Mount Blue Sky Scenic Byway

Colorado Highway 5

Idaho Springs, CO

A paved road that keeps climbing until it runs out of mountain, to the highest point any car can reach in North America.

Mount Blue Sky Scenic Byway does something no other road in North America does: it drives you, in an ordinary car, from a mountain town at around 7,500 feet all the way to above 14,000 feet, on pavement the whole way. In its roughly 28 miles it climbs more than 7,000 vertical feet, leaving the pines behind for the treeless alpine tundra, and finishing just short of the 14,271-foot summit of the peak. Nothing else you can simply point a car up gets this high.

The road is an artifact of an unusual era. In the 1920s Colorado wanted to outdo the famous Pikes Peak Highway and pull tourists toward Denver, so it set out to build the highest automobile road in the world. Construction began in 1923 and the road opened at the start of the 1930s, and by finishing just above the Pikes Peak road it claimed the title of highest paved road on the continent, a title it still holds today.

What Guests Love

  • Driving all the way to above 14,000 feet, the highest a car can go in North America
  • Mountain goats and bighorn sheep that graze right beside the road near the top
  • Ancient bristlecone pines, some among the oldest living things on earth
  • The mirror-still alpine lakes and the enormous views down the Continental Divide

Worth Knowing

  • The upper road is only open in the warm months and closes with the first heavy snow, so it is a summer and early-fall drive
  • At over 14,000 feet the air is thin and the weather changes fast, so bring layers even on a warm day and watch for afternoon storms
  • The final stretch is narrow with steep drop-offs and no guardrails in places, so drive slowly and let faster cars pass
  • A timed-entry reservation is usually required in summer, so plan ahead rather than showing up on a whim

Learn about Mount Blue Sky Scenic Byway

A road built to win a rivalry

The byway was born of civic competition. Colorado Springs had its Pikes Peak Highway drawing crowds, and Denver wanted a mountain of its own to lure the growing wave of automobile tourists in the 1920s. The answer was to build a road up the great peak west of the city, and to build it higher than anything else in the country, high enough to be the highest in the world when it opened.

Crews began work in 1923 and pushed the road up through forest and then across the fragile alpine tundra, a hard and slow job at altitude, and it opened to the public at the start of the 1930s. The engineering feat of laying pavement across ground that spends much of the year buried in snow and battered by wind is part of what makes the drive feel improbable even now.

The peak and its byway were renamed to Mount Blue Sky in recent years, honoring the region's Cheyenne and Arapaho heritage and setting aside a name tied to a figure from the state's darker past. The road itself, and the astonishing height it reaches, is unchanged.

Climbing through the life zones

One of the quiet pleasures of the drive is watching the world change as you rise. You start in the montane forest of pine and aspen, pass mountain lakes cupped in glacier-carved basins, and then break above the tree line into the alpine tundra, a low, tough carpet of grasses and tiny wildflowers that survive one of the harshest environments in the lower states.

Up here you meet the residents. Herds of mountain goats and bighorn sheep are often right beside the road near the top, unbothered by cars, and yellow-bellied marmots sun themselves on the rocks. In July the tundra can be dotted with alpine wildflowers that bloom in a rush during the few warm weeks they get.

Near the upper reaches grow Rocky Mountain bristlecone pines, gnarled and wind-sculpted, some of them thousands of years old and among the oldest living organisms on the planet. To stand beside a tree that was already ancient when Rome was young, at the edge of the sky, is the kind of thing this road quietly offers.

Driving it well

This is a drive to take slowly and respectfully. The upper road is narrow and switchbacks tightly, with steep drop-offs and stretches without guardrails, so keep your speed down, use the pullouts, and let anyone in a hurry go past. The reward for patience is a long list of places to stop, from the lakes on the way up to the summit parking area at the top.

The altitude is real. Above 14,000 feet the air holds far less oxygen, so take it easy, drink water, and give yourself time to acclimate rather than sprinting up the short summit trail. Weather at the top can swing from sunny to snow and lightning in a single afternoon even in midsummer, so pack warm layers and rain gear, and be ready to turn back if a storm builds.

The road only opens for the warm season, roughly late spring into early fall, and closes with the snow, and in recent years a timed-entry reservation has been required in peak months. Plan the trip in advance, aim for a clear morning, and you get one of the most extraordinary short drives in the country, ending quite literally at the top of the paved world.
