Know Before You Go
From the east: Driving south out of Nederland on Colorado 119, turn west at Rollinsville on Rollins Pass Road. The trailhead starts at the gate 16 miles from Rollinsville. The trestles can be accessed by a short hike over Needle's Eye to the old railbed. The distance to the trestles from the gate is about 3/4 of a mile. From the west: Drive 10 miles from Winter Park Ski Area on Rollins Pass Road (also called Corona Pass Road) to the top of Rollins Pass. The trestles are about a mile from the old Corona station site.
Both sides of Rollins Pass are barely accessible by sedan. Higher clearance vehicles are better although 4wd is not necessary. Both sides can also be accessed by mountain bike. The ride is not difficult but it is at high altitude, which can make the ride more challenging. Be sure to note the views from the trestles of the King Lake area of the Indian Peaks Wilderness. There are few views of Colorado that are prettier. Crossing snow at the top of the pass is always a possibility even in late summer. Care is warranted when crossing snowfields. Finally, the standard rules for outdoor Colorado activities apply. The trestles are above timberline and dangerous storms move in quickly. Go early and get down early to avoid lightning.
