Cape Cod National Seashore

Cape Cod National Seashore encompasses approximately 43,500 acres along the outer arm of Cape Cod in Massachusetts, established by Congress in 1961 to protect the peninsula's Atlantic coastline from residential and commercial development. The protected area stretches roughly 40 miles from Chatham in the south to Provincetown at the northern tip, encompassing ocean-facing Atlantic beaches, freshwater kettle ponds formed by retreating glaciers at the end of the last ice age, maritime heathlands, pitch pine and scrub oak forests, and four historic lighthouses. The most celebrated beaches include Race Point Beach and Herring Cove Beach near Provincetown, both accessible by vehicle and backed by expansive dune systems; Nauset Light Beach and Coast Guard Beach in Eastham, which appear regularly on national best-beach rankings for the quality of their Atlantic surf; and Marconi Beach in Wellfleet, adjacent to the hilltop site where Guglielmo Marconi successfully transmitted the first transatlantic wireless message on January 19, 1903. The Province Lands Visitor Center near Provincetown offers interpretive exhibits on the ecology and human history of the outer Cape and provides the starting point for a paved 7-mile bicycle trail network winding through the Province Lands dunes. The Salt Pond Visitor Center in Eastham presents complementary natural history exhibits and hosts ranger-led programs throughout the summer season. Swimming is excellent on the Atlantic-facing beaches from late June through early September, with lifeguards on duty at the main beaches during peak hours. The seashore's freshwater kettle ponds — including Gull Pond, Newcomb Hollow, and Turtle Pond — offer calmer swimming conditions without ocean surf or rip currents, making them particularly suitable for children and less confident swimmers.
