Countryfile: Season 28, Episode 33

28 - 33: Lochaber

2016 is the 60th anniversary of the Duke of Edinburgh Awards scheme, and to mark the occasion Countryfile heads to the wilds of the west Highlands of Scotland. Matt joins the intrepid team mid-way through their five-day Diamond Challenge. They have already scaled Ben Nevis, and when Matt meets them they are canoeing the Great Glen all the way to Inverness. Matt also meets the scientist who has made it her mission to fight the menace of Scotland's infamous midges. Sean meets mountaineer Hamish Macinnes, whose inventions, including his famous stretcher, have saved hundreds of lives.

Naomi explores Glencoe's 'Atlantic woodland' - a rich and rare habitat, where she gets a close look at the amazingly intricate lichens and mosses that carpet the woodland. Helen is in the Peak District with a party of schoolchildren undertaking their bronze Duke of Edinburgh, and she walks a stretch of Kinder Scout with HRH Prince Edward, himself a Gold Award holder and trustee of the scheme.

And as the red grouse shooting season gets underway, Charlotte Smith meets the supporters and critics of one of Britain's most controversial country pursuits.
