If you are a resident of Aquinnah, or are renting a house or staying at one of the two inns in town you can go to the town beaches on the South Shore, Philbin and Zack’s Cliffs.
The Beach Expert Says:
Zack’s is like the last frontier. Hard to get into, you pretty much have to know someone. It’s very wild and remote feeling, far from civilization with lots of rock. It can make for a nice day with the right group.
