Byway Overview
Mount Blue Sky (formerly Mount Evans) is not only the highest Colorado scenic byway, but is also home to the highest-paved road in North America! Climb more than 7,000 feet, reaching an altitude of 14,130 feet along this route. Although Mount Blue Sky feels like a national park, it is actually a wilderness area. This is due to laws enforcing roadless and non-motorized zones in the 1950s, which would become the Wilderness Act of 1964. By that time, the road to the top of the mountain was already partially built and became grandfathered in.
This is one of the best places in Colorado to catch a glimpse of the stately bighorn sheep. Climbing that high, that fast, remember that the weather is volatile at times. Be prepared for wind, rain, lightning, snow, and hail any day of the year.
Reservations are required for vehicle entry at Mount Blue Sky.
