The Donut Hole Trail heads north from Bucktail State Park through Kettle Creek State Park towards Tamarack. It then turns south in the Sproul State Forest towards Hyner, passing through Hyner Run State Park before continuing south to Farrandsville. This red blazed cross country trail traverses the northern most part of the Sproul State Forest. "The trail is diverse in that it has some level, some steep, some rocky sections, some side-hilling and so on. It has many areas where it follows old logging roads where it is very nice and wide. There are some areas which are overgrown and difficult to see the trail but still seems to be marked well enough to follow the blazes. When the trail goes by streams it often is rocky. There seems to be good access to water and several campsites including some dry campsites at viewpoints." - Dawn Hamilton, 10/1/2009.
