From the mile-high city of Denver to the “Switzerland of America” in the San Juan Mountains, a Colorado road trip is one of the great drives in the United States, all soaring peaks, alpine towns, hot springs and national parks. We drove the full loop ourselves, so this is our first-hand Colorado road trip itinerary, with a route map, flexible 5, 7 and 10-day options, and honest picks for every stop.
Key Takeaways
- The classic loop runs from Denver through Boulder, Glenwood Springs, the San Juan Mountains (Ouray), Mesa Verde and the Great Sand Dunes, and back via Buena Vista and Colorado Springs.
- Give it 7 to 10 days for the full loop; a 5-day version covers Denver, the Rockies and a couple of highlights.
- The Million Dollar Highway to Ouray and the surreal Great Sand Dunes are the scenic showstoppers.
- Late spring to early autumn (June–September) is best, once the high mountain passes are open and snow-free.
- You need a car (a regular one is fine for the main route in summer); this is a self-drive by definition.

This Colorado road trip loops out of Denver, so it works whether you fly in or drive. Below is the route map, then flexible day-count options, then a stop-by-stop guide with everything we loved along the way.
The Route Map
Here’s the full loop mapped out, the highlighted line runs Denver → Boulder → Glenwood Springs → Grand Junction → Ouray → Mesa Verde → Great Sand Dunes → Buena Vista → Colorado Springs → back to Denver. Shorten it by trimming the southern stops for a 5-day version.
Colorado Road Trip Itinerary Options (5, 7 & 10 Days)
The beauty of this loop is that it flexes to your trip length. Here’s how we’d shape it for 5, 7 or 10 days.
| Trip length | Route | Best for |
|---|---|---|
| 5 days | Denver → Boulder → Glenwood Springs → Buena Vista → Colorado Springs | The Rockies + Front Range highlights |
| 7 days | Add Ouray & the Million Dollar Highway (the San Juans) | The classic loop with the scenic showstopper |
| 10 days | Add Mesa Verde & the Great Sand Dunes | The full loop, two national parks, unhurried |
The 5-day version
Short on time? Base around Denver and the central Rockies: a day or two in Denver and Boulder, over to Glenwood Springs for the hot springs and Hanging Lake, then loop back via Buena Vista and Colorado Springs. It skips the far southwest but still delivers the mountains, hot springs and Garden of the Gods.
The 7 to 10-day version
With a week or more, add the dramatic southwest: drive the Million Dollar Highway to Ouray, then continue to Mesa Verde’s cliff dwellings and the Great Sand Dunes before looping back north. Ten days lets you do it all without rushing. That’s how we’d do it, given the choice.
The Best Stops on the Loop
Here’s every stop on the loop at a glance, followed by a full writeup of each.
| Stop | Days | Highlights |

Denver
Most Colorado road trips start in Denver, the mile-high capital, and it’s worth a day or two before you head for the hills. Explore the LoDo (Lower Downtown) district, the craft-beer scene (Colorado practically invented it), the museums and the buzzy food halls. On the way out of town, stop at Lookout Mountain for your first big Rockies view and Buffalo Bill’s grave. It’s the perfect place to pick up your rental car or RV and stock up. If you have an extra day, Rocky Mountain National Park is an easy add-on north of Denver, with the highest paved road in the country (Trail Ridge Road) and superb alpine hiking, a worthy detour before you commit to the western loop.
Boulder
Just 45 minutes from Denver, Boulder is a laid-back university town beneath the dramatic Flatirons rock formations. Wander the pedestrianised Pearl Street Mall (buskers, boutiques and cafes), hike or bike in the foothills, and soak up one of the healthiest, happiest towns in America. It’s an easy, enjoyable first stop before the mountains proper.
Glenwood Springs
Two to three hours west, Glenwood Springs is one of our favourite stops, home to the world’s largest hot-springs pool and the atmospheric Iron Mountain Hot Springs overlooking the Colorado River. Nearby, the famous Hanging Lake trail leads to a surreal turquoise lake fed by waterfalls (reservations required), and Rifle Falls is a lush triple waterfall worth the short detour. It’s the perfect blend of adventure and relaxation.
A word on Hanging Lake: it’s one of Colorado’s most beautiful and most protected spots, so a permit and shuttle reservation are required in the warmer months, book ahead. The steep 1.2-mile climb is worth every step for the impossibly clear turquoise water and the travertine falls at the top. If you only soak in one hot spring on the whole trip, make it Iron Mountain, where dozens of small pools step down toward the river with the mountains all around.
Grand Junction and Colorado Wine Country
Continue west to Grand Junction, the gateway to Colorado’s surprising wine country (the Grand Valley around Palisade) and the red-rock canyons of the Colorado National Monument, a mini Grand Canyon with a dramatic scenic drive. It’s a change of scenery from the alpine north, all desert mesas and vineyards, and a good overnight before you turn south into the San Juans.
Ouray and the Million Dollar Highway
This is the scenic climax of the trip. The drive south to Ouray on the Million Dollar Highway (US-550) is one of the most jaw-dropping mountain roads in America, hairpin switchbacks, sheer drops and endless San Juan peaks. Tiny Ouray itself, nicknamed the “Switzerland of America”, sits in a natural amphitheatre of mountains, with hot springs, waterfalls and a gorgeous historic main street. Give it a night or two; it was a highlight for us.
Drive the Million Dollar Highway slowly and in daylight, as there are few guardrails and plenty of reasons to stop for photos. Once in Ouray, don’t miss the Ouray Hot Springs, the box-canyon waterfall walk right from town, and the Perimeter Trail for a big view down over the rooftops. If you have an extra day, the neighbouring towns of Silverton and Telluride make gorgeous side trips deeper into the San Juans.
Mesa Verde National Park
In the far southwest, Mesa Verde National Park protects the extraordinary cliff dwellings of the Ancestral Puebloan people, stone villages built into the canyon walls over 700 years ago. Take a ranger-guided tour into Cliff Palace or Balcony House for a genuinely moving glimpse into ancient life. It’s unlike anywhere else on the route and well worth the detour southwest.
Great Sand Dunes National Park
Heading back east, one of Colorado’s most surreal sights awaits: the Great Sand Dunes, North America’s tallest sand dunes, rising up to 750 feet against a backdrop of snow-capped peaks. Sandboard or sled down the dunes, splash in the seasonal Medano Creek at their base, and stay for the incredible dark-sky stargazing. It feels like the Sahara dropped into the Rockies.
Time your visit for the shoulders of the day: the sand gets blazing hot at midday in summer, so sunrise or late afternoon is best for climbing the dunes (and for the light). Bring a sandboard or sled (rent one nearby), plenty of water, and stay after dark, this is a certified International Dark Sky Park, and the Milky Way over the dunes is a sight we still talk about.
Buena Vista
Back in the central mountains, Buena Vista sits beneath the Collegiate Peaks and is a hub for whitewater rafting on the Arkansas River, more hot springs, and hiking. It’s a relaxed, outdoorsy town to slow down in before the final leg, and a great spot to soak tired legs after all that driving.
Colorado Springs
The last major stop is Colorado Springs, home to the free and unmissable Garden of the Gods, a park of towering red-rock formations against the peaks, plus Pikes Peak (drive or take the cog railway to 14,000 feet) and Helen Hunt Falls. From here it’s a short drive back to Denver to close the loop.
A Colorado road trip is a self-drive by definition, and having your own vehicle is the only way to reach the hot springs, national parks and mountain passes on this route at your own pace.
We use and recommend Discover Cars to compare rental rates across suppliers, so you can pick up in Denver and drive the full loop; a regular car is fine for the main route in summer.
How Long Do You Need?
A week is the sweet spot for this loop, enough for Denver, the central Rockies, Ouray and one or two of the southern parks. Ten days lets you drive the entire loop, including both Mesa Verde and the Great Sand Dunes, at a relaxed pace with time to hike and soak. Five days works if you focus on Denver, Boulder, Glenwood Springs and the Front Range. Whatever the length, don’t over-pack the schedule, the drives (and the views) are half the point, so build in time to pull over. For the packing side, our road trip checklist covers what to bring.
Best Time to Go
The best time for a Colorado road trip is late spring to early autumn, roughly June to September, when the high mountain passes (including the Million Dollar Highway) are open and snow-free, and hiking and rafting are at their best. Plan for right after Memorial Day weekend for fewer crowds with good conditions. September brings golden aspens and thinner crowds, a beautiful time to go. Winter closes some high routes and is really for skiing rather than a scenic loop. For the gear that makes any US road trip smoother, our road trip accessories list covers it, and there’s a full breakdown in our cost of a two-week USA road trip.
