The final leg of Chris Packham and Megan McCubbin's journey takes them to the Western Isles, in the far north of Scotland. On the Isle of Harris, the pair are delighted to see white-tailed eagles almost as soon as they leave the car park, before spotting several golden eagles up in the hills. A stop in Bragar on the Isle of Lewis allows them to marvel at the Whale Bone Arch - a garden gate fashioned from the jaw bones of a blue whale which washed up on a nearby beach over a hundred years ago. Later, they head out on a boat from Stornoway Harbour and are treated to a display by a pod of Risso's dolphins
