Time Out says
It's hard to miss Hardrock's CBD location. Located above Swanston Street, this climbing venue offers floor-to-ceiling views of the street and its multiple intersections. For keen climbers, Hardrock offer 44 top rope walls, which are up to 16 metres high. The venue also has four auto-belay walls, so you don’t have to bring a spotter as the automated cable system will catch climbers if they fall. For experienced climbers, the venue's grade ranges from six to 30, so if you have one, bring your locking karabiner and they can provide the climbing shoes. The climbs are for punters 11 years and over, while younger climbers can engage in interactive rock climbing games. Hardrock also has a venue in Nunawading which also features a bouldering cave and 51 top rope walls up to 14 metres high.
