Though its really chilly and windy in the spring, we take the ferry over to ride our bikes or just go on foot, and meet up with friends over there who have automobiles.
Its a fun place, but not great for swimming. We go over on the little boats once in a while, but you have to really watch the weather, or you will get winded out and have one heck of a time getting home to Woods Hole.
Look at us on Google Earth, its neat.
Forgot to mention, about an hour later on after we had lunch, there were a whole bunch of Naked adults on that beach down below the cliffs. It was too cold to swim, but they were running all around there.
