Crag features

The Blob Rock Area has some of the finest climbing in Boulder Canyon. Located on the sunny north side of the canyon, it's a great place to climb in cooler weather. There is something for all climbers: multi-pitch trad climbs, runout face climbs, and modern sport routes.

Many of the older routes are a bit runout; they were established at a time when bolting wasn't a popular option for dealing with scary climbing. Most of the modern routes, however, have bolts where necessary to protect difficult moves.

The area is composed of several formations: the main rocks are Blob Rock and East Blob; two smaller rocks are Little Blob and Small Package Block.

Approach notes

Park in a small pullout on the right, just past Cob Rock. This is about 6.7 miles up the canyon.

A trail begins from the right side of the pullout. Follow it as it zig-zags up the hill. It will take you to the base of the Main Wall of Blob Rock in about 10 or 15 minutes.

Access Advice

This area is often closed for raptor nesting from February 1 through July 31. However, in 2006 the climbing ban was lifted early, and the area was reopened to climbing in early March. Signs are posted at the trailhead informing climbers of the current status of the raptor closure.
