Caesar's Rocks

The five towers rise from 30 m to about 5 m below the surface, so the dive is worked in the vertical: down the flank of one pinnacle, along its base, then up and across to the next as gas allows. Soft corals cover the walls and enormous sea fans filter-feed off the sides, the same fans that give shelter to lionfish. When the current is running the corals are at their most open, feeding on what sweeps past.

The passages are the reason divers come back. One pinnacle carries a three-way swim-through with walls shrouded in golden soft corals and fans, and another has a Y-shaped passage straight through it, with light pouring in from both ends and silhouetting the corals inside. A coral-lined tunnel runs along the site at around 15 m. On the rock itself, look for blue ribbon eels, nudibranchs, longnose hawkfish, trumpetfish and blennies, with octopus in the cracks, reef sharks working the rock and schooling tuna and the occasional turtle passing the towers.
