MD 25 enters the Bare Hills Historic District and Bare Hills area of Baltimore County. The state highway crosses over the Baltimore Light RailLink line again and the Jones Falls next to the Falls Road station. The station is accessed via unsigned MD 746 (Lakeside Drive), which partially runs underneath MD 25 along the latter highway's overpass on its way to the station parking lot. The state highway ascends from the stream valley and curves northwest between Robert E. Lee Memorial Park (a Baltimore City park located just barely in Baltimore County) with its historic Lake Roland and dam from the old 1860 city waterworks system to the northeast and the Bare Hills House on the southbound side of the highway. MD 25 continues north through a well-forested affluent area between Towson (county seat of Baltimore County) to the east and Pikesville to the west with its headquarters for the Maryland State Police. The highway descends to and crosses Jones Falls twice on either side of an underpass of I-83. To the north of the second crossing of the stream, MD 25 has a four-leg intersection with MD 133 (Old Court Road) and Ruxton Road; the latter road has a half-diamond interchange with I-83 that allows access to and from Baltimore. North of MD 133, the highway passes the Rockland Historic District and the historic home "Rockland" in the community of Brooklandville.
