Description

Begin along the flat, lower, two-way section of Side Door west of a tailings overlook. Climb to Prospect Hill Road just west of the top of Side Door. At the midway point, Screen Door can be used to cross to the midpoint (and larger features) of Side Door.

Back Door is a nice climb; not too flat and not too steep. The Town of Breckenridge has designated this "climbing recommended", and with its completion, the upper section of Side Door is designated downhill only.
