At the end of Local Hero a helicopter is seen flying over a loch taking Mac back to Houston. This was filmed at Loch Eilt near Lochailort in Morar.
The A830 runs close alongside Loch Eilt for most of the length of the loch. The filming location was at the western end of the loch around a mile before Arieniskill next to a long straight section of the road. At this point the road moves away from the loch side.
