We walked the WHW right at the start of the season several years ago. Very busy and all b&b's booked out that week as everyone seemed to be on the same schedule, probably available more if starting a day later.I found the route unchallenging, a stroll really. There was a lot of 'track' walking which was quite boring in places, saved only by the scenery.I did finish it with a walk from Kinlochleven, hiding some gear in the forest in Glen Nevis, then up and down the Ben, before meeting up with my companion (He didn't want to do the Ben) and walking into Fort William.Many people who enjoyed the WHW,say they were disappointed with the Great Glen Way extention.
