Things move a little slower here in Harwich, and that's part of the appeal. It has good beaches and restaurants and one of the Cape's most photographed spots – yacht-packed Wychmere Harbor. Most of what you'll need is along MA 28, which runs through the south side of town.
Harwich has fine beaches, although many of them restrict parking to residents. But fret not: to get to Sea St Beach, one of the prettiest, park your car for free at the municipal lot behind the tourist office and then walk five minutes to the end of Sea St, which terminates at glistening Sea St Beach.
