Many things can threaten our access.

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.

As the climbing season starts to wind down, we'd like to take a moment to recognize crags where climbing is not only tolerated but celebrated! We'd also like to share some important reminders about climber responsibility and proper processes and procedures when climbing at @conservationhalton (CH) Parks (Mount Nemo, Kelso & Rattlesnake).

Most importantly, please remember that the addition of any permanent climbing hardware, creation of new routes, or modification of existing routes (or altering of/tampering with existing hardware) is strictly prohibited without the express written consent of CH. Should you have recommendations on routes or hardware installation, please contact the Ontario Alliance of Climbers (OAC) so that we can contact our partners at CH and discuss potential changes. Existing worn-out hardware which poses a safety risk may either be replaced or maintained, but new bolting on managed land requires land manager permission. You can report bad bolts online(🔗 in our bio), and we will ensure that this information reaches the appropriate people.

We address this matter following the discovery of recently added hardware that were installed without proper permissions. These actions can lead to the creation of unmanageable and possibly unsafe routes that could be detrimental to the environment and our climbing community.

CH is a valued partner to the climbing community and one of our best models for relationships with land managers. CH openly supports rock climbing at some of their parks -- including many crags you're familiar with such as Mount Nemo, Kelso, Rattlesnake Point, Bottle Glass and Buffalo Crag.

As good ambassadors for the outdoors, please climb responsibly and respect the land and its managers. CH works hard to protect these spaces for everyone's enjoyment. Climbers can help by staying on established trails and climbing routes, minimizing their impact. CH staff are responsible for trail maintenance and site care. If you see a fallen tree or other vegetation hazard, please let us know so that we can request that it be addressed.

Thank you for helping protect access, preserve the environment, and keep our community safe!

The Crags Calendar helps us raise awareness and funds in support of Ontario access.  Please consider donating a photo!
