Cruise Loch Ness Fancy trying to get a gander at the Loch Ness Monster? There's only one way and that is on a boat trip out onto the deep and foreboding waters of Loch Ness. "Nessie" has certainly defied many a scientific attempt at location. The earliest mention of the serpentine beast with a snakelike head dates back to Adomnán's account of the life of St. Columba, completed in the late 7th century. Cruises leave from just south of Inverness and feature interpretive guides who can tell much more than monster stories.
