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 @accyyz will also be at the Beaver Valley Climbing Festival, setting up top ropes for those who may need a partner or some extra confidence getting outside! 

Toprope set ups are a great way to meet new friends and get a taste of some real rock.  It's always a party on the ACC ropes!  You can find your new climbing partner here, or tackle those fears of getting out on your own. 

Toprope waiting lines can be avoided by signing up for a clinic with either of our guiding groups, @muskokamountainworks or @ontherocksclimbing !  But if you're in for more of a social day, the ACC topropes might be exactly what you're looking for!
