Lake Roland Park is a city/county park encompassing over 500 acres of woodland, wetlands, serpentine barrens, rare plants and rocky plateaus surrounding Lake Roland in Baltimore County, Maryland. The park is located near the intersection of Falls Road and Lake Avenue, adjacent to the Falls Road Light Rail Stop of the Baltimore Light Rail, which runs from Cromwell Station near Glen Burnie in Anne Arundel County in the south to Hunt Valley of Baltimore County. The line runs along a railroad embankment and trestle over the lake above the dam, cutting the park into a two-thirds wooded northern part and the one-third southern portion around the dam, picnic groves, pavilion and pumping station.
