Edinburgh has best castle in the UK in my never to humble opinion.

Inverness is a very cool town and nearby to some very cool sights; Loch Ness, Urquhart castle, Culoden, the town of Dornoch and a few others

The drive from Fort William to the ferry at the south end of the Isle of Skye is beautiful, the Isle of Skye is fantastic

The Orkney Islands are fantastic if you have an interest in history from neolithic times onward. A company called Westtrak? Westtrek? on the Isle of Westray in the Orkneys is a great way to spend a day. My youngest son and I did a day of fishing in the Orknies which was a great deal fun. There are standing stones in Orkney not as large as Stonehenge but you can park and walk right up the ones in Orkney.

Distillery tours are a must.

Driving outside of the large cities is not that bad, it takes some time to get used to and you can never relax whilst behind the wheel.

Enjoy the trip. GRF
