Liberty Reservoir is in the suburbs of Baltimore and divides Baltimore County and Carroll County. The reservoir is open to a variety of outdoor recreational activities. At its northern end, the lake is narrow and in times of plentiful rain, completely fills the small canyon of the Patapsco River’s North Branch. The lake edge runs up against steep slopes that rise 200 feet and small feeder streams cascade down through narrow gorges into small coves, making for stunning scenery. There are eight steep climbs on this route but none are more than about 150 feet. Limited parking is available on the side of Glen Falls Road.
