The Amtrak Winter Park Express ski train, which runs from Denver to Winter Park Resort and neighboring Fraser, kicked off its 2025/2026 ski season on December 19th, providing a traffic-free way to access the mountains without getting on Interstate 70. While train currently only operates on Thursdays, Fridays, Saturdays, and Sundays (aside from major holidays), there's a chance the train could run 7 days a week in future years.
