The Southesk Lake Loop, a remote and rugged backcountry trail within Jasper National Park, is characterized by steep elevations, potentially hazardous river crossings, and unpredictable weather. Hazards include swift river currents, wildlife encounters, and navigating through wildfire-affected areas. Tentative bed down sites are limited to established backcountry campsites, which should be used to minimize environmental impact and for safety reasons. Key features include the scenic Southesk River suspension bridge and the challenging terrain of Cairn Pass. Due to the trail’s complexity and potential risks, thorough preparation and backcountry experience are essential.
