Caledonian Canal - Spean Bridge

The road from Fort William to Inverness (A82) offers a splendid panorama of the Caledonian fault. The stretch as far as Spean Bridge affords many superb views of the northern side of Ben Nevis. More feats of engineering were required when water from Loch Treig was diverted to generate electricity. Spean Bridge makes an excellent base for walks through the Glen Roy nature reserve. "Parallel Roads", as the terraces which run along the slope are called, indicate the various levels reached by the water of a Pleistocene lake which was dammed up by Ice Age glaciers.
