Golden aspens, crisp mountain air and a stop for something warm on the way home. A fall trip into Colorado’s mountains is hard to beat, and plenty of people have the same idea.
A little planning can help you spend more time enjoying the colors and less time behind the wheel. Whether you’re heading out for a hike, exploring a mountain town or making a weekend of it, here’s how to make the most of your leaf-peeping adventure along the I-70 Mountain Corridor.

Pick your travel time as carefully as your destination
Fall weekends can bring plenty of traffic to the I-70 Mountain Corridor. If your schedule allows, head up Tuesday through Thursday to see the fall colors. You’ll have a better chance of avoiding the weekend rush, with less competition for parking and space on the trails.
Traveling on a weekend? Make the GoI70 Travel Forecast your first stop when planning. Check the forecast for your travel dates instead of assuming last weekend’s timing will work again.
A few ways to give yourself more mountain time:
- Get an early start, ahead of the forecast’s busiest westbound I-70 hours.
- Plan your return, too. Consider staying for dinner and heading east after the peak travel window.
- Turn your day trip into an overnight stay. If your schedule allows, spend Sunday night in the mountains and return Monday.
- Keep your itinerary simple. Choose one area to explore instead of spending the day driving between crowded destinations.
Let someone else drive, and enjoy the view instead
Leaf peeping is better when everyone gets to look out the window. Bustang and Pegasus connect the Front Range with mountain communities along I-70, making a car-free fall outing an easy, low-cost option.
Bustang’s West Line travels I-70 between Denver and Grand Junction, with stops including Idaho Springs, Frisco, Vail and Avon. Board at Denver Union Station or the Denver Federal Center in Lakewood, depending on your location.
Pegasus offers a smaller shuttle van option between Denver and Avon, with stops including Idaho Springs, Frisco and Vail. Reserve your seat in advance.
Before buying tickets, check both your outbound and return options, confirm your boarding location and leave time for connections. These services share the highway with other travelers, so build some flexibility into your day.
Plan the last part of your trip
The key to a successful transit outing is knowing how you’ll get from the bus stop to your adventure.
Frisco is an easy starting point for exploring Summit County. From the Frisco Transit Center, use the free Summit Stage bus to reach destinations around the county. Vail also has free local buses, and Avon offers local transit connections. Find these systems through GoI70’s Mountain Transit guide.
For an easy fall outing, consider Vail: take Bustang or Pegasus to the Vail Transportation Center, explore the village, then enjoy a walk along Gore Creek. The Gore Creek Path offers a gentler way to take in fall scenery without committing to a strenuous mountain hike.
For any destination, check the walking distance, current local bus schedule and return connection before leaving home. Don’t assume every trailhead has transit service. Save your route and schedule to your phone so they’re available when you need them.
Driving? Fill the seats and have a parking backup
Meeting friends in the mountains? Why not meet closer to home and carpool together. Sharing a ride means fewer vehicles competing for road space and trailhead parking –and someone to split the driving and trip costs with.
Choose a primary destination and a backup before you leave. If the parking lot is full, move on to your alternate rather than circling or squeezing onto a roadside shoulder.
Popular viewing areas such as Guanella Pass have parking restrictions to preserve emergency access. Always follow posted signs and use designated parking areas. Check CDOT’s fall travel guidance before heading out.
Pack for fall, and the possibility of winter
A sunny afternoon in Denver doesn’t tell you what conditions will be like on a mountain pass. Bring warm layers, water, snacks and shoes suited to your plans. Check COtrip for current road conditions, closures and construction before departing and again before your return. You can check the status of fall colors at either OpenSnow or www.explorefall.com.
Fall snow is possible at higher elevations. Make sure your vehicle is ready for mountain conditions and review Colorado’s current traction requirements.
Once you arrive, stay on established trails, pack out your trash and give wildlife space. Let passengers handle photos while the vehicle is moving and stop only where it’s safe and legal.
The recipe for a great fall trip is simple: a flexible plan, a thoughtfully timed departure and plenty of time to enjoy wherever you land. Start with the GoI70 Travel Forecast, explore your transit options and get ready for more mountains, less traffic.
