Crystal Rock is a few kilometres from Castle Rock. The top is about 3–5 m at low tide and can submerge at high tide. The water is clear. Current can come from two directions as you round the rock.
A dive is about 10–30 m. Whitetip sharks often rest in the current shadow. Trevally and tuna are on the side that faces the current. In the cracks there are nudibranchs, frogfish, moray eels, and scorpionfish. The hard and soft coral is dense.
