The visitor's center is off Powder Mill Rd, is between Rt. 1 in Beltsville and Rt. 197. The easiest access is from the Baltimore-Washington Pwy North off Beltway, 2nd exit going east, will be on your right in about a mile (?). (We don't go that way but I think these directions will get you there). There's a long entrance road -- the lake is Redington Lake. Gail Mackiernan
