Somewhat wooded but also plenty of warm sun. Excellent, though coarse granite boulders with a variety of sloping and crimpy holds. Callouses are a big help! See the Prescott Area Bouldering Guide for the most recent information.

Getting There 

From 307 hiking trail cut left (westish) off the trail when a close grouping of large boulders can be seen just off the trail at a slow right hand curve.


From school bus pullout on Senator Highway, hike up the obvious trail across the street until it deadends at an obvious group of largish boudlers.

This is the beautiful line of knobs on Bolt Rock right of the arete. Committing, high-steppy moves up the slabby face lead to a high crux and a scary, less-than-positive topout. The arete is off for the V3, using it drops the grade to around V1 but the problem is almost as fun....[more]   Browse More Classics in AZ

Went up to Groom Creek for the first time last week and fell in love. So many fun problems and it was great seeing a strong (and friendly!) local scene. With MP being what it is, it's not always easy finding your way around, especially by yourself... so I've snapped a few pictures and started adding a few references to the Marty Karabin topo to help anyone that's unfamiliar have an easier day.
If I got anything wrong or mixed up, let me know!
