Shetland: Scotland's Wondrous Isles

With 1700 miles of coastline, Shetland loves a race in a yoal: a traditional boat with links to the Vikings. We meet a skipper preparing for the last race of the season.

Viking outfits and a replica galley ship are among requirements for Scalloway's annual fire festival celebrating Shetlanders' heritage. Plus, a pod of orcas are spotted.

Lifelong crofter Pearl Young prepares for the harvest festival, and we visit Shetland's first commercial oyster farm and the islands' only wildlife sanctuary.

Exploring this archipelago of wonders, including the famous ponies, the thrilling landscape, and some of the residents, from long-timers to recent arrivals who don't want to leave.
