Once again, Australians and Aussie climbers in particular prove themselves to be amongst some of the biggest nutters on the planet. In this video from Brad Schimanski, the playfully named 'Stunt Monkey' sets out to climb at Narrowneck in the Blue Mountains. As if climbing in a monkey costume weren't crazy enough, 'Stunt Monkey' attempts the route 'Wonderland' free solo. The climb is graded 20 in Australian money which weighs in at about French 6b. Not the hardest route in the world, but when you can't see your comically oversized felt feet through your monkey helmet, we doubt it's going to feel easy!
