The Loch Ness Monster, or Nessie, is reported around Loch Ness in the Scottish Highlands, from the River Ness and Foyers to Urquhart Castle.
The route follows the legend from Saint Columba's water beast in AD 565 through the sightings of 1888 and 1933, the 1934 "surgeon's photograph" later shown to be a hoax, and the 1977 photo taken beside Urquhart Castle. The stories are claims and legends, not proven facts.
Harry Potter and the Prisoner of Azkaban was filmed on Lambeth Bridge and Stoney Street in London, the Glenfinnan Viaduct and Glen Coe in Scotland, Virginia Water in Surrey and the Divinity School in Oxford.
The third film was the first to use real locations extensively, so this route follows the story in film order, from the Knight Bus in London to the Dementors on the Highland train and the hospital wing in Oxford. Several lakes stood in for the Black Lake, so some pins are approximate.
Outlander's Scotland: the standing stones of Craigh na Dun near Kinloch Rannoch, Doune as Castle Leoch, Culross as Cranesmuir and Culloden moor. Claire, a twentieth-century nurse, touches a stone and wakes in 1743; a highlander knocks out the officer chasing her, and she marries Jamie Fraser to stay out of his reach.
They start near Kinloch Rannoch, where the production found its Craigh na Dun, then move to the real castles and villages playing Castle Leoch, Fort William, Cranesmuir and Lallybroch, and to a Fife castle standing in for a French abbey. The last stop is Culloden, the moor where Claire and Jamie say goodbye in the second-season finale.
One caveat: the standing stones on screen are a built set. The Bronze Age Clava Cairns near Inverness that fans often visit are said to have inspired them, but they are not where the circle was filmed.
