Secret Scotland with Susan Calman

The comedian ventures to the islands of Mull and Staffa, nestled along the west coast of Scotland and home to some of the most breathtaking sights the country has to offer. Beginning her trip in Staffa, Susan visits the cathedral-like cavern of Fingal's Cave, one of the UK's true natural wonders formed over thousands of years. Her need for speed is fulfilled when she witnesses the Mull Rally, while in Tobermory, she visits a biscuit factory run on sustainable energy. Lastly, the presenter goes in search of the largest bird of prey in the UK - the white-tailed sea eagle.

The comedian ventures off the mainland to the Isle of Bute for a privileged look at what is said to be Scotland's first million-pound home - Mount Stuart House. In Argyll, Susan visits Kilmartin Glen, an ancient valley and home to the Scotti people who gave Scotland its name. She visits a Bronze Age tomb and learns how to make a copper axe in the way they were made thousands of years ago. Then, on the shores of Loch Fyne, she discovers the secrets of oyster cultivation before looking for beavers in the beautiful Knapdale Forest.

The isles of Lewis and Harris form Britain's largest offshore island, with a rich history dating back thousands of years. Susan seeks out the home of the world-famous Harris Tweed, visiting a local weaver where she tries her hand at making some of the fabric. Then in Habost, she learns how to Step Dance - a centuries old practice that was almost lost from Scotland for ever. At Callanish, Susan visits some awe-inspiring Neolithic giants - 49 standing stones, predating Stonehenge and steeped in mystery. Nearby, she learns the secret to jewellery making that captures the texture of these ancient standing stones.
