Start matching an undercling on the jug towards the bottom of the crack that runs through the middle of the boulder. Continue straight up the crack, then slightly to the right to finish.
If you approach the 'whale tail' (rock formation in the center of the 2 beaches, dividing little harbor from shark harbor) from the little harbor side, traverse around until you reach the first large boulder. It is immediately in front of a cave. This would be the end of the route if you are completing the Welcome to Little Harbor traverse (you should).
Since the boulder is low, one could conceivably fall carefully amongst the small rocks surrounding the boulder. Crash pad is extremely useful.
