Hello everyone, I'm back and we had a brilliant time. Thanks everyone for your suggestions. We're working on the pics and the write up this week.
@crackle, we didn't take the A82 up loch ness, we took the rather more, er, undulating B852 instead. My knees nearly exploded! We also had to sack Ulva because of a severe weather warning. A force 7 was blowing there, so we hung out in tobermoray instead.
@pottsy, Colonsay was fab apart from the midges which were the worst I have ever experienced.
@rual I wished we'd known about the tracks across rannoch moor - a friend of ours attempted to cross it the other year and strongly advised us not to. We'll have to do the other tracks you mentioned on a later trip.
