I'll be in Scotland next weekend at Crianlarich with some other sportive folks, but nobody who has done much hiking.

Assuming the weather is good, can any of you recommend a nearby hill we can walk up that has a path at least most of the way to the top?

Head towards Killin, small tiny tiny village then head towards Loch Tay and drive to Ben Lawyers, park at the visitors centre and walk up a mountain called Beinn Ghlas, you can go on to climb the second higher mountain if you wish called Ben Lawyers.

Beinn Ghlas has a path to the top, but take a map and compass to be on the safe side.
Killin is about 15 miles from Crainlarich.
