Must say my only experience with this route was from west to east on my bike and stayed overnight in Fort Augustus. What about a copy of the 'official guide' to the Way I sure that will give all the information and places to stay etc. We used to have a copy here, but as it is, when you try to lay your hands on something like this, hmm...who has my copy etc.
Don't think that there would be a problem going from E-W. I guess that most of the linear routes are set up do in both directions. The route Rangers have an office in Fort Augustus....source of information?
