Niall Iain Macdonald and Calum Macaulay take to the water as they explore the Crinan Canal. Niall Iain begins his journey in Tarbert, where he meets boatbuilder Phil Robertson. Phil gives him a lift in his restored ring netter, the St Clair, up Loch Fyne to Ardrishaig, the start of the canal. Calum is impressed with local lock keeper David Provan's piping, but not with the weather, as it's pouring! There is so much rain the canal has to close for fear of flooding. It doesn't stop our heroes though as they walk on to Bellanoch, where Niall Iain spots an otter in the River Add. Calum heads on to Dunadd, cutting across the Moine Mhor, and the standing stones of Kilmartin, before reaching the ancient seat of the kings of Dalriada.
