Colorado boasts many roads that ascend high above the clouds. Most climb over mountainous passes; some summit 14,000 foot peaks. Many of these roads were built to access mining sites or small mountain towns, while others were built to allow people to see the magnificent views from the high alpine passes and peaks. A few of these roads are paved, but watch out for those more off the beaten path. Some will even require high-clearance 4WD vehicles to navigate the exposed and rocky switchbacks. Read on to see the highest 20 roads in Colorado and find out if your favorite makes the list.
