The Cape Cod National Seashore (CCNS), created on August 7, 1961 by President John F. Kennedy,   encompasses 43,607 acres (68.1 sq mi; 176.5 km2)  on Cape Cod, in Massachusetts. It includes ponds, woods and beachfront of the Atlantic coastal pine barrens ecoregion. The CCNS includes nearly 40 miles (64 km) of seashore along the Atlantic-facing eastern shore of Cape Cod, in the towns of Provincetown, Truro, Wellfleet, Eastham, Orleans and Chatham. It is administered by the National Park Service.
Notable sites encompassed by the CCNS include Marconi Station (site of the first two-way transatlantic radio transmission), the Highlands Center for the Arts (formerly the North Truro Air Force Station), the Dune Shacks of Peaked Hill Bars Historic District (a 1,950-acre historic district containing dune shacks and the dune environment), and the glacial erratic known as Doane Rock.
There are several paved bike trails: 
- Nauset Bike Trail - Eastham
- Head of the Meadow Trail - Truro
- Province Lands Trails - Provincetown
There are several excellent beaches along the coastline with public facilities available seasonally. These include Race Point Beach in Provincetown and Coast Guard Beach in Eastham.  Both of these have made "top beaches in the US" lists over the years.  
In 2010, the North of Highland Campground was protected with a conservation easement. The Trust for Public Land, the Association to Preserve Cape Cod, the Truro Conservation Trust, and other groups led a grassroots campaign to support the funding for the purchase price of the conservation easement from the federal Land and Water Conservation Fund (LWCF), secured by U.S. Senator John Kerry, U.S. Representative Bill Delahunt, and former Senator Ted Kennedy.  
The Biddle Property, home of the late Francis Biddle, who was the U.S. attorney general during WW II and served as the primary American judge during the post-war Nuremberg trials, was added to the Cape Cod National Seashore in 2011. Using funding from the Land and Water Conservation Fund, the Trust for Public Land purchased the property and conveyed it to the National Park Service.
