In southern Indiana, the 58 mile Knobstone Trail winds through thick woodlands and up steep ridgelines while traversing the rocky, forested Knobstone Escarpment. The Knobstone Escarpment has layers of weathered brown shale and sandstone have been heaved up to 300 feet above low-lying farmland and hollows.
The main route passes through Clark State Forest, Elk Creek Public Fishing Area, and Jackson-Washington State Forest in Clark, Scott, and Washington counties and is managed by the Indiana Department of Natural Resources. The white-blazed trail presently extends from near Deam Lake, just north of S.R. 60 in Clark County, to Delaney Park, just east of S.R. 135 in Washington County. Make sure to bring water since it can be very dry at times.
The Knobstone Trail may eventually be developed northward to connect with the Hoosier National Forest, Yellowwood State Forest, and Morgan-Monroe State Forest. The Hoosier National Forest currently manages an informal stretch of the Knobstone Trail in Brown County known as the Nebo Ridge Section.
Seven trailheads have been developed along the trail, providing parking areas and direct access to the Knobstone Trail. The Delaney Park Trailhead is located within Delaney Park, a Washington County Park that includes facilities for camping, cabins, showers, and a gated entrance. The Elk Creek Trailhead is located at a public access site on Elk Creek Lake. The parking area for the lake and trail is paved. All of the other trailheads include a small gravel parking area.

Delaney Park Loop (approximately 6 miles; distance to Spurgeon Hollow Trailhead is approximately 2, 7, or 9 miles depending on the route chosen) The Delaney Park Trailhead is located inside Delaney Park, near the beachhouse.
