From the highest paved road in North America to a canyon with no guardrails and walls that drop 800 metres — this isn’t a shortcut. It’s the whole point. At a glance Total scenic distance~390 miles (628 km) over 2 days Direct drive (no stops)215 miles (346 km) · ~4.5 hrs Best season: Late May through early October Overnight stop: Buena Vista or Gunnison. Key roads: I-70, CO-103, CO-5, US-285, US-24, US-50, US-550. Highest point: Mount Blue Sky summit: 14,130 ft (4,304 m).
The direct drive from Denver to Ouray takes just over four hours and follows US-50 west through the flat sagebrush scrub of Montrose. It gets the job done. This route is not that drive.
What follows instead is a two-day loop through the geological heart of Colorado — a route that climbs higher than any paved road in North America, drops into a canyon so sheer that the walls block the sun by mid-afternoon, and ends on a stretch of highway notorious enough to have a name derived, depending on who you ask, from its construction cost, its gold-laden gravel, or the fact that locals swore they wouldn’t drive it for anything less than a million dollars.
The route covers roughly 390 miles (628 km). It demands patience, a full tank before every mountain pass, and an honest reckoning with the fact that the Million Dollar Highway has almost no guardrails. If that sounds like a reasonable trade for some of the most dramatic driving in the American West, read on.
Route overview
The route follows the MyScenicDrives itinerary for Denver to Ouray, condensed into two days. Day 1 is front-loaded with altitude — the first morning pushes you onto the highest paved road in North America before noon. Day 2 follows river valleys west before climbing onto US-550 for the final approach into Ouray.

Day 1 Denver into the alpine — the climb to 14,000 feet
~185 miles (298 km) · Allow 7–9 hours including stops · Overnight in Buena Vista
Departure point
Denver
Leave Denver early — ideally by 7 a.m. The high country plays by its own schedule, and afternoon thunderstorms build fast above 11,000 feet. The further up you want to go, the earlier you need to be there. Fill your tank before you leave the city; fuel stations above 9,000 feet are scarce and expensive when you do find them.
Take I-70 westbound. The city thins out quickly and the mountains don’t wait — within 20 minutes the foothills are already stacking up ahead of you.
Stop 1 · 14 miles (23 km) from Denver · 20 min
Lariat Loop Scenic & Historic Byway
40-mile (64 km) loop · Golden, Morrison & Evergreen foothills
Exit I-70 at Exit 259 toward Golden and pick up the Lariat Loop, a 40-mile (64 km) National Scenic Byway that connects the foothill communities of Golden, Morrison, and Evergreen. The road climbs through ponderosa pine and open meadow, with the kind of rocky switchbacks that feel like a warm-up for what comes later.
Don’t miss Red Rocks Amphitheatre — the natural sandstone formations here are worth stopping for even when there’s no concert on. The acoustics that make it famous are incidental to the geology, which dates back 300 million years. The road also passes through Morrison, where you can follow a short detour to Dinosaur Ridge, a site where actual fossilised footprints are visible in the roadside rock face.
Allow 2–3 hours if you want to walk any trails. If you’re holding time for the byway ahead, an hour is enough to catch the Red Rocks overlook and continue east toward Idaho Springs on I-70.
Stop 2 · 23 miles (37 km) from Lariat Loop · 25 min drive to byway start
Mount Blue Sky Scenic Byway (formerly Mount Evans)
28 miles (45 km) · Summit: 14,130 ft (4,304 m) · Highest paved road in North America
Reopening Memorial Day 2026: The Mount Blue Sky highway (CO-5 from Echo Lake to the summit) was closed for road reconstruction throughout 2025 and is scheduled to reopen the Friday before Memorial Day 2026 — subject to weather. Reservations and a fee are now required to access the summit section. Book in advance at recreation.gov. The lower section of CO-103 from Idaho Springs to Echo Lake remains open.
Take Exit 240 off I-70 at Idaho Springs and head south on CO-103 toward Echo Lake. The byway starts here and climbs 28 miles (45 km) to a summit at 14,130 feet (4,304 m) — the highest point accessible by paved road in North America, beating Pikes Peak Highway by a narrow 25 feet (8 m).
The drive passes through five distinct climate zones. Below the treeline the road is flanked by Engelmann spruce and stands of Bristlecone pines up to 2,500 years old at the Mount Goliath Natural Area. Above Echo Lake — where the 1926 log-cabin lodge is worth a 15-minute stop — the trees disappear entirely and the alpine tundra opens out. Mountain goats graze the upper slopes, frequently within metres of the road.
At the summit, air pressure is about 40% lower than at sea level. The walk to the true peak is only a quarter of a mile (400 m) with 120 feet (37 m) of gain, but you’ll feel every step. Be off the mountain by noon — afternoon lightning storms develop fast and the summit is the highest point for a considerable distance in every direction.
Vehicles over 30 feet (9 m) are not permitted on CO-5. The road has no guardrails in the upper section and is shared with cyclists year-round where it’s open.
Practical notes
- Book timed entry tickets at recreation.gov — entry windows fill on summer weekends
- Fees: $3–$15 per vehicle depending on entry point; non-refundable $2 reservation fee applies
- Bring water and a warm layer — even in July, summit temperatures can drop below freezing in a storm
- The byway is seasonal: open Memorial Day through Labor Day to the summit, weather permitting

Guanella Pass Scenic Byway
22 miles (35 km) · Summit: 11,669 ft (3,557 m) · Georgetown to Grant
Backtrack briefly to I-70 and take Exit 228 into Georgetown — a well-preserved Victorian silver-mining town worth a 20-minute walk if you have it — then pick up the Guanella Pass road heading south. The byway runs 22 miles (35 km) over the Continental Divide at 11,669 feet (3,557 m) before dropping to the small community of Grant on US-285.
This is one of the more accessible high-altitude passes on the route — the road is paved end-to-end and passable in a standard 2WD vehicle. The summit sits above treeline with wide-open views of the surrounding peaks, and the descent through aspen groves on the south side runs golden in late September. In late summer, the area above treeline on the north side is one of the better places in Colorado to spot moose.
From Grant, pick up US-285 south toward Fairplay and onward to Buena Vista, where you’ll spend the night.
Overnight · ~75 miles (121 km) from Guanella Pass via US-285
Buena Vista, Colorado
Elevation: 7,965 ft (2,428 m) · Arkansas River Valley
Buena Vista sits at the northern edge of the Arkansas River Valley, flanked by the Collegiate Peaks — a cluster of fourteen-thousand-foot summits named after Harvard, Yale, Columbia, Princeton, and Oxford . It’s a small town with a genuine outdoor economy: raft guides, bike shops, a handful of decent restaurants, and enough accommodation to make a comfortable overnight stop without planning too far ahead outside peak season.
The Arkansas River runs directly through town and the stretch below Buena Vista is Colorado’s most popular commercial whitewater corridor — worth considering if you have extra time in the morning before Day 2.

Stop 4 · Starts in Buena Vista
Collegiate Peaks Scenic Byway
56 miles (90 km) · US-24 and CO-82 · Buena Vista to Poncha Springs
The Collegiate Peaks Scenic Byway runs 56 miles (90 km) along the base of the most densely clustered group of fourteeners in North America. On a clear morning the view west from US-24 is unambiguous: Mount Harvard (14,420 ft / 4,395 m) — the highest of the group and the third highest peak in Colorado — dominates the skyline, with Mount Columbia, Mount Yale, and Mount Princeton arranged in a wide arc to the south.
The town of Salida, midway along the byway, has a compact historic downtown and a good coffee stop before the longer stretch to Gunnison. It sits at the confluence of US-50 and US-285, which is the junction where you’ll turn west.
From Salida follow US-50 west — the road shadows the Arkansas River upstream before climbing through the Monarch Pass area and descending into the Gunnison Valley.
Stop 5 · ~90 miles (145 km) from Buena Vista via US-50 · ~1 hr 30 min
Gunnison and the Blue Mesa Reservoir
Blue Mesa: 20 miles (32 km) long · Colorado’s largest body of water
The Gunnison Valley opens out west of Salida into a wide basin ringed by sage-covered hills and red-rock mesas. Gunnison itself is a compact ranching and university town with reliable fuel and the last decent concentration of food options before Montrose. Worth a stop for lunch if your timing works out.
West of Gunnison, US-50 runs along the northern shore of Blue Mesa Reservoir, part of the Curecanti National Recreation Area. At 20 miles (32 km) in length, it’s the largest body of water in Colorado. The late-afternoon light on Blue Mesa — particularly in autumn, when the surrounding hills have turned gold — is worth more than a drive-by. There are several pull-offs along US-50 directly above the water.
Curecanti’s Elk Creek Visitor Center sits on the north shore and is worth 20 minutes for the geology displays alone, which explain how the series of dams on the Gunnison River created these three reservoirs — and what lay beneath the water before they were filled.

Black Canyon of the Gunnison National Park
South Rim Road: 6 miles (10 km) · Wall depth: up to 2,722 ft (830 m)
“No other canyon in North America combines the depth, narrowness, sheerness, and somber countenance of the Black Canyon.” — National Park Service
Turn north off US-50 onto CO-347 — the Black Canyon of the Gunnison National Park is 15 miles (24 km) up the road. The South Rim entry station charges $20 per vehicle; the South Rim Road then runs 6 miles (10 km) along the canyon edge, with 12 named overlooks.
The Gunnison River has been cutting this canyon for two million years. At its narrowest point — the Narrows — the canyon is only 40 feet (12 m) wide at the river, with walls rising 1,730 feet (527 m) on either side. The dark, crystalline schist and gneiss that make up those walls are among the oldest exposed rock in Colorado — some of it is nearly 1.8 billion years old.
Painted Wall Overlook is the one to prioritise: the vertical face here drops 2,250 feet (686 m) — taller than the Empire State Building — and is streaked with pale pink pegmatite intrusions that give it its name. Budget 60–90 minutes for the rim road.
Black Canyon essentials
- Entry: $20 per vehicle, or free with an America the Beautiful pass
- No food or fuel in the park — stock up in Gunnison before you turn off US-50
- The canyon is open year-round; the South Rim Road is paved and suitable for all vehicles
- Cell reception is unreliable in the park — download offline maps before you arrive

Montrose
Last fuel stop before Ouray
Montrose is where US-50 ends and US-550 begins. Fill up here — this is the last reliable fuel before Ouray, 35 miles (56 km) to the south, and there are no services on the road between them. The town has nothing in particular to recommend it over any other mid-size Colorado junction, but it does mark the start of the most famous stretch of road on this entire route.
Stop 8 · 35 miles (56 km) from Montrose · ~50 min
The Million Dollar Highway — US-550 south to Ouray
35 miles (56 km) Montrose to Ouray · Red Mountain Pass: 11,018 ft (3,358 m)
US-550 south from Montrose follows the Uncompahgre River through a progressively narrowing canyon before the walls close in completely and the road carves directly into the rock face. The mountains arrive all at once: one moment you’re in a wide open valley, the next you’re threading through cliffs that rise vertically on both sides, with a river gorge somewhere far below your right-hand window.
The 25 miles (40 km) from Ouray to Silverton constitute what is technically called the Million Dollar Highway — though most drivers approach the name only from the Ouray end. The origin of the name is disputed: it may refer to the reported million-dollar-per-mile construction cost in the 1920s, the gold ore allegedly mixed into the road’s fill gravel, or a piece of dry local humour about how much someone would need to be paid to drive it willingly. All three explanations are plausible.
Guardrails are largely absent from the steepest sections — not an oversight, but a practical necessity. Snowplows need room to push the winter accumulation over the side of the mountain.
The road crests at Red Mountain Pass at 11,018 feet (3,358 m). The three Red Mountain peaks to the east take their colour from iron oxide in the rock — the rust-red ridgelines against a clear sky are arresting, and there are pull-offs at the summit. The ruins of the Yankee Girl Mine are visible from the road on the descent toward Silverton.
If you’re arriving from Montrose rather than driving the full Silverton-to-Ouray stretch, you’ll approach Ouray from the north — the canyon walls tighten and then the road makes a dramatic series of switchbacks down into the box canyon where the town sits. At 7,792 feet (2,375 m), Ouray is ringed on three sides by peaks that reach well above 13,000 feet (3,962 m). The last switchback before the descent into town gives a view that, once seen, makes the entire two-day drive feel like a reasonable proposition.
Driving the Million Dollar Highway: This is a well-maintained, fully paved two-lane road — but its lack of guardrails and 8% grades demand full attention. Large RVs travel in both directions. If you are uncomfortable driving close to unprotected drop-offs, consider approaching Ouray from the north only (Montrose → Ouray) and leaving the Silverton section for another trip. The road is technically open year-round but can close for weather and avalanche mitigation between October and May.
Destination
Ouray — the Switzerland of America
Elevation: 7,792 ft (2,375 m) · Population: ~1,000
Ouray sits inside a nearly circular box canyon, its Victorian-era storefronts backed against walls that rise 2,000 feet (610 m) straight up. The town is small enough to walk end-to-end in 20 minutes and has been a destination since the hot springs were first developed in the 1920s — the Ouray Hot Springs Pool is still open and worth an evening soak after two days of driving.
Box Canyon Falls, a five-minute walk from the main street, channels the Canyon Creek through a slot so narrow you can touch both walls simultaneously, with a waterfall dropping 285 feet (87 m) into the gorge below. It costs $5 to enter and is one of those short walks that leaves a disproportionate impression.
In January, the Ouray Ice Park — a man-made ice climbing venue in the Uncompahgre Gorge — draws climbers from across the world. In summer, the same gorge runs with snowmelt and the town becomes a base for jeep trails, hot springs, and hiking into the surrounding San Juan peaks.
You earned dinner. The drive was the whole point.
Before you go — practical information
When to drive this route
The window is late May through early October. The Mount Blue Sky Byway (CO-5) is typically open only from Memorial Day to Labor Day. Guanella Pass closes to through traffic in winter, though the lower Georgetown end often remains passable. The Million Dollar Highway is technically open year-round but can close for avalanche mitigation at any time between October and May — check COTrip.org for current conditions before you leave Montrose.
Fuel
Fill up in Denver, again in Idaho Springs (before Mount Blue Sky), in Gunnison, and again in Montrose. There are no reliable fuel stops between Montrose and Ouray. Don’t test the gauge on the high passes.
Vehicle requirements
All roads on this route are paved and passable in a standard 2WD vehicle in dry summer conditions. Mount Blue Sky prohibits vehicles over 30 feet (9 m) on CO-5. Large RVs should exercise caution — and significant patience — on the Million Dollar Highway.
Altitude awareness
This route spends most of two days above 8,000 feet (2,438 m), with a summit that touches 14,130 feet (4,304 m). Headaches, nausea, and fatigue are common symptoms of acute mountain sickness at this elevation, especially if you’re arriving from sea level. Drink water consistently, avoid alcohol on the first night, and descend if symptoms worsen.
