The 'Ma & Pa' nickname refers to the Maryland and Pennsylvania Railroad, which operated from 1901 to 1958.
The trail occupies portions of a historic rail bed that once connected York, Pennsylvania, to Baltimore, Maryland.
Several original stone bridge abutments and rail infrastructure fragments remain visible along the path.
The trail alignment crosses through Rockfield Park, which contains the historic Rockfield Manor site.
The pathway acts as a green corridor that preserves native vegetation and wildlife habitats within the town limits.
The Ma & Pa Heritage Trail is a linear rail-trail in Bel Air, Maryland, constructed along the former Maryland and Pennsylvania Railroad corridor. The trail features a paved surface that winds through wooded areas, across bridges, and past historic remnants of the defunct rail line. It serves as a multi-use pathway for walkers, runners, and cyclists connecting key parts of Harford County. The route traverses varied terrain including both flat sections and moderate inclines. It offers access to community parks and maintains a natural environment despite its proximity to the suburban center of Bel Air. The trail surface is primarily asphalt, providing year-round accessibility for non-motorized recreation.
The scenic bridge crossings within the wooded sections offer the most representative trail views.
Park at the Williams Street or Tollgate Road access points for the easiest entry.
Bring water as there are limited facilities directly on the trail path.
Be prepared for occasional shared-use traffic from cyclists and runners.
Do not attempt to hike off-trail into private property lines that border the rail corridor.
Leash your pets and clean up after them; yield to pedestrians if cycling.
