Rock Climbing

Pinnacles offers myriad climbing routes that vary from top rope to multi-pitch. The rock is composed of volcanic breccia, which is weaker than granite. Climbing can be dangerous due to brittle rock. Be sure to test bolts and holds before blindly trusting their strength as many are old or damaged. Start off on an easier route than you'd usually take, and prepare for a climb that will take longer than anticipated. Falling rock is also a concern - wear a helmet and don't climb above established trails where debris could injure hikers below. If climbing between January and July, take heed of advisories and avoid sensitive areas. A park ranger can provide you with detailed information.
