A wild Mid-Atlantic barrier island defined by shifting sands, salt marshes, and free-roaming horses.
Assateague Island National Seashore
Assateague Island National Seashore is a protected barrier island along the Atlantic coast of the Delmarva Peninsula, spanning southern Maryland and northern Virginia. It preserves one of the largest and least-developed barrier island ecosystems in the Middle Atlantic states, a dynamic landscape shaped by storms, tides, and longshore sand movement. The seashore protects miles of ocean beach, quiet bay shoreline, and extensive salt marsh that support a rich community of shorebirds, seabirds, wading birds, and migratory species.
The park is best known for its wild horses, often called Chincoteague ponies or Assateague horses, which roam freely across the dunes and marshes. Two separate herds live at the northern and southern ends of the island under different management arrangements, making the horses both an ecological curiosity and a cultural icon of the region. The combination of natural coastal processes, abundant wildlife, and accessible recreation makes Assateague Island a representative example of a working Atlantic barrier island under federal protection.
As a National Seashore unit of the U.S. National Park Service, the park balances preservation of fragile coastal resources with public use. Visitors come for beachgoing, surf fishing, wildlife observation, and a sense of open, undeveloped Atlantic shoreline that has largely disappeared elsewhere along the heavily populated Eastern Seaboard.
