If getting high is your thing, Colorado offers some of the tallest mountains passable by motorcycle in the US. With several passes over 12,000 feet, there is no shortage of views on this route, just shortness of breath while taking in the sights in the thin air of Ophir, Corkscrew, Hurricane, California, Cinnamon, Cumberland, Cottonwood, Weston and Hagerman passes.
Beginning in the four corners location where, CO, AZ, NM and UT intersect, this 682-mile route winds its way north through the Rocky Mountains to the Wyoming border. The terrain includes dirt roads with rocks, sand and even a few water crossings to keep it exciting.
Best time of year: July through September. Most of the route can be done in late June. Depending on snowpack you might not make it through some high passes until sometime in July.
