Rattlesnake Gulch Loop

A moderately difficult trail leading 1.4 miles (one way) past spectacular views of the canyon and eastern plains to the remains of historic Crags hotel, 600 feet above the trailhead. Built in 1908, the hotel was accessed via an inclined railway from the canyon floor until it burned down in 1913. 

The trail continues as a .8 mile loop as it travels to a view of the Continental Divide and the railroad tracks, 1,200 feet above the trailhead. The trail is 1.4 miles to the ruins and another .8 mile for the loop, making the total roundtrip distance about 3.6 miles.
