Drive to the top of the canyon and you will be climbing on the lovely granite around Brighton, surrounded by aspen trees and alpine lakes. Keep driving up and over Guardsman Pass and make the hike to the Gman Boulders for a serene bouldering experience on highly unique rock. While LCC may have BCC beat for roadside classics, Big is perfect for those who love to explore and get away from the crowds. ETHICS No gluing, chipping, or manufacturing any holds. Generally just respect the places you get to climb at. Clean up after yourself, pick up any trash you find, brush your ticks and excess chalk off the holds, clean your climbing shoes before pulling on the wall. Stick to established trails the best you can. Respect the watershed protections, there is no swimming allowed in Lower Big Cottonwood and Brighton. HISTORY Big Cottonwood has a long history of sport/trad climbing, but the first recorded bouldering was likely done in the 80's and 90's. The canyon is covered in A Bouldering Guide to Utah by Baldwin, Beck, and Russo, and features many of the quartzite boulders lower in the canyon, as well as mention of the Milly Boulder in Brighton and a few surrounding lines. The rest of Brighton and Guardsman areas were a bit more recently explored, largely developed by Jay Keener, Victor Copeland, Tommy Rigby, Alec and Larson Quick, and others. The lower canyon has recently seen a surge of development, with boulders like Nightman, Forged in Fire, and the Ramp Wall being put up in the last few years. There is a lot of rock up here, and there is still plenty of development to be done, especially if you're willing to hike. From I-215, take the 6200 S exit and head east, following signs to Big Cottonwood/Brighton. Once in the canyon follow directions on KAYA for parking to different areas. Guardsman Pass is also easily accessed from Park City.
