Detour for Valley Creek Trail and Horse-Shoe Trail

A contractor will be on site in mid-December 2025 to conduct geotechnical investigation work as part of the rehabilitation of Valley Creek Trail after impacts from Hurricane Ida.

A short section of Valley Creek Trail / Horse-Shoe Trail will be closed while work is being completed. A detour route following the Horse-Shoe Trail and the Colonial Springs Trail will be in effect while the closure is in place.

The closure and detour will likely only be in effect for one day.

Trail Maintenance on the Fatlands and Chapel Trails

Ongoing trail maintenance on the Fatlands Trail (formerly called the River Trail) between Betzwood picnic area and the Fatlands Trail parking lot along Pawlings Rd, and on the Chapel Trail between Sullivan's Bridge and Washington's Headquarters is being conducted by park staff.

Work on the Fatlands Trail includes widening the trail to a standard 8 feet and relocating sections of the trail where the banks of the Schuylkill River are encroaching. Work on the Chapel Trail includes building new check steps and trimming vegetation.

The Fatlands and Chapel trails remain open to hikers, cyclists, and horseback riders, but all trail users are encouraged to use extra caution while maintenance work is ongoing.

Tips for Visiting the Park Safely

  • Recreate Responsibly. Follow local area health orders, practice Leave No Trace principles, and avoid crowding and high-risk outdoor activities.

  • Park in Designated Locations. Vehicles parked illegally will be ticketed, and vehicles that block emergency vehicle access (such as on roads or in front of gates) will be towed.

  • Plan to Pack Out Your Trash. In-park trash and recycling receptacles are limited.
