This historic park is the quarry site that provided Aquia sandstone for the construction of the White House and the U.S. Capitol Building in Washington, D.C. The 1 mile hiking/walking trail, creeks, wetlands, and marsh area provide a variety of habitats for native and migratory birds and other wildlife. The elevated boardwalk through the wetlands and woods to the island offers a continuous, accessible viewing area. Fishing is not permitted from the island.
