Does a short, narrow, white-knuckle 4WD climb sound like a thrill? Then Radical Hill might be the trail for you. This intense trail begins with a few rock obstacles to test your vehicle's ability before testing your own mental ability on the narrow switchbacks up Teller Mountain. Be sure to stop and check out the cabin before you work your way up. Once you reach the summit, enjoy 360-degree views of the mountain peaks, including many surrounding trails like Red Cone.
