Episode list

Paul Murton explores the wilds of Loch Etive, from the spectacular tidal race of the Falls of Lora, where kayakers revel in the overfalls and ride a three-metre standing wave, to high-altitude camping on a hill opposite Buchaille Etive More, watching the sunset, and lights up the hundreds of lochans across Rannoch Moor.

Paul travels from Loch Gairloch to Loch Maree, a grand tour that includes meeting the king and queen of Islonia, matching a medieval feat of archery, diving on a wartime wreck in Loch Ewe and finding himself short-changed at the money tree on an island in Loch Maree.

Paul begins his Grand Tour with a chilly swim across Loch Ba high on Rannoch Moor, struggles against the elements while train-spotting and meets some veteran Tunnel Tigers - men who tunnelled deep inside the Grampians, diverting water to hydroelectric schemes.

Paul travels into the secret heart of the Rough Bounds of Knoydart by way of Loch nan Umbh, Loch Morar, Loch Nevis and Loch Arkaig. He lifts the lid on the area's secret connection with the celebrated SOE (Special Operations Executive) which Churchill hoped would set Europe ablaze. On the shores of several lochs, agents were trained in the dark arts of sabotage. On Loch Morar, Paul meets a man who claims to have seen the legendary monster Morag (pronounced Voorag), before getting a ferry to Inverie in the heart of the Rough Bounds and searching for Jacobite gold beside Loch Arkaig.

1.2 billion years ago, the far north of Sutherland was struck by a meteorite. The wreckage of this cataclysmic event has been almost completely worn away by time, but the rocks in the landscape still bear some traces, which Paul unpicks as he embarks on a grand tour from Lairg on Loch Shin to Lochinver and, finally, to the summit of Suilven - the sugarloaf mountain.

Paul explores some lochs close to Scotland's densely populated central belt. Starting on the banks of the most famous lake in Scotland - the Lake of Menteith - Paul wanders through an enchanting landscape, visiting Loch Ard, Loch Arklet, Loch Katrine and Loch Achray, before climbing a mountain in miniature, Ben Venue.
