"This loop hike has a lot of ups and downs, literally. Leave the Grays Arch trailhead and enjoy some views before coming to the massive stone feature for which this loop is named. Grays Arch is one of the biggest draws in the Red River Gorge, and deservedly so. The arch is in an alcove where water falls from a ledge, massive boulders lie still among the rhododendron, and rock shelters look out on the scenery.
Beyond the arch, this loop picks up the Rough Trail and drops into King Branch, only to climb out and descend again to Rush Branch. Climb from Rush Branch to meet the Sheltowee Trace, which will take you back to the trailhead. Outstanding Features: Grays Arch, King Branch, rockhouses, views, and waterfall."
