Sharks cove has some of the clearest vis on island. I have always seen no less than 4 turtles every time I've been. To add an alternate entry point for this dive, you can enter through the elevator instead of walking down the trail. If you check out the photo for the dive, on the right in the rocks there is a hole. If you drop into the hole you can swim through a short cavern straight out into the reef and walls. It just makes the dive a little more enjoyable. Just time your entry with the waves and you will be alright.
