Tempting.
Length: 54.4km
Time: 5-8 Hours
Book: Mountain Biking in the Canadian Rockies – Doug Eastcott
Effort: Medium
Rating: 9/10
Technicality: ModerateThis ride is out and back on 100% singletrack. It goes right along the shore of Lake Minnewanka, and it’s awesome fast, rolling, techincal (in places), rideable singletrack. Just don’t get too excited and knock a hiker off a cliff. Park at the North side of the Lake Minnewanka dam. Mountain bikes ARE allowed on this trail, so don’t take stick from the hikers.
