Popponesset Peninsula

Popponesset Peninsula is a spit of land in Cape Cod, Massachusetts which extends from the southwestern shore of Popponesset Bay and separates it from Nantucket Sound.

The peninsula is now significantly shorter than seen in the Barnstable County survey of 1880. Portions of the shore have been stabilized with riprap to deter further erosion. Most of this work was done immediately after Hurricane Bob which in 1992 had opened an inlet through the beach. Much of the peninsula is occupied by Popponesset Beach and the remainder is largely residential. The peninsula is home to conservation projects that prevent disturbance of the piping plover - an endangered species of bird. At one point there was also a small convenience store on the beach whose remains can still be seen on the beach in the form of four large pilings driven into the sand.
