This walk takes you from Glasgow to Fort Williams, crossing the country through the Highlands along the largest loch in Scotland, covering 153 miles of trails. The terrain is not too taxing, but it can be very slippery when it rains. It gets difficult if you try to cover too much in each day, but you can always try a more leisurely pace. You will have to walk on the road from time to time, but not all the way. There are many hotels and inns along the way, but it's also possible to camp by the side of the loch or in the forest.
