Winter Ski Day Trips
Colorado's ski resorts make excellent day trips from Denver. Most require 2-3 hours of driving plus the traffic reality of I-70—leave before 6am or you'll sit in a parking lot. Return traffic is brutal; leave the slopes by 2pm or wait until 6pm.
Closest Options
- Loveland: 53 miles (90 min). Budget-friendly, no-frills skiing. First to open, last to close each season.
- Arapahoe Basin: 68 miles (90 min). High altitude (10,780 feet base), long season, expert terrain.
- Keystone: 75 miles (100 min). Night skiing, family-friendly, village atmosphere.
Worth the Extra Drive
- Breckenridge: 80 miles (120 min). Best town, great terrain variety, Peak 8 has bowls.
- Vail: 100 miles (130 min). World-class back bowls, expensive but incredible.
- Winter Park: 67 miles (90 min via US-40). Mary Jane side has legendary bumps. Avoid I-70 entirely.
Day Trip Tips
Traffic Reality
I-70 westbound backs up by 8am on summer weekends—sometimes at 6am during ski season. Leave Denver before sunrise for mountain destinations. Return traffic from the mountains starts around 3pm and can last until 8pm. Use Floyd Hill and Georgetown as traffic checkpoints—if they're backed up, find lunch or an activity to wait it out.
Altitude Matters
Denver sits at 5,280 feet. Many day trip destinations are 7,000-14,000 feet. Drink extra water, take it easy on hikes, and don't push through altitude sickness symptoms. Mount Evans summit (14,130 feet) affects almost everyone—short walks feel exhausting.
Weather Changes Fast
Mountain weather is unpredictable. Afternoon thunderstorms roll in regularly June-August. Morning fog or snow can close mountain passes any month. Check weather and road conditions before leaving. Bring layers even in summer—it's 20-40°F colder at elevation.
Gas Up Before Leaving
Mountain town gas stations charge $0.50-1.00 more per gallon than Denver. Fill up in the metro area. EV charging stations exist in most ski towns but can have waits during peak times.
Frequently Asked Questions
What's the best day trip from Denver for first-timers?
Boulder. It's close (45 min), has hiking and dining options for all levels, and captures Colorado's mountain-town atmosphere without requiring a full-day commitment. Red Rocks is shorter but more limited in activities.
Do I need a car for Denver day trips?
Yes, for most destinations. Some exceptions: Bustang buses run to Boulder, Fort Collins, and ski resorts. Tours go to Rocky Mountain National Park and ski areas. But having your own car gives you flexibility and usually costs less for groups.
How do I avoid I-70 traffic?
Leave before 6am westbound. Return before 2pm or after 6pm. US-40 to Winter Park bypasses I-70 entirely. US-285 south accesses different destinations. Weekdays have much lighter traffic than weekends.
What's the best day trip for hiking?
Rocky Mountain National Park has the most variety—from easy lakeside strolls to challenging peak climbs. Boulder's Chautauqua Park is closer and excellent. Mount Evans lets you hike at 14,000 feet after driving most of the way up.
Can I visit Rocky Mountain National Park without a reservation?
Before 5am or after 6pm, yes. During peak hours (9am-3pm) May-October, you need a timed entry permit. Book 30 days ahead at recreation.gov. They release some same-day permits at 5pm the day before, but they go fast.
