North of Lake Lousie off the Icefields Parkway, the Alexandra River Trail is a rough and tumble hike on abandoned roads leading to a spectacular, remote wilderness valley (21km / 90m). There are several challenging river crossings best done during low water seasons. Be ready for a little bushwacking. To reach the trailhead from Lake Louise, follow TC 1 west to SR93 north. The trailhead is located off SR93 about 15km north of Saskatchewan Crossing.
Overall, Alexandra River is the 5th most popular hiking trail of all 11 hikes in Alberta.
