The dive
The northern drop-off is the most striking face of the pinnacle, its walls blanketed in soft corals of many colours, with a school of yellowfin damselfish circling the rock. Grouper and red sea bream move along the rock, schools of smaller fish hang beside it, and rare macro creatures live on the walls down to the sand at 30 m.
