Fort Augustus at the southern end of Loch Ness strides the Caledonian Canal, linking several lochs and forming a passage between the Atlantic and the North Seas. Watching the locks in action is itself an interesting occupation. But beware, the town becomes a bottleneck in summer as traffic negotiates its swing bridge. Don't miss Fort Augustus Abbey on Loch Ness, given to the Benedictines in 1867. The abbey church is modern.
