The Marconi Wireless Station Site commemorates the location of the first transatlantic wireless transmission between the US and Europe in 1903.
The park contains 'kettle ponds,' which are glacial depressions that filled with water when ice blocks melted at the end of the last ice age.
Highland Light, also known as Cape Cod Light, is the oldest and tallest lighthouse on Cape Cod, originally established in 1797.
The park's dunes are part of a barrier beach system that provides critical protection against storm surges for the mainland.
The Provincelands area, located at the northern tip of the Cape, features a unique landscape of sand dunes that do not support standard forest growth.
The seashore supports over 350 species of birds throughout the year, making it a major stopover on the Atlantic Flyway.
Seal populations in the area have rebounded significantly since the 1972 Marine Mammal Protection Act, which has also influenced local shark migration patterns.
Cape Cod National Seashore protects 43,607 acres of coastal landscape along the Outer Cape, including 40 miles of Atlantic-facing shoreline. The park encompasses diverse ecosystems, ranging from shifting sand dunes and salt marshes to pitch pine and oak forests. It features six primary swimming beaches: Coast Guard, Nauset Light, Marconi, Head of the Meadow, Race Point, and Herring Cove. The Salt Pond Visitor Center serves as a central hub, offering exhibits on the cultural and natural history of the Cape. Visitors can explore 11 self-guided hiking trails that traverse various terrains, such as the Atlantic White Cedar Swamp. The area is home to several historic lighthouses, including the relocated Nauset Light and Highland Light. Established in 1961 by President John F. Kennedy, the park was the first national seashore in the United States. Its geography is continuously reshaped by wave action and longshore drift, which constantly alter the coastline. The seashore hosts significant populations of nesting shorebirds, including the federally threatened piping plover, which may lead to temporary beach closures during nesting season.

Download offline maps before arrival, as cellular service is highly inconsistent across the dunes and remote stretches of the park.
Pack layers for coastal breezes and significant temperature fluctuations between sunny beaches and shaded wooded trails.
Visit the Salt Pond Visitor Center early in your trip to get current alerts on seal sightings and potential beach closures due to shark activity.
Do not attempt to walk through the dunes in non-designated areas, as the sand is highly unstable and the ecosystem is fragile.
Beaches offer limited lifeguard services primarily from late June through early September; visitor centers operate on reduced schedules during the winter months.
Stay on marked trails to protect sensitive dune vegetation; pets are restricted on certain beaches during nesting season.
