Dougie is in the centre of Scotland to climb Schiehallion, one of the country's most distinctive and popular munroes. He hears how landowners the John Muir Trust are balancing the needs of the 30,000 visitors a year with protecting this unique upland habitat.

Further up the mountain, he meets a member of the Tayside Mountain Rescue Team to find out why call-outs increase at this time of year. Meanwhile, Cammy is near Blairgowrie to find out why a fruit famer is giving away his blueberry crop to charity, and Arlene is in Perthshire to uncover the story of the Maharaja who made Scotland his home. Elsewhere, landscape photographer Shahbaz Majeed is just outside Perth, on the final section of his journey along the course of the River Tay.

Dougie is in the far north west of Sutherland at Kinlochbervie to listen out for one of the sounds of the autumn - the deer roaring as the stags battle it out in the annual rut.

Arlene is near Moffat, where she learns about the eco alternatives to plastic tree tubes, while Cammy is in Fife to meet a farmer who has planted apple trees in the middle of his fields and to find out what the benefits are to the land and wildlife. Meanwhile, Rosie discovers the joys of mudlarking - digging up treasure that was once somebody's rubbish.
