Brian Metzler, in a special to the Rocky Mountain News, covers several former rail routes within an easy drive from Denver and the Front Range. Rollins Pass, the Switzerland Trail, and the Alpine Tunnel earn top honors. The Alpine Tunnel may dissapoint some, as the entrance has caved in. Still, efforts are underway to restore several historic structures in what would surely be the highest railroad museum in the country, if completed.
Greeley Tribune writer Tom Adams also gives a trip report of his venture up to Rollins Pass. This is a great trip from either side and you can certainly appreciate the views and avoiding the summer heat in Denver. Approaching the pass from the west side, however, gives one the chance to explore Rifle Sight Notch, a place where the rails looped over themselves by use of a trestle over a tunnel.
If you want to get up to the mountains for the day or even the weekend, there are few things better than exploring some Colorado Railroad history.
