Patapsco Valley State Park extends along 32 miles of the Patapsco River, encompassing 14,000 acres and five developed recreational areas. Recreational opportunities include hiking, fishing, camping, canoeing, horseback and mountain bike trails, as well as picnicking for individuals or large groups in the park's many popular pavilions. The Avalon Visitor Center houses exhibits spanning over 300 years of history along the Patapsco River. Housed in a 19th century stone dwelling in the Avalon area, the center includes a re-creation of a 1930's forest warden's office. This is a Maryland State Park.
