This route was planned by komoot.
While the overall Gerry Connolly Cross County Trail is sometimes rated easier, this specific section is considered moderate by komoot, and often described as more challenging than other parts of the trail. Hikers should expect a rugged experience with natural dirt paths, steep slopes, and narrow passages. It requires good fitness, especially if considering the full stage to Great Falls Park.
The terrain is largely natural and rugged, featuring dirt paths, stream valleys, high bluffs, and creek-side single-track. It can become quite muddy after heavy rains and may involve shallow fords. Expect steep slopes and narrow passages, making it feel wild and rewarding.
The trail immerses you in green, shaded stream valleys and hardwood forests, often described as a 'fern-sheeted gorge.' You'll follow the picturesque Difficult Run River, and the northern terminus of the larger trail system leads to the dramatic vistas of Great Falls Park. Keep an eye out for diverse wildlife, including deer, foxes, muskrats, amphibians, and various bird species like hawks and owls. Notable points include the Cross County Trail – Section 7: Difficult Run Stream Valley and the Difficult Run Stream Valley itself.
Yes, the trail is generally dog-friendly. However, due to the rugged terrain, steep sections, and potential for mud and shallow stream crossings, ensure your dog is fit for the hike and always keep them on a leash. Be mindful of other hikers and wildlife.
Spring and fall are generally the best seasons for hiking this trail, offering pleasant temperatures and beautiful foliage. Summer can be hot and humid, while winter may bring icy conditions on steeper sections. Be aware that after heavy rains, the trail can become very muddy and involve shallow fords, regardless of the season.
No, there are typically no permits or entrance fees required to access the Gerry Connolly Cross County Trail or the Difficult Run Stream Valley Park section. It's part of the Fairfax County park system, which generally offers free access to its trails. However, always check the official Fairfax County Park Authority website for any updates or specific regulations.
Parking options are available at various access points along the Gerry Connolly Cross County Trail. For the Difficult Run section, you might look for parking near the CCT Trail Entrance at Miller Heights Road or other designated trailheads in the vicinity. Specific parking availability can vary, so it's advisable to check local maps or park authority websites before your visit.

Along the Difficult Run section, you'll cross several interesting features. Keep an eye out for The Burnett bridge and The Swan Family Bridge. There are also several Creek Access Point and CCT Stream Crossing points, which can involve shallow fords, especially after rain.
Due to its rugged terrain, steep slopes, and potential for mud and stream crossings, the Difficult Run section is generally considered more challenging than other parts of the Gerry Connolly Cross County Trail. It might be less suitable for very young children or those unaccustomed to strenuous hiking. Families with older, experienced children who enjoy a more adventurous hike may find it rewarding.
While the Difficult Run section itself is quite natural and immersive, being within Fairfax County means there are various dining options in nearby towns and communities. You'll likely need to drive a short distance from the trailheads to find restaurants, cafes, or other amenities.
Given the trail's natural and sometimes rugged character, it's recommended to bring sturdy hiking boots, plenty of water, snacks, and appropriate clothing for the weather. Trekking poles can be helpful for stability on steep or muddy sections. A map or GPS device is also advisable, as cell service can be spotty in some stream valleys.
