The 46-mile A830 road from Fort William to Mallaig is traditionally known as the Road to the Isles, as it leads to the jumping-off point for ferries to the Small Isles and Skye, itself a stepping stone to the Outer Hebrides. This is a region steeped in Jacobite history, having witnessed both the beginning and the end of Bonnie Prince Charlie's doomed attempt to regain the British throne in 1745–46.
The final section of this scenic route, between Arisaig and Mallaig, has been upgraded to a fast straight road. Unless you're in a hurry, opt instead for the more scenic old road (signposted Alternative Coastal Route).
Between the A830 and the A87 far to the north lie Knoydart and Glenelg – Scotland's 'Empty Quarter'.
