This is from our trip to Hells Hollow in the Spring.
Hells Hollow Trail is an "easy" 0.5 miles (0.80 km) hiking trail that begins at the Hells Hollow parking area and follows Hell Run along the Slippery Rock Creek to the restored lime kiln and on to Hells Hollow Falls. The trail is part of the North Country Trail. The section in the park begins at the Alpha Pass scenic view. It then runs along the east bank of Slippery Rock Creek to the Old Mill and then on to Hells Hollow.
Check out our trip earlier this year and read about the legend of Hells Hollow.
