Sweeping south around the west side of Sylvan Lake, Brush-Gypsum Road is an all dirt connecting route between the towns of Gypsum and Thomasville, located along section 4 of the Colorado Backcountry Discovery Route (COBDR). The Colorado Backcountry Discovery Route is a mostly dirt route across Colorado connecting Wyoming and New Mexico. Created primarily around motorcycles, the entire route follows mainly 4wd roads and two tracks over the course of about a week. This road treks through thick tree cover and has a number of large, mature aspen groves making it a great place to see fall colors.
