Our Mission

The Ontario Alliance of Climbers is an independent provincial, volunteer non-profit organization that works diligently to keep climbing and bouldering areas open.

The Bolt Fund is Live!

The OAC Bolt Replacement Fund assists route developers with the costs associated with replacing aged or worn out fixed hardware. Bolts and anchors may show wear, rust or damage after prolonged use and exposure. Replacing this gear is vital to improve climber safety and accessibility.

The Beaver Valley Climbing Festival is the perfect opportunity to learn some new skills!  Did you book a spot in one of the many clinics being offered by @ontherocksclimbing ?  You could learn anything from anchor building and introductory outdoor climbing skills, to multi pitch transitioning and self rescue. They're even offering a toprope session if you want to get on something more challenging but don't know how to get out there yourself!

Clinics are offered at a discount for #bvcf2025 ticket holders.  Get yours now at the 🔗 Link in our bio!

Devil’s Glen is just the beginning. Amendment ERO 019-8238 lays the groundwork for partnerships with Ontario Parks that could open the door to more climbing opportunities across the province. A collaborative path forward starts here—with climbers supporting conservation while advocating for responsible access.

When you comment on this amendment, you’re not just protecting access at DG. You’re helping create a model that could support climbing at other provincial parks in the future. Let’s build this future together.

And soon you'll be able to show your support with fancy new stickers!  We'll be launching these at the Beaver Valley Climbing Festival this weekend -- but you have to show proof that you've left a comment in order to get one ❤️ Can't make it to the festival?  Find an OAC representative afterwards!

Congratulations, climbers! The Ontario Ministry of Environment, Conservation and Parks (MECP) has heard your voices. Thanks to your letters and advocacy, they are proposing an amendment to the Devil’s Glen Provincial Park Management Plan that would formally recognize rock climbing at DG.

This is a massive milestone and a direct result of our collective action. You did this. Let’s celebrate — but more importantly, let’s finish the job.

The proposed amendment is open for public comment. Supportive comments are a vital part of the approval process. We need every climber to act now.
