Car
As in all areas of rural Scotland, a car is a great asset for exploring the Great Glen, especially because the best of the area is away from the main roads. You can use the main A82 from Inverness to Fort William, or use the smaller B862/B852 roads to explore the much quieter east side of Loch Ness. Mallaig, west of Fort William, is reached via a new road, but there are still a few narrow and winding single-lane roads, which require slower speeds and greater concentration.
In the Great Glen, the best sights are often hidden from the main road, which is an excellent reason to favor peaceful rural byways and to avoid as much as possible the busy A96 and A9, which carry much of the traffic in the area.
