We did this from the north and it's a long long hike. The swim wasn't bad. We dove at slack so currents weren't a problem but it's a full moon beware if you aren't at slack. Tons of crabs. When I swam out to the dock and dropped down I was shocked at the number of crabs there. It reminded me of Indiana Jones and the Temple of Doom when he saw all those snakes on the floor. "Why is the floor moving?"
