The National Park System incorporates 84 coastal park units with shorelines and submerged acreage, including national parks, seashores, lakeshores, recreation areas, monuments, preserves, historic sites, and memorials. These areas encompass over 11,000 miles of Great Lake and ocean shoreline and contain important American natural and cultural features. More parks are near the coast and are affected by coastal processes such as storms.

Coastal park features include the black sand beaches of Hawaii Volcanoes National Park, cultural resources of Bering Land Bridge National Preserve, immense sand dunes in Sleeping Bear Dunes National Lakeshore, and the largest subtropical wilderness in Everglades National Park.

Increasing pressures and environmental threats such as coastal population growth, pollution, and sea level rise are impacting coastal areas. The National Park Service works to protect and understand the coastal resources in its care such that they are unimpaired for future generations.
