The hook-shaped peninsula is a popular summertime destination. Cape Cod National Seashore comprises 43,604 acres of shoreline and upland landscape features, including a 40-mile long stretch of pristine sandy beach, dozens of clear, deep, freshwater kettle ponds, and upland scenes that depict evidence of how people have used the land. Take a boat tour or ride a bike on one of the popular trails. Make time for the Coast Guard Beach, a prime swimming beach. Take the bicycle trail bridge where people can see shorebirds working the tidal flats in the warmer months, according to NPS. The outer beach, or “backside,” of Cape Cod has been the infamous graveyard for more than 3,000 ships since the 1600’s.
