RikoRiko Cave

In the Maori language, RikoRiko means 'Dancing Light'... very poetic! In the winter when the sun's low on the horizon, the light bounces on the surface and shimmers on the ceiling of the cave, creating the magical RikoRiko effect. It is the world's largest sea cave by overall volume, no less!

The visibility inside the cave is usually much better than it is outside of it, though there's less light reaching far back; you can expect over 20m visibility! The atmosphere is unique, very airy with prominent peaks... There are lots of nudibranchs on the rocks, a few crayfish and carpet sharks underneath them. A spermwhale ended up rotting in the cave a few years back; before the tide changed and took the mighty corpse away, the jaw bones and a few vertebras were left behind, for the divers to enjoy!  The shallowest part of the cave, at the very back, is about 6m deep, and the wide entrance reads just below 30m on the depth finder. The walls are covered in rich encrusting life and, once outside, the kelp and the cracks in the walls hide such a wealth of marine life that you'd wish your tank last forever!
