The trail is an out-and-back, but may be done as a loop if you prefer to ride the old 1A road out or back. Once you arrive at Ross Lake, head up the trail for about 50 metres to the junction. Turn right and follow this trail out to the 1A. Do not go left; bikes are not allowed beyond this point. Once on the 1A head right (east) back to Lake Louise Drive.
If you’re not riding from town up the tramline trail (#2), then the best spot to park is just past the St. Piran road, which is the first right turn immediately after Deer Lodge hotel, in the public carpark. Don’t park on St. Piran as this is private property.
