Northwest Branch Trail

When completed, the Rachel Carson Greenway trail corridor will span 25 miles stretching from the historic Adelphi Mill in Prince George's County north to Patuxent River State Park. Just south of the Burnt Mills trailhead, the trail showcases the ruggedness of the wilderness in an urban setting with old growth trees and rock scrambles. North from here the trail travels a corridor of natural and cultural significance through suburbs and terminating in rural farmlands in the county Agricultural Preserve.

We have already started highlighting the existing trails in the corridor with with educational interpretive signs (PDF, 2MB) relating to our county's environmental, historical and cultural heritage.

Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are "Shared by All" trails which includes hikers, bikers and equestrians. Additional information about permitted uses of Park trails is available on our Trail User Information page. <br><br><a href="http://www.montgomeryparks.org/PPSD/ParkTrails/trails_MAPS/Rachel_Carson_Greenway_trails.shtm" target="_blank" rel="">Click to Learn more</a>
