Parking for the west segment is in Eckerman. In Sault Ste. Marie park at the eastern terminus on Foss Street.
Not sure what the last poster couldn't see. I pulled up the map of the trail and got directions from our location in Brimley (Bay Mills Casino) to closest trail parking.
Unless you purchase maps it does not even allow you to see the maps even when you are online. This app is a waste of time unless you plan on spending money to get even the most basic info about trail.
