Overview
Pinnacle Knob sits in the quieter interior of Daniel Boone National Forest, away from the Red River Gorge crowds and the geological spectacle of the arches. What it offers instead is a straightforward ridge climb to a genuine summit with long views across the forest's interior, a sense of solitude that is increasingly rare in this frequently visited forest, and a good workout on a well-defined trail.
The site once held a USFS fire lookout tower, part of the network of observation points that rangers used to spot smoke before aerial surveillance. The tower is gone but the clearing remains, and the views in multiple directions make the climb worthwhile.
The Route
Miles 0.0 to 0.8: Trailhead to Ridge
The trail begins on a forest road pullout and immediately enters mixed hardwood forest on a moderately steep grade. The first 0.8 mile gains the most elevation as the trail climbs to the main ridge.
Miles 0.8 to 1.4: Ridge to Summit
Once on the ridge, the trail levels briefly before making the final push to the summit clearing. The forest transitions to drier pine and oak as the ridge narrows. The summit clearing opens abruptly at mile 1.4.
Miles 1.4 to 2.8: Return
The return follows the same route. The descent is straightforward with good footing throughout.
When to Hike
April through May is excellent for spring warbler migration. The open summit attracts migrating birds and the forest below is alive with species moving through.
September through November provides clear views and fall color across the interior ridges. Less visitation than the Gorge trails at any time of year.
June through August the summit can be warm and exposed. An early morning start in summer keeps temperatures manageable.
December through March delivers the clearest long-distance views when leaves are off the trees.
What to Bring
Many hikers carry 1.5 liters of water for this hike; there is no water source on the trail. The summit is exposed so sun protection matters in summer. Binoculars enhance both the distance views and the birding opportunities. Trekking poles help on the descent on the steeper lower section.
Trailhead Access
The Pinnacle Knob trailhead is accessed via unpaved forest roads in the Morehead Ranger District area. No fee to park or hike (as of 2026). No facilities at the trailhead. High-clearance vehicles are recommended for the access road in wet conditions; passenger cars with careful driving can typically manage in dry weather. No overnight camping at the trailhead; dispersed camping is available at suitable sites along the approach road.
Nearby
Rock Bridge Trail and Koomer Ridge Sheltowee Loop are in the Red River Gorge section of the forest, a different character from Pinnacle Knob but accessible in the same day trip from Lexington.
Before visiting this more remote trailhead, check road conditions at checking conditions before you go, as forest road access can be impacted by seasonal closures or washouts. Practice Leave No Trace principles at the dispersed camping sites near the access road.
