Siltstone Trail, Jefferson Memorial Forest

The Siltstone Trail is a long, point-to-point footpath through Jefferson Memorial Forest, a large Louisville Metro Parks woodland in the Knobs south of the city in Kentucky, United States. The Welcome Center trailhead sits at 11311 Mitchell Hill Rd in Fairdale, roughly 16 miles (26 km) south of Downtown Louisville. Visitors drive or take a rideshare, since no public transit reaches the forest, and parking is available at the Welcome Center and at the Scotts Gap trailhead at the far end. No fee was listed for the trail itself, though visitors should confirm current rules with Louisville Metro Parks.

The route runs about 6.7 miles (10.8 km) one way and typically takes 3.5 to 5 hours. The terrain is a sequence of forested ridges and hollows, with repeated climbs and descents rather than one sustained ascent, so cumulative effort is higher than the distance suggests. The tread is mostly packed dirt with rocky and root-covered stretches, and a few steep pitches that can be slick after rain. Tree cover is almost continuous, which keeps temperatures down in summer but also limits views except when leaves are off in late fall and winter, when the surrounding Knobs open up.

Because the trail is point-to-point, hikers either arrange a two-car shuttle between the Welcome Center and Scotts Gap or walk an out-and-back section and return the same way. Sensible turn-around points are any of the ridge saddles roughly midway, chosen by remaining daylight and water. The Welcome Center has restrooms and a place to check maps, but there are no restrooms at Scotts Gap or along the trail itself, and no reliable drinking water on the route, so hikers carry at least 2 liters. Ticks and insects are common in warm months, and a map or offline GPS is advisable because side trails and forest roads cross the route. Mid-October to November and March to May offer the most comfortable conditions.
