How Long is the Million Dollar Highway?
The Million Dollar Highway covers 25 miles (40 km) between Silverton and Ouray. It’s also part of the larger San Juan Skyway Scenic Byway, a 236-mile loop through the San Juan Mountains.
If you’re starting in Durango, the drive to Silverton adds another 45 miles, so plan on about 70 miles one way from Durango to Ouray. Between Durango and Silverton, the highway roughly parallels the famous Durango & Silverton Narrow Gauge Railroad, another classic Colorado adventure.
Location of Colorado’s Million Dollar Highway
Although the entire 25-mile stretch carries the nickname, the most dramatic section is the 12 miles south of Ouray through Uncompahgre Gorge up to Red Mountain Pass. This part of the road has:
- steep cliffs,
- sharp hairpin turns,
- narrow lanes,
- and no guardrails.
It sounds intimidating, but don’t worry—with caution and preparation, it’s very doable. Honestly, we found it far easier to drive than Hawaii’s Kahekili Highway on West Maui.
High Passes Along the Million Dollar Highway
When you drive the Million Dollar Highway, you’ll cross three spectacular mountain passes:
- Coal Bank Pass – 10,640 ft (3,243 m)
- Molas Pass – 10,970 ft (3,344 m)
- Red Mountain Pass – 11,018 ft (3,358 m)
Each pass delivers sweeping views of the San Juan Mountains, with plenty of spots to pull over for photos.
Interesting Facts & History of the Million Dollar Highway
The Origin of the Name
The name Million Dollar Highway has sparked debate for decades. Some say it cost a million dollars per mile to build back in the 1920s. Others believe the roadbed itself contains a million dollars’ worth of gold ore.
A third theory claims the name comes from the million-dollar views along the route—and that’s the version we like best.
A Glimpse Into Its History
The story of this road goes back to 1883, when entrepreneur Otto Mears built the first toll road between Ouray and Ironton. Soon after, another toll road was added over Red Mountain Pass to reach Silverton.
Mears also turned to railroads, building the Silverton Railroad to connect Silverton with the booming Red Mountain mining district. However, the final eight miles to Ouray were so rugged and steep that even a cog railway never got past the planning stage.
By the early 1920s, Colorado invested heavily to rebuild the rough toll roads into a proper highway. In 1924, the Million Dollar Highway officially opened as part of U.S. 550. Today, this stretch forms the most dramatic section of the 235-mile San Juan Skyway Scenic Byway, one of the best road trip loops in the entire U.S.
Tips for Driving the Million Dollar Highway in Colorado
Use a Self-Driving Audio Tour
One of the best ways to experience this road is with a self-driving audio guide. The app is inexpensive and adds so much to the journey. As you drive, you’ll hear stories about the gold rush mining towns, the highway’s visionary builder Otto Mears, and the dramatic San Juan Mountains around you.
The app highlights all the major stops and viewpoints, working as your guide, map, and audio tour rolled into one.
Always Check the Weather
Conditions on the Million Dollar Highway can change quickly. Rain, snow, or sudden storms can make the road slippery and dangerous. Avalanches and landslides are also possible in some sections.
Before you set out, check the latest weather and road reports. If a storm rolls in, don’t push through—stop and wait it out. Driving this road is safest and most enjoyable in clear daylight conditions.
Take Your Time
This is not a highway to rush. The views are the real highlight, so drive slowly and enjoy them. If you want photos, only pull over in safe, designated spots. Plan to drive in the daytime when visibility is best and the scenery is at its most dramatic.
Drive South to North
We recommend driving from south to north, starting in Durango or Silverton and ending in Ouray. This direction offers the most dramatic views. The descent from Red Mountain Pass into the Uncompahgre Gorge delivers sweeping panoramas, and it’s easier to stop at pullouts for photos.
How Long Does It Take to Drive the Million Dollar Highway?
The 25-mile stretch between Silverton and Ouray may not sound long, but plan at least 2–3 hours with photo stops in both towns. The drive itself is stunning, and you’ll want time to pull over and enjoy the views.
If you’re starting in Durango, the route is about 70 miles and usually takes 4–5 hours with stops. We suggest making it a full-day trip so you can relax at the end in the Ouray Hot Springs.
If you have more time, extend your adventure into a 2–3 day road trip and complete the full San Juan Skyway Scenic Byway loop (235 miles). It’s one of Colorado’s most beautiful drives.
When Is the Best Time to Drive the Million Dollar Highway?
The Million Dollar Highway is open year-round, but the experience changes drastically with the seasons.
- Summer (June–September): Warm and dry, with highs between 70–90°F (21–32°C) in the valleys and 50–70°F (10–21°C) in the passes. This is the most popular time to drive.
- Fall (October): Gorgeous golden aspens, but snow can arrive early in the mountains.
- Winter (November–April): Cold and snowy, with average lows in Ouray dropping to 2.8°F (-16.2°C) in December. The area averages 134 inches of snow per year (well above the U.S. average of 28 inches). Expect icy roads, limited visibility, and possible closures. Chains may be required.
- Spring (May): Snow often lingers at higher elevations. Roads can be slippery, and conditions unpredictable.
Drive between June and October for the safest and most scenic conditions. Always travel in daylight, check road status before you go, and prepare for sudden weather changes with extra layers.
Agnes’ Advice: We drove in early May, and the snow made the road slippery with poor visibility. It was still beautiful, but challenging. For the best experience, wait until summer or early fall.
What Are the Most Dangerous Sections of the Million Dollar Highway?
The Million Dollar Highway is one of the most scenic drives in Colorado, but parts of it are also notorious for their sharp curves and narrow lanes carved directly into the mountains. The road twists through canyons and along steep cliffs, offering both breathtaking views and a few white-knuckle moments.
The good news? If you drive slowly, stay alert, and respect the road, you’ll be fine. Families and road-trippers make this drive every day. Just take your time and enjoy the scenery.
Uncompahgre Gorge
One of the trickiest sections is the stretch through Uncompahgre Gorge. Here, the road hugs the cliffside with little room for error. You’ll face steep drops, narrow lanes, and almost no guardrails.
The climb toward Red Mountain Pass adds to the challenge, with a series of sharp S-curves designed to gain elevation. Many of these lanes are literally cut into the rock face.
Red Mountain Pass
At 11,018 feet, Red Mountain Pass is the most dramatic—and dangerous—part of the drive. The north side heading toward Ouray is especially challenging, with an 8% grade, tight switchbacks, and winding curves. Shoulders are minimal, guardrails are scarce, and the slopes are steep.
Winter adds more risk. This area is prone to avalanches and heavy snow, and snowplows push the ice and snow directly over the edge, which is why guardrails are absent in many places.
Despite its reputation, Red Mountain Pass is also one of the most historic spots on the highway. The first gold wagons crossed here in 1878, opening the route that would later become one of Colorado’s most famous drives.
Highlights Along the Million Dollar Highway in Colorado
Driving the Million Dollar Highway is more than just a road trip—it’s an adventure through some of Colorado’s most breathtaking landscapes. The route winds past Uncompahgre Gorge, Idarado Mine, the Animas River, San Juan National Forest, Elektra Lake, Twilight Peak, and Red Mountain Pass. You’ll also pass through historic mining country, where remnants of the past still cling to the hillsides.
Don’t miss quirky roadside stops like Pinkerton Hot Springs with its colorful mineral deposits. Another fun detour is Baker’s Bridge, where Paul Newman and Robert Redford made their iconic leap in Butch Cassidy and the Sundance Kid. Along the way, you can also pause at Haviland Lake and take in sweeping views from Molas Pass.
Stop in Silverton, Colorado
Silverton feels like a town frozen in time. Walking down its streets is like stepping back 100 years. The town is listed as a National Historic Landmark and serves as the gateway to the Animas Forks ghost town and the Alpine Loop backcountry drive. In summer, the Durango & Silverton Narrow Gauge Railroad brings visitors here daily.
Outdoor lovers will find endless activities nearby. In winter, Silverton is a hub for snowmobiling, skiing, ice climbing, and even ice fishing. In summer, you can go rafting, hiking, biking, horseback riding, or camping in the surrounding wilderness. At the very least, set aside an hour to stroll the historic streets and admire the colorful facades and shop windows.
Visit Ouray — The Switzerland of America
At nearly 8,000 feet, Ouray sits in a river valley surrounded by the jagged San Juan Mountains, earning its nickname: The Switzerland of America. This charming mountain town is also known as the outdoor recreation capital of Colorado.
Much of its historic character remains intact, with beautiful architecture, lively restaurants, cozy bars, and plenty of shops. It’s the perfect base for further adventures in southwest Colorado.
Soak in Ouray Hot Springs
After the twists and turns of the Million Dollar Highway, nothing beats soaking in Ouray Hot Springs. These geothermal pools have been used for centuries, first by the Ute people. Today, the modern complex includes five pools, three of them naturally heated, with temperatures ranging from 75°F to 104°F.
The water is packed with minerals like iron, manganese, zinc, and potassium—but without sulfur, so there’s no odor. The pools are family-friendly, affordable, and surrounded by dramatic 13,000-foot peaks, making them the ultimate spot to unwind.
Extend Your Drive on the San Juan Skyway
If you have more than a day, consider driving the entire San Juan Skyway National Scenic Byway. This 235-mile loop takes about 6–7 hours without stops, but you’ll want at least two or three days to enjoy it fully. From Ouray, you can continue through Old West towns like Ridgway, Telluride, Rico, Dolores, and Cortez.
This longer route combines rugged mountains, mining history, and charming towns—making it one of the best road trips in the United States.
Final Thoughts on Driving the Million Dollar Highway
The Million Dollar Highway is one of the most unforgettable drives in the United States. With its towering peaks, hairpin turns, and jaw-dropping views, this short stretch of road packs in more beauty than many longer routes.
Take your time, drive carefully, and stop often to enjoy the scenery. Towns like Silverton and Ouray add charm, history, and great places to relax after the drive. If you have more days, extending your trip along the San Juan Skyway makes the adventure even richer.
For us, this road felt like the heart of Colorado’s wild beauty—dramatic, challenging, and rewarding. If you’re planning a Colorado road trip, the Million Dollar Highway deserves a spot at the very top of your list.
