Another hike we did kind of by accident. The parking lots were full so we had to park along Going to the Sun Road and walk back to the trailhead for Avalanche Lake trail. We took the Cedars trailhead because it was a shortcut to the Avalanche trail. The other option was a walk through a parking lot - this was MUCH better.
