(MODERATE to DIFFICULT) This adventure travels on some of the most scenic sections of Jasper National Park’s North Boundary Trail. Starting on the northeast corner of the Park at Rock Lake, we follow the course of the Snake Indian River, before turning up the Blue Creek valley. The Upper Blue Creek valley is home to the Ancient Wall, and Natural Arch, two legendary geological features. Our route makes a scenic loop travelling over McLaren’s Pass to reach Little Heaven, before returning to Rock Lake. Travel on this portion of the North Boundary Trail is generally good, though there can be muddy sections and several unbridged creek crossings.
