I've dove here between 40 and 50 times. This is the South cove that everyone knows. The hike down/up is tough unless the path has recently been improved. There are rock falls in the area that rarely allow things to stay unchanged very long. Be vary wary entering the water. The beach can be rocky and slippery as well as steep. Wave can be unpredictable and one should take a fair amount of time to observe the wave sets before entry. I've made the three hour drive a number of times and not got in the water due to hazardous surf. Vis is generally poor though I've seen upwards of 40 ft on occasion. Take a flashlight. I've take out many fairly large pieces and one of 750 lbs before the new regs took effect. The S cove is generally shallow to about 25 ft. A few large boulders and areas of sand an pebbles. Best hunting along the shallows to the N and the rocky bed area S/E of the cave rock. The N cove is very good diving but the trek down is much more arduous. I love Jade Cove, N and S. Have fun but take a lot of care and be safe. Rouge waves are not uncommon.
