Cycling sisters Kerry and Kirsty MacPhee from South Uist take to social media to find out the nation's favourite cycle routes. In this episode, they are in north east Skye in the Trotternish peninsula with local Kerr Gibb, who is lucky enough to count this route as his commute to work. Starting at Portree harbour they cycle past some of Skye's most famous landmarks. They admire the strange rock formations of the Old Man of Storr and Kilt Rock before tackling the steep climb up the winding road to the Quiraing. The girls also hear about Skye's reputation as the Jurassic Isle and visit the dinosaur footprints on Staffin beach which have made the island so famous in recent years.
