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