From the top of the sheer cliff that shelter the bay you can look straight through the clear water and see mingling sharks (yellow reef sharks) at the bottom. Sea turtles do also occasional cruise by and can be seen in the surf. You can not access the black sand beach at Sharks Bay, but you can go around the northern tip, climb down a ladder, and walk along the rather deserted beach on the other side. A beautiful and tranquil walk that can be extended all the way to Port Resolution (needs a bit of inland walking) where the gorgeous White Sand Beach lies.
