Muddy Branch Trail


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.

Parts of the Muddy Branch Greenway Trail are still under construction, so please bear with the county while they install the bridges, signs and parking needed to make this trail a winner. If you’re interested in helping out, please contact the Volunteer Office.

For additional information, including elevation and downloadable GPS file, please visit the MTB Project Page.
