FYI - there is a new trail as you leave Banff Park, called the High Rockies Trail. I have ridden it a couple of times now and the first part out to Buller Pass is complete. Here is the link to the map and information. http://kananaskisblog.com/high-rockies-trail/2015/ The first part from Goat Creek to Three Sisters Dam (approx 10km) is on reclaimed logging roads with some boardwalk sections. The section from Three Sisters Dam to Buller Pass Parking is about 15km - all single track and super fun. That's as far as the trail goes for now and this pops you back on the Spray Lakes road about 2km north of the road into Shark mtn Road. Currently, the TD route uses the Shark Mtn Road to connect back on the Spray Lakes Road.
