From Chattanooga, take 27 North (following signs for downtown), across the Tennessee River. After about a mile, exit onto 127 North, and follow it to the base of Signal Mountain. Turn left on Suck Creek Road (27 West), follow it for four miles, cross over a bridge, and continue up the canyon.
The pulloff for the Upper Passes is on the right, about a mile past the aforementioned bridge. Scramble down the steep bank, cross the creek and hike up the landslide to the cliff base. The routes lie to the left of the slide.
To reach the Roadside Wall, continue up the canyon road about 1_ miles to an obvious pulloff on the right. Scramble down across the creek and up to the cliff base. Walk right to the first routes.
