John Cobb held the world land speed record three times. On 29 September 1952 he was killed on Loch Ness while trying for the water speed record in Crusader, a jet-powered boat. The people of Glenurquhart put up a memorial cairn beside the A82 south of Urquhart Castle, looking out over the stretch of water where it happened.
It's a brief stop, with a lay-by and one of the better open views down the loch.
