Quick Info
Distance: 67 miles. Drive time: 90 minutes (good conditions). Route: I-70 W to US-40 over Berthoud Pass. Key challenge: Berthoud Pass in winter conditions.
Winter Park is the closest major ski resort to Denver - just 67 miles and about 90 minutes in good conditions. The drive avoids the notorious I-70 traffic to Summit County resorts by routing over Berthoud Pass instead. But that mountain pass requires respect in winter conditions.
The Route
From Denver:
- Take I-70 West from Denver
- Exit at US-40 (Exit 232, Empire/Granby)
- Follow US-40 over Berthoud Pass
- Continue to Winter Park Resort
Total distance is about 67 miles. Without traffic or weather delays, expect 90 minutes. The route leaves I-70 before the Eisenhower Tunnel, avoiding much of the Summit County traffic.
Berthoud Pass
Berthoud Pass (11,307 feet) is the crux of the drive. This mountain pass requires attention in winter:
What to expect:
- Steep grades (6-7%) on both sides
- Sharp switchback turns
- Potential for snow, ice, and wind
- Limited visibility in storms
- Avalanche terrain (road occasionally closes)
Winter driving requirements:
- Colorado traction law applies - AWD/4WD or chains required in winter conditions
- Good winter tires essential
- Confidence with mountain driving
In good conditions, Berthoud Pass is straightforward. In storms, it demands careful driving. Check conditions before departure.
Timing Your Drive
To avoid traffic:
- Leave Denver by 6:30am on weekends
- Weekdays have less traffic
- I-70 section can still backup on peak mornings
Return traffic:
- Leave by 2pm to beat the worst return traffic
- Or stay late (after 6pm) and let traffic clear
- Sunday afternoons are worst
Winter Park's US-40 route typically has less return traffic than I-70 corridor resorts, but the I-70 section from Empire to Denver still backs up.
Checking Conditions
Before you leave:
- CDOT website for road conditions and closures
- COTrip.org for real-time traffic and cameras
- Weather forecast for Berthoud Pass specifically
Berthoud Pass can be closed for avalanche control or extreme weather when I-70 is open. Always check pass conditions specifically.
Alternative: The Ski Train
Don't want to drive? The Winter Park Express ski train runs weekends from Denver Union Station. No driving, no parking, no pass to navigate. It's more expensive but eliminates all road concerns.
Tips
Fuel up in Denver: Gas is cheaper in the city than in the mountains.
Bring supplies: Chains (if not AWD), snacks, water, phone charger. Mountain roads can have delays.
Drive to conditions: If visibility is poor or roads are icy, slow down. Arriving late is better than not arriving.
Know your vehicle: If you're uncomfortable with mountain driving or have an unsuitable vehicle, consider the train or shuttle alternatives.
Frequently Asked Questions
Do I need 4WD?
Recommended but not always required. Colorado traction law mandates adequate traction in winter conditions - AWD/4WD or chains on 2WD vehicles.
Is Berthoud Pass scary?
It requires attention but isn't extreme. In clear conditions, it's a scenic mountain drive. In storms, it demands careful driving.
How does traffic compare to I-70?
Generally better. The US-40 route avoids Eisenhower Tunnel backups. Return traffic still impacts the I-70 section to Denver.
Can I use a rental car?
Check rental agreement for mountain driving restrictions. An AWD rental is recommended for winter visits.
