Denver to Aspen in winter

The shortest summer route is closed all winter. What the drive actually looks like from November to May, how long it takes, and what can change it on the day.

In summer, the quickest way from Denver to Aspen is over Independence Pass. In winter that road is closed, so every drive from Denver goes the long way: west on I-70 over the Divide and through Glenwood Canyon, then back up the Roaring Fork Valley on Highway 82. Plan for four hours in good conditions, and more on a snowy Friday.

Flying into Denver is often cheaper and more reliable than flying into Aspen. Whether it's the right choice depends on the day, the weather and who is driving. This is how we think about it.

IThe Route

How the winter drive works

Route
I-70 west to Glenwood Springs, then Highway 82 up the valley to Aspen.About 220 miles from Denver International Airport.
Drive time
About four hours door to door on a clear weekday.Add an hour or more on snow days and at weekend peaks through the mountain corridor.
High points
The Eisenhower–Johnson tunnels and Vail Pass, both above 10,000 feet.These are where weather and traffic most often slow the drive.
Independence Pass
Closed for the winter, normally from early November to late May.In 2025 it closed on November 17; in 2026 it reopened on May 21.
IIWhat Can Change on the Day

Three things to check before you leave

The traction law

From September 1 to May 31, Colorado's traction law applies on I-70 between Morrison and Dotsero. Tyres need at least 3/16-inch tread, and four-wheel or all-wheel drive is no longer enough on its own: the tyres must be winter, all-weather or mud-and-snow rated, or the car must carry chains or an approved traction device. Many rental cars don't meet it.

Glenwood Canyon

CDOT closes I-70 through the canyon for safety when there is a risk of rockfall or debris. If a closure is expected to last more than an hour, the recommended detour runs north on CO 9, US 40 and CO 13, adding about two and a half hours. CDOT asks drivers not to use Cottonwood Pass or other county and forest roads as shortcuts.

Timing

Westbound traffic builds on Friday afternoons and Saturday mornings; eastbound on Sunday afternoons. Leaving Denver before noon on a weekday is usually the easiest drive of the week.

IIIWhen It Makes Sense

Denver versus flying closer

Denver has the most flights, the most direct routes and usually the lowest fares. Flights into Aspen are shorter to the door but more exposed to weather, and in a storm they can be cancelled or land in Grand Junction or Eagle instead.

For families with luggage and ski gear, a Denver arrival works best with a driver who does the mountain corridor every week, rather than a rental car after a long flight. For a Friday arrival in heavy snow, flying into Eagle or Aspen and accepting some risk of delay is often less tiring than four to six hours on I-70.

Arriving at altitude matters too: Aspen sits near 8,000 feet, and a long drive at the end of a travel day makes the first evening harder. Your first evening in Aspen.

Worth knowing

If a snowy day is forecast, decide the night before

Check COtrip.org or call 511 for closures and chain-law status. If Vail Pass or the canyon is closing, it is usually better to stay in Denver and drive first thing than to spend the evening in traffic.

Planning for someone else

Assistants, advisors and concierge teams

Send the flight and where your clients are staying. We arrange a driver who knows the corridor, watch the road and the canyon on the day, and have the residence ready when they arrive. Send the details.

Common questions

How long is the drive from Denver to Aspen in winter?

About four hours from Denver International Airport in good conditions, via I-70 and Glenwood Springs. Allow five or more on snow days or at weekend peaks.

Is Independence Pass open in winter?

No. Highway 82 over Independence Pass normally closes in early November and reopens in late May. In winter the route from Denver goes through Glenwood Springs.

Do I need snow tyres to drive to Aspen?

From September 1 to May 31, Colorado's traction law applies on I-70 between Morrison and Dotsero. Tyres need at least 3/16-inch tread and, even on four-wheel or all-wheel drive, must be rated winter, all-weather or mud-and-snow, or you must carry chains or an approved traction device.

What happens if Glenwood Canyon closes?

CDOT's recommended alternate route for longer closures uses CO 9, US 40 and CO 13, adding about two and a half hours. Cottonwood Pass and other back roads are not recommended as detours.

Should we fly into Denver or Aspen?

Denver usually has more flights and lower fares but a long drive; Aspen is minutes from town but more exposed to winter weather. Eagle sits in between, about 90 minutes away.
