Shetland: Scotland's Wondrous Isles

The journey begins on the tiny island of Noss, with wardens Jen and Sally. They are the only residents and live a truly off-grid existence – with no mains water, electricity or gas – and they even grow their own food in case they become stranded by the unpredictable weather. The upside is they have a front row seat to witness some of Shetland's most spectacular wildlife.

In this episode, lifelong crofter Pearl Young takes the spotlight. She's living off the land in the most traditional way possible but it's not a solitary existence. With help from husband Willie, she's getting ready for the highlight of her year – the annual harvest festival in the church she and Willie were married.

Shetlanders are proud of their Viking history and heritage. None more so than when it comes to the annual fire festivals that kick start each year.

The biggest sheep sale of the year takes place in Lerwick, where farmer Eric has the honour of judging the pre-sale show to crown the best ram of the day. All over the islands teams race yoal boats - a traditional Shetland vessel with links to its Viking past, and skipper Laura and her team from the Hamnavoe club prepare for the last and crucial race of the season at their home regatta.

On the second largest island in Shetland, Yell, locals gear up for their annual show - a celebration of all things agricultural and horticultural as well as local heritage. Third generation farmer James and his family have been involved in the show since it started so he's keen to put on a good show - but his cattle are less keen to take part. Veg grower John hopes to win the battle of the heavyweights with his huge pumpkin. And we follow Eve, the last remaining professional Fair Isle chair maker.
