Overview
The Knobstone Trail is Indiana's longest hiking trail at 35 miles, running through the Knobstone Escarpment: the most topographically rugged terrain in the state. The north section covers 9 miles from the Delaney Park trailhead south into the edge of the Charles C. Deam Wilderness in Hoosier National Forest, with sustained ridge climbing, creek crossings, and a wild character that is genuinely surprising for a Midwest trail.
The escarpment consists of northeast-trending ridges carved from shale and siltstone, with knob summits reaching 700 to 800 feet above the surrounding Indiana lowlands. The views from the ridge tops in bare-tree season extend for miles across the rolling southern Indiana countryside.
The Route
Miles 0.0 to 2.5: Delaney Park to First Ridge
From the Delaney Park trailhead, the trail enters the escarpment forest immediately and begins its characteristic pattern: steep climb to ridge, brief ridge traverse, steep descent to creek, repeat. The first ridge climb gains 450 feet over 0.8 miles. The ridge views open in bare-tree season before the trail descends to the first creek crossing (stepping stones in dry season, wading in spring).
Miles 2.5 to 5.5: Central Ridge Traverse
The central section hits the most sustained ridgeline walking on the segment with two additional significant climbs. The forest is mature oak-hickory on the ridge tops and transitions to tulip poplar and maple in the creek hollows. Excellent spring wildflower variety in the hollows: trillium, wild ginger, Dutchman's breeches, and spring beauties. Two more creek crossings on this section.
Miles 5.5 to 9.0: Deam Wilderness Approach
The southern section enters the boundary of the Charles C. Deam Wilderness and becomes increasingly remote-feeling. Trail maintenance drops slightly inside the wilderness boundary. The final creek crossing at mile 7.8 can be thigh-deep after heavy spring rain. The southern trailhead is at a gravel lot near the wilderness boundary.
When to Hike
April through June: Spring wildflowers peak in April and May. Creek crossings are highest but manageable. Best wildflower diversity on the trail.
October and November: Ridge views at their clearest after leaf drop. Hunting season begins in November: blaze orange required.
Summer: Hot and humid in southern Indiana. The creek hollows provide shade but the ridge tops are exposed. Carry extra water.
What to Bring
Many hikers carry 2 to 2.5 liters of water for the full section. Creek water requires treatment. Waterproof footwear for creek crossings in spring. Trekking poles are very helpful on the steep ridge climbs. For overnight trips, a stove is recommended over campfires in the wilderness area.
Trailhead Access
Northern trailhead at Delaney Park on Delaney Park Road. Southern trailhead at the Deam Wilderness boundary on Jefferson County roads. Both have free parking, no facilities. No permit required for day hiking or dispersed camping (as of 2026). Dogs welcome on leash.
Nearby
The Mogan Ridge Loop is another rugged option in the Perry County wilderness unit. The German Ridge Trail is a more accessible loop in the southern unit. Before any backcountry trip on the Knobstone, check current conditions for creek levels and trail closures. Review Leave No Trace principles for dispersed camping in the Deam Wilderness.
