Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
Overview: Short technical canyon that's easily visible on the northside of Canyon Lake across from the Acadia picnic area. Park & blow up your packraft, paddle across and find the approach west & north around the western ridge of the canyon. Scramble up and over the saddle and into the lower canyon where you'll soon find pleanty of boulder, rock hopping and bushwhacking. There's also a few short rappels thru the narrows with the final one being 70ft into a 'room' formed by a massive boulder of course. =p It's a half mile of hiking but don't forget the 1.5 miles of padling to & from it...
