The A837 skirting Loch Assynt is a varied road ranging from narrow single-track to a wide, flowing single carriageway near Lochinver. Sights to see along the 50 mile stretch are Suilven and Canisp, later on you have Calda House and of course Ardvreck Castle. This is one the finest stretches of roads in Scotland, up and down with fast corners and great views. To do this in a road trip I would probably base myself at Inverness, Its about a two hour journey up to the north east of Scotland. Once you’ve had your stop offs for pics and to take in the sights I would suggest you carry on to Durness, there are campsites and a couple of hostels but you would have to book early if staying overnight, alternatively stay the night in Ullapool which has many more places to stay.
