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.

MD 25 crosses over I-695 (Baltimore Beltway) then passes "The Cloisters" (former Baltimore City children's museum) and the Brooklandville House before crossing Jones Falls one last time at the east end of the Green Spring Valley as the highway enters Brooklandville.
MD 25 has a ramp to the Jones Falls Expressway as the road begins to parallel the expressway.
The highway, which is unsigned MD 25A north of I-695 (at which point I-83 continues east on I-695 to follow the Baltimore-Harrisburg Expressway), has its northern terminus at an orthogonal intersection with MD 25 and Joppa Road, which heads east toward Towson.
MD 25 makes a sharp turn east at the north end of the parallel section, then turns north onto a four-lane divided highway extending north from the freeway.
The highway passes through a commercial area to MD 130 (Greenspring Valley Road), north of which the highway becomes two lanes again.
At the northern end of Brooklandville, the state highway meets the western end of MD 131 (Seminary Avenue) and passes by the campuses of Maryvale Preparatory School and Episcopal Church twin institutions, St. Paul's School (for boys) and St. Paul's School for Girls, founded by Old St. Paul's Church in downtown Baltimore at North Charles and East Saratoga Streets, the area's oldest church, founded 1692.
MD 25 continues through the region of estate homes until the highway reaches Shawan Road and Tufton Avenue at the hamlet of Shawan, north of which the landscape shifts to farmland.

MD 25 crosses Western Run and passes through the village of Butler, where the highway meets MD 128 (Butler Road).
The highway follows Blackrock Run and Indian Run through a pair of ridges.
At the second ridge, MD 25 has a Y intersection with MD 88 (Black Rock Road) at Coopersville.
The state highway crosses Blackrock Run again and intersects MD 137 (Mount Carmel Road) at Whitehouse between Hampstead and Hereford.
MD 25 reaches its northern terminus at Beckleysville Road west of Beckleysville and Prettyboy Reservoir near the Baltimore–Carroll county line.
Falls Road continues northwest for 4.2 miles (6.8 km) as a county highway into northeastern Carroll County.
Just north of its intersection with Hoffmanville Road near Alesia, the highway becomes a narrow gravel road.
Falls Road has a grade crossing of CSX's Hanover Subdivision, then becomes a paved road again shortly before its northern terminus at Schalk Road No.
