Bull Run Occoquan Trail

The terrain is quite varied, featuring natural surfaces that can be rocky, rooty, and muddy, especially after rain. You'll encounter frequent, often steep, hills and stream crossings, with over 1,500 feet of elevation gain throughout the entire trail. While some sections are relatively level, it's generally considered moderate to moderately strenuous. The southern portion, particularly towards the Fountainhead Regional Park end, is known for its tougher climbs. Proper footwear is highly recommended.

Due to its length, varied terrain, and significant elevation changes, the full 18-19.7 mile trail is generally not recommended for beginners.

The central portion near Clifton, accessible close to Paradise Springs Winery, is often considered more scenic and family-friendly for those looking for an easier experience.
