Muddy Branch Greenway Trail

Muddy Branch Greenway Trail Locator


The 9 miles of Montgomery County’s newest multi-use natural surface trail are accessible to most users, but they aren’t flat or boring by any means. The trail traverses varied terrain and ecosystems including rocky upland forest, streambanks and meadows, and passes by rich vernal pools, earthen mill remnants and the Potomac Horse Center and on its way from Darnestown Road in Gaithersburg down to historic Blockhouse Point Conservation Park. A brand new bridge now allows users to cross over to Pennyfield Lock and the C&O Canal.

If you’re interested in helping maintain this trail, please contact our Volunteer Office.

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.
