YOUTUBE star and wild swimmer Calum MacLean will be sharing his passion for the sport in a new TV series.
In the programmes, Into the Water/Dhan Uisge which starts on Thursday on BBC Alba, Calum reveals some of his favourite remote places to swim in Scotland.
Calum has a huge social media presence with 1.8 million views for his 60-second “midgie challenge” on Skye and his wild swimming tips, ice swims and vlogs regularly attract thousands of views on Facebook and Twitter.
His chosen settings are far off the beaten track and some can only be accessed by boat or after a long hike.
Calum says: “I love to swim outdoors alone with no living person to be seen”.
The locations featured include River Douchary, River Garry, the islands in Loch Maree, Spar Cave on Skye, Loch Coruisk, Easdale Island and Sanna, Ardnamurchan.
He also takes up a challenge to swim through punishing currents from Seil over to the island of Luing.
Calum enjoys the challenge of swimming in places which stretch his tolerance of the cold and which offer additional feats of endurance.
But he says that there are plenty of places which are suitable for novices.
“There are wide open beaches in Scotland which would be safe for someone not used to swimming outdoors,” he says.
“All you really need is a swimming wetsuit and you don’t have to swim for long to get a big rush of endorphins. Then you feel amazing for the rest of the day ? it gives you a real buzz.”
? The first episode of Into the Water/Dhan Uisge will be broadcast on BBC Alba on Thursday, May 25 at 10.30pm, followed by a further nine episodes on successive Thursdays.
