Bouldering 101

Our Bouldering 101 course is designed to cover the fundamentals of good climbing technique and terminology.  You’ll get lots of time practicing movement on the wall with one of our instructors. This course is geared towards people who have climbed fewer than 5 times including those who have never climbed before.

The 2 hour program is a great way to get into the sport of bouldering. You will be in a group of 5 and our coach will help introduce you to the sport.

The $40+tax includes rental shoes but the charge DOES NOT include your admission for the day (so you will need to have a daypass, punch card, or membership).

Spaces are limited, if we are at capacity please call us to be added to a wait list.
This program is for beginners to the sport. Participants must be 16+.


Hi and welcome to boulder 101! My name is Josué Kurke and I will be your coach for bouldering 101. I have been climbing for almost 4 years and last year I drove across the U.S. and Canada for a 6 week long climbing road trip. I have a degree in math from the University of Waterloo and have been climbing at GRR since 2020. I am passionate about teaching and currently am also the assistant head coach for the Rubble Rebels program.

Hello my name is Scotty Inglis. I am now a climbing coach at GRR! I have been climbing for 15+ years and have traveled all across North America for climbing. I have experience in all forms of rock climbing but am passionately dedicated to bouldering. Professionally, I’m a full-time climbing arborist for a local Tree care company. GRR has been my home since it first opened and I am excited to share my stoke.

Ready to get started?

Saturday, March 23 @ 10:30AM – 12:30PM at Kitchener with Coach Scotty
