The Sandwich Boardwalk.

Exit off Route 6 just after the Sagamore Bridge and go about three miles up 6A toward Sandwich. Turn left on Jarves Street and head down to the Sandwich Boardwalk. Devastated  by Hurricane Bob in 1991, it was rebuilt by selling more than 1700 personalized planks. You can see them in the picture. Keep your head up towards the end so you don't walk right into the bay.
