Short version- take the train to Crianlarich if pressed for time.
Saturday: rain, all the time. The trail was fine to Inversnaid, where I stayed in the hostel (which had good food).
Sunday: more carrying than I’d expected from Inversnaid to the bothy by Doune. (When people say “it’s not rideable”, I still usually assume that I can ride it haha). As I was running behind schedule I took the A82 for the gradual climb from Inverarnan to Crianlarich (silly mistake!). It started hailing around Bridge of Orchy :/
Mon: some folks persuaded me it would be more fun to finish the WHW and play in the trails around Glen Nevis. The weather was great. I took the train round to Corrour.
Hope I can come back in the summer!
