Zap straight over to Inverness and start from there. Drop down to loch spey and follow the river North to its estuary near the place where Baxters produce it's superb Cullen skink. You do of course have to pop into every distillery on the way and Grantown will lose you your license just by breathing the air.
Drop into the Baxters factory, have some "proper" Cullen skink, served in the visitor centre restaurant, with crusty bread and Mr Baxter's portrait glowering down on you. Then follow the coast round to where
@AlisonF lives, Aberdeen, but not before visiting Ellon church and putting some flowers on Tom Patey's grave for me. Over night at the gorgeous "aire" at port Errol Harbour.
Drop into the granite city, buy
@AlisonF a big glass of wine for me because I think she is lovely, then keep to the coast, being in Ullapool you would have seen enough of hills and stags in Wester Ross. Before leaving Aberdeen pop into the Gordon Highlanders museum.
Keep to the coast, drop down to Crail, spend some time there, a fascinating place, then avoiding Kirkaldy drop over the bridge into Edinburgh.
Everyone thinks hills and mountains with the highlands, the coast can be interesting. When you get to Cullen, do a detour, go left instead of right to the Findhorn estuary. A totally beautiful place of isolated beaches that stretch for miles and the saltmarsh with it's bird colonies. Magic!
Oh, and don't overnight at Lossiemouth. I spent a lovely night there parked up on the beach by a beachfront bar and just next door the noisy neighbours kept revving up their Typhoons. It was like trying to sleep in a hair dryer.
