“Travel is never a matter of money but of courage.” — Paulo Coelho (Author)
Most people misremember this drive. They remember the Rockies as a destination, a dramatic wall of mountains waiting somewhere beyond Denver. The reality is more interesting. Less than twenty minutes after leaving the city, the landscape begins to shift. The suburbs thin out, the road starts to climb, and the horizon transforms from skyline to summit.
By the time you reach the Eisenhower Tunnel (1.7-mile passage through the Continental Divide, 11,000+ feet above sea level), Denver feels very far away. The Rockies are not something you arrive at. They unfold gradually through every mile of road.
Colorado is certainly worth a road trip; the question is, which version of Colorado you want to experience.
KEY TAKEAWAYS
- The Rockies begin long before you reach the mountains; dramatic scenery starts shortly after Denver.
- I-70 offers Colorado’s most iconic road-trip experience, including the Eisenhower Tunnel, Vail, and Glenwood Canyon.
- US-285 offers fewer crowds and a slow experience across South Park, Buena Vista, and Salida.
- Combining both routes into a loop creates one of the most rewarding Colorado road-trip itineraries.
I-70: The Route Everyone Takes, For Good Reason
Interstate 70 west is the obvious choice, and it earns that status. The corridor runs from Denver through the foothills, past Georgetown’s intact Victorian storefronts and Beau Jo’s pizza in Idaho Springs, through the Eisenhower Tunnel, and down into ski country on the other side. Vail sits at mile 176. Beyond Vail, the road enters Glenwood Canyon. 18 miles of towering cliffs rising above the Colorado River and the interstate seem suspended between rock and water.
Glenwood Springs, at the western end, has hot springs that have been running since the 1880s, a walkable downtown, and enough accommodations to justify an overnight stop rather than a turnaround.
The catch is Friday afternoons in ski season. The trip from Denver to the tunnel takes about an hour on a Wednesday morning and closer to three on a Friday between November and March. If the plan includes a mountain weekend, leaving before noon or after 6:00 p.m. is not a suggestion. Ski parties traveling in a single Grech Lusso van avoid the coordination problem that two separate cars create on this stretch.
US-285: The Route That Takes Longer and Gives More
Heading south and west on US-285 feels like leaving Colorado’s tourist trail behind. The road climbs over Kenosha Pass and opens into South Park, a wide mountain valley that most visitors pass through on the way to somewhere else without realizing the valley is a destination.
Buena Vista is 123 miles from the city. The Collegiate Peaks sit directly to the west, a wall of fourteeners that provides one of the more unselfconscious mountain backdrops in the state. The Arkansas River runs through town and into Salida, 25 miles downstream, carrying some of the best whitewater in Colorado from May through August. Salida has an arts district along the river that punches well above its size, and neither town operates primarily as a resort. The restaurants exist for people who live there, which tends to produce better meals.
This road takes longer. It does not have Glenwood Canyon. What it has is a version of Colorado that the I-70 crowd does not usually reach.
FUN FACT
US 285 spans approximately 845.8 miles across Texas, New Mexico, and Colorado.
Planning the Trip
Travelers who want the best of both routes should view the trip as a loop rather than two separate drives. I-70 westbound into the mountains, an overnight in Glenwood Springs, then south to Salida and back to Denver on US-285 eastbound: four days, both covered, nothing repeated. Three days’ work if Buena Vista or Glenwood Springs is the endpoint rather than a midpoint.
Accommodation in these areas books out weeks in advance during the summer and ski season. The hot springs properties go first on weekends. Sorting out where to sleep before deciding when to leave avoids the situation where the dates are set, and nothing is available.
For groups sharing the drive, one larger vehicle is simpler on mountain roads. An RV dealer in Castle Rock, 30 miles south of Denver, carries purpose-built vans for this terrain.
What the Map Gets Wrong
Trusting the map too much is a common mistake for first-time visitors:
- Distances between mountain towns are longer than they appear. What reads as two hours can become three.
- Weather changes fast above 10,000 feet, sometimes within the same afternoon.
- Roads that look manageable in summer can require chains by late September.
All of it is manageable with a bit of preparation. Check road conditions the morning you leave.
Conclusion
The drive length doesn’t make a great Colorado road trip. It’s how much of the state you experience along the way. I-70 delivers iconic mountain scenery, dramatic canyons, and easy access to resort towns. US-285 offers a quieter, more authentic side of Colorado that many visitors never see. Whether you choose one route or combine both into a loop, the journey from Denver into the Rockies proves that in Colorado, the drive is often every bit as memorable as the destination.
FAQs
How long does a Denver to the Rockies drive take?
You can reach mountain areas along I-70 within an hour of Denver, though travel times can increase significantly during ski season and holiday weekends.
Which route is more scenic, I-70 or US-285?
Both are scenic, but they offer different experiences. I-70 features dramatic mountain passes and Glenwood Canyon, while US-285 provides quieter landscapes, small towns, and expansive valley views.
When is the best time for a Colorado road trip?
Late spring through early fall offers the most predictable driving conditions, while winter provides access to ski resorts but often brings heavier traffic and challenging weather.
Should I make Glenwood Springs an overnight stop?
Yes. The town’s hot springs, walkable downtown, and proximity to Glenwood Canyon make it one of the best overnight stops on a Colorado road trip.
