Since I’ll be in the sea for a while today, I have to make sure I’m wearing enough. I have socks, my wet suit, two caps and two under-garments under the wetsuit. The sea could be “Baltic” today. This is Sanna Beach, in Ardnamurchan – the most westerly point on the mainland. I’m just looking for any creatures that might be here – crabs, lobsters or even a basking shark. Nothing here! Every time I come to the beach, I feel like a little child again.I just want to splash about in the waves. Well, this isn’t quite a Hawaiian pipeline, but it’s still fun. Careful, Calum! You lost a camera once, doing this. 10/10! Narly! If I were to swim out now, there would be nothing between me and America. Well, apart from Mingulay, Barra and Coll, but every swim begins with a single stroke. .
