Overview
From the top of Bummers Rock
“Bummers Rock” is a scenic little outcrop jutting southward toward the Boulder Creek drainage. It serves up anything from an easy family stroll through the woods to YDS 5.12 climbing. Nice views of the hills surrounding Boulder are available from the open, rocky summit, reached by an easy (Class 2+) scramble. This summit combines nicely as part of a day-outing to nearby peaks including Sugarloaf Peak or would be a nice place in and of its self to take small kids or out-of-state visitors.
