About Us

Welcome to Of Rock and Chalk -York Region’s Premier Climbing Gym!

  Indoor rock climbing is fun for the whole family. Please come and join us any day of the week for a fun, exciting challenge! 

We do not have any age restrictions!

Come climb our walls!

  We offer over 46 routes, with heights varying from 10 to 37 feet.  We have six different bouldering areas, as well as simulated rock faces, chimney climbing, crack climbing, top rope and lead climbing areas.

  Our gym also has 10 auto belay systems allowing climbers to come in on their own and participate on our high walls.  The auto belay takes up the slack as the climber ascends and safely controls the descent when the climber lets go or falls. To learn more about this system check out TRUBLUE
