“Would strongly recommend for anybody to come and try it out. The team is really great and helpful and it's always nice to meet new people. The gym is really nice too!”
“Don’t go during the weekend, more like a kids playground than a boulder gym. Routes not adapted for intermediate level climbers. Big surface but not a lot of routes”
