In this episode, the Forestry Commission's recreation team is tasked with rebuilding steps on a well-worn pathway at Fairy Knowe, but the steps are up a 330-foot hill. Getting hunks of granite rock to the remote hill is one problem and digging them in by hand is another. A team of specialist contractors from Wales arrive in Galloway Forest to harvest timber from the most inaccessible areas using a massive system of cables and winches called the skyline. Deep in the forest, conservationists Bill and Christine breed and hand rear hyacinth macaws, the world's largest flying parrot. And on a remote peatbog the size of 32 football pitches, Graeme Little operates his own customised mulching machine.
