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

Need to know!


Climbers under the age of 14 must be supervised at all times by another person who is at least 16 years of age. Supervision must be direct and involved and climbers must remain in the same room as their supervisor at all times. It is recommended that you bring additional supervisors for groups larger than 4 as you will not be able to climb in other rooms without a supervisor.

Exceptions are made for members of our youth team, youth who have taken a beginner’s course or on a case-by –case basis with the manager’s discretion. Exceptions can be revoked at any time due to lack of respect for the facility rules.  



Save time by filling out your waiver online before you come in!

Anyone going in to the climbing area (even just to watch!) will need a waiver form filled out.  

  • Waivers for minors must be filled out by the parent/legal guardian so if you will be coming with minors that are not yours please get their parent/legal guardian to fill out waiver form before.
  • Anyone with an incomplete waiver that cannot be completed by their parent/guardian will not be able to enter the climbing area.
