We're staying near Fort William again this year (Roy Bridge in fact), this year we're there for a whole week and looking at things to do with our 5 year old.
He's a big fan of the Gondola's on Aanoch Mor (apologies if I've spelt it wrong).
One thing we were considering is going for a ride on the train, last year we went to Malaig, this year we thought we'd try Rannoch Moor.
Obviously with a 5 year old we won't be going wandering on the moors, but is worth going for a train ride to enjoy the scenery? Also which station would be the best to go to, Rannoch station I would imagine has little there, so it would be Bridge Of Orchy or Tyndrum, I think there would be too little time ar Crianlarich before making the return journey
