The Davis Run Loop Trail at Keystone State Park, Pennsylvania, is a moderate 3 mile hike that starts on the northeastern side of Keystone Lake and runs toward the eastern corner of the park before looping back.

The trail starts out by heading toward the wetland area of Keystone Lake before heading uphill and winding through deciduous trees and some small patches of evergreens and pines.

Follow the yellow blazes and check your map often since there are various ways you can hike on this loop. There are a few connector trails that run between the main loop, so either stay left or stay right on the loop depending on which direction you hike the loop in. There are some signs along the trail that you can follow back to the trailhead, but note that almost all of the trails at Keystone State Park use yellow blazes, which can make this hike confusing.

Dogs are allowed if leashed.

Biking is prohibited on all of the trails at Keystone State Park.

Parking can be found directly across the street at the main parking lot on the northeast side of Keystone Lake.

very confusing without a map, the trailheads all had different colors and I have no clue which trail we were actually on. Besides that, it was a beautiful hike. There were a few fallen trees, but it was well maintained besides that. Park at the main "beach" of the lake, by the playground, and walk across the street towards the bridge to start on the trail.
