Black Marsh comprises almost half of North Point State Park, established by the Conservancy and Baltimore County in 1987. This 1,300-acre park on the shores of the Chesapeake Bay once served as a private retreat for Bethlehem Steel executives, but today belongs to all Marylanders, offering visitors a wading beach, fishing pier, hiking trails, and scenic overlooks.
