I may not be the ultimate climbing gym reviewer having only been to less than ten different gyms, but Hardrock Nunawading, in my view, is a decent gym. It doesn't quite compare to Camp 5 in Malaysia, where I've spent the largest amount of my indoor climbing time, but then again pitching the two may not be entirely fair.
Camp 5 is located in a city mall and is not representative of your average work-out hole. In fact, Malaysian climbers in Kuala Lumpur may not realise the luxury they have in the form of fresh, clean carpets, aromatherapic bathrooms and state-of-the-art holds, quite often fresh off the block.
Hardrock in my books, has all its boxes ticked – there are plenty of routes (nice and high), a café, bouldering area and lower routes for kids. The routes are nicely set and sometimes reminiscent of the outdoors.
Although the area is small (by my standards) they manage to pack a lot of routes onto one wall, which may or may not be a good thing – but I like to see it as an efficient use of space. I would have liked to see more slab climbs with tiny crimpy holds but I'm not sure if they have those kind of holds here.
Bouldering You won't be able to do much traversing as the bouldering space is small but the routes are interesting and there are some serious overhangs and roofs for the hard core.
Hardrock is very kid friendly and packed with kids on the weekend. Instructors seem friendly and experienced in taking the young monkeys around. Children can climb from as young as four. They also do birthday parties, which I think is a good idea for the older kids.
