I stayed in Aviemore a couple of times last year. Don't bother with the Winking Owl "night club" it's dire.
Have a ride up to Inverness,over the Beauly Firth,over the Cromarty Firth,over the Dornoch Firth,hang a left to Bonar Bridge on the A949 then take the A837 across to Ledmore and down to Ullapool and back to Tore on the A835.
Hope the weather's fine for you. Gales when I was up there. Scared myself fartless going over all those Firths.
