Winter Park Express (train)
The Winter Park Express has run from Denver Union Station to a stop next to Winter Park Resort on select dates, typically weekends. It's a scenic ride through the Moffat Tunnel and avoids I-70 driving altogether. Seats have sold out on popular dates. Check Winter Park's Getting Here page and Amtrak for current operations.
Snowstang (CDOT bus)
CDOT's Snowstang has offered seasonal weekend service from Denver-area stops to I-70 ski areas such as Loveland, Arapahoe Basin and Copper Mountain in past seasons. Routes and resorts can change. Check ridebustang.com.
RTD to Eldora
RTD has operated bus service from Boulder to Eldora during ski season, which can be combined with regional service from Denver to Boulder. Check rtd-denver.com for current routes.
Bustang and local buses to Summit County and Vail
CDOT's year-round Bustang West Line has stopped in Summit County (Frisco) and Vail in past seasons. From Frisco, free Summit Stage buses have connected to Breckenridge, Keystone and Copper. This works best for overnight trips with luggage-light packing. Verify each leg.
Private shuttles from DEN
Private shuttle companies run between Denver International Airport and mountain towns. They're often the easiest option for visitors flying in, particularly for Breckenridge, Keystone and Vail. Compare official operator websites and cancellation policies; we don't currently recommend a specific company.
Tips for car-free days
- Book seats in advance where reservations are offered.
- Pack light: boots in a bag, skis in a sleeve, layers you can carry.
- Know the last departure time and leave buffer.
- Consider renting gear at the resort to avoid carrying skis.
