast drop-off dive built around two large coral bommies on a sloping reef. The pinnacles create a relaxed but visually striking profile, with a collapsed structure, a steep reef edge and regular predator movement in the blue. It suits confident divers who like clear structure and a steady look around the bommies.
