About the Million Dollar Highway Drive
The Million Dollar Highway (US-550) is a 25-mile segment of the San Juan Skyway between Silverton (elevation 9,318 feet) and Ouray (elevation 7,792 feet) in southwestern Colorado. The road earned its name either from the gold ore in the gravel used to build it, or from the million dollars per mile it cost to construct — nobody agrees. The highway climbs over three mountain passes: Coal Bank Pass (10,640 feet), Molas Pass (10,910 feet), and Red Mountain Pass (11,018 feet). The most harrowing section descends from Red Mountain Pass to Ouray with no guardrails, sheer drop-offs of hundreds of feet, and tight switchbacks blasted from red and orange rock. Molas Lake (near Molas Pass) reflects the Grenadier Range on still mornings. The ghost town of Ironton, a mining settlement abandoned in the 1960s, sits in a valley between Red Mountain Pass and Ouray.

Fuel, Food & Services
Fuel up in Durango, Ouray, or Montrose. Silverton has seasonal fuel and food (mainly May-October). There is NO fuel on the 25-mile Silverton-Ouray stretch itself. Carry water and snacks; the canyon section has no services. Cell coverage is intermittent to absent over Red Mountain Pass and through the gorge.
Road Conditions
Narrow two-lane mountain road with tight switchbacks, grades up to about 8%, and long sections with NO guardrails over sheer drop-offs, especially north of Red Mountain Pass above the Uncompahgre Gorge. No tunnels. Three high passes: Coal Bank (10,640 ft), Molas (10,910 ft), and Red Mountain (11,018 ft). Avalanche paths are active in winter and the road is frequently closed for control work. Watch for falling rock and tight curves near Ouray. Drive slowly and use pullouts to let faster traffic pass.
Best Season to Drive
Late May through October for clear, snow-free driving. July and August offer wildflowers and reliable pass access; fall aspen color peaks in late September. The road stays open year-round, but winter brings frequent avalanche closures, ice, and no guardrails — not recommended for inexperienced winter drivers.
RVs & Trailers
Passenger cars handle the route fine in good weather. RVs and trailers can legally drive it, but the tight switchbacks, narrow lanes, and lack of guardrails make it stressful; long rigs and large trailers should go slowly and weigh whether to take it. Avoid towing in winter or snow. There is no posted vehicle-length ban, but large motorhomes find the Ouray switchbacks very tight.
