The Crack is a stunning, steep sided crevasse slicing through a quartzite rock cliff, located in Killarney Provincial Park. The destination is popular with hikers for the iconic Killarney views of pristine lakes framed by the white quartzite La Cloche mountains. Trail access on Highway 637 allows day hikers a short, but rugged hike to the top of the ridge.

This route makes a large loop through the southern Santa Catalina mountains, by taking Arizona Trail passage 11 and Arizona Trail alternate passage 11E to create a 40+ mile loop with over 12K+ feet of elevation gain & loss.
