Tha Niall Iain Domhnallach agus Calum MacAmhlaigh air an uisge 's iad a' siubhail air a' Chanàl Cailleannach. Tha na balaich a' seòladh air Loch Nis gu Cille Chuimein, far am faigh iad air na baidhsaigealan aca, 's a' cumail orra sìos Slighe a' Ghlinne Mhòr. Tha Niall Iain a' dol comhla ri criutha a' Vic32, an aon pufair ann an Alba a tha fhathast ag obair, aig Cille Chuimein.

'Se obair teth a th'ann, ach tha an sean bhàta seo a' cordadh ris. Aig Geàrr-Lòchaidh tha Calum a tadhal air Taigh Achadh na Cairidh, dachaigh Chlann Chamshroin, far an do ionnsaich na Comandos na sgillean aca, mus tèid e dha Carragh nan Comando aig Drochaid an Aonachain. Tha Calum agus Niall Iain a' strì comhla san Beast Race, rèis 10k le cnapan-starra sa pholl 's anns an uisge ri taobh Loch Nis. Tha iad a' crìochnachadh an slighe aca aig Neptune's Staircase, an cursa as fhàide ann am Breatain tro thuill-dhorais, 's le seallaidhean àlainn de Loch Linnidh.

Niall Iain Macdonald and Calum Macaulay take to the water as they explore the Caledonian Canal. They cruise down Loch Ness as far as Fort Augustus, where they get on their bikes and cycle the Great Glen Way. Niall Iain joins the crew of the Vic32, Scotland's only operational puffer, at Fort Augustus. Shovelling coal is hot work, but he is still charmed by this wonderful old boat.

At Gairlochy, Calum visits Achnacarry House, seat of the Cameron clan and where the Commandos honed their skills, before visiting the monument in their honour at Spean Bridge. Calum and Niall Iain both compete in the Beast Race, a 10k endurance race through water and mud on the shores of Loch Ness.

They end their journey at Neptune's Staircase, Banavie, the longest set of locks in Great Britain, with a stunning view across Loch Linnhe. Show less
