Grand Tours of Scotland's Lochs (2017)

S1E3 Taming the Wild

Paul Murton kicks off his Grand Tour with a brisk swim in the frigid waters of Loch Ba, located on Rannoch Moor. He faces challenging weather conditions while indulging in his passion for trainspotting and encounters a group of seasoned Tunnel Tigers—men who worked tirelessly tunneling through the Grampians to redirect water for hydroelectric projects.
