There's a trail that climbs up to the summit of Mount Yonah. It gains about 1,400 feet of elevation in a fast 2.5 miles. There's a gorgeous view off the top of the rock face, and if you are into climbing, opportunities abound for easy-to-hard sport climbing, top roping, bouldering, and trad climbing.
Head north from Cleveland on Highway 75. Turn right Tom Bell Road. Go down a little ways and hang a left onto McGee Dr. Turn right onto Chambers Rd. and then turn left onto the gravel road up to the parking lot.
