Would be a pity turning up at Inverness looking for ''Craigh na Dun'', at least for the filming location which is 80 miles back south & particulary if you haven''t your own transport. Pitlochry would be a good stop off, on the A9 & the Central Highland line.
There''s no public transport past the site, although the local bus to Kinloch Rannoch passes within a mile you will still be on the wrong side of the River Tummel and there is no crossing before the bridge at Kinloch Rannoch, 3.5 miles away, where the bus goes.
Its a 3.75 mile walk from Kinloch Rannoch, which you might do (& back again) between buses.*
3 hours might be pushing it but the 4 hrs between the 8:55 from Pitlochry & 13:50 from KR would leave some time for relaxing, or make a day of it. Perhaps even complete the 14 miles from Rannoch over the Schiehallion road to Tummel Bridge (where you can pick up the Bus again till after 7 pm.) Or you could try Dial-a-bike
No one outside Movieland will have heard of ''Craigh na Dun''. It''s Tulloch Croisk you''re looking for. Its a lovely journey to the spot & all around & its worth going a little further up the road to at least the Limestone Pavement, for which youll need a bit longer, but there are no standing stones.
* - No busses between those at 9:50 & 19:15 on a Tue & Thu though & none at all Sunday.
