So this year, we’re doing something a little different. We will be one of many host locations for Camp Out for Cancer. It’s a fundraiser that raises money to send kids with cancer to camp. The Camp Trillium fundraiser will take place on October 14th, 2017. At GRR we encourage our members, their friends and family to take part and join our team. Participants will raise money and on Oct. 14th we will Camp Out at GRR. There will be movies, games, headlamp climbing, food, and a sleepover inside the gym! This is an event for all ages! So get some friends together and register at!

Come out for a climb this Sunday between 11am-3pm and support Mom2Mom Africa! Volunteers from the Waterloo Professional Firefighters Association will be here to belay for you! So get off the auto-belays and try some top-rope! GRR will be donating 100% of profits made from daypasses to help build a school in Arusha, Tanzania

Climb for Cancer – This Sunday!

This Sunday is Climb for Cancer at GRR!  This means that from 1-5pm our teams will be climbing to beat cancer!  This also means that during that time, the easier top-rope climbs (5.4-5.7) will be occupied by our teams.   However, they won’t be on the auto-belays or boulders.  We are still open to the public.
