At over 55 miles and with plenty of hills to climb, a few of which are significant, this is one of the more challenging country road routes in central Texas. With plenty of history and beautiful country, this is also one of the most enjoyable tours you can take on a bike. Road bikers especially will love the very low traffic through the rural route of Mormon Mill Road, where a stone quarry, ranches, and hunting grounds remain the primary uses of land in this area.
