It is run by this man, Trevor Potts, and it is just beyond the village of Kilchoan on the Ardnamurchan peninsula.
He's also a kayaking legend, but more of that later.
I believe it was this book Cool Camping Scotlandwhich placed Trevor's campsite number two. (If not that one, then one of the Cool Camping series). Here's their website.
The Guardian newspaper picked up on this, swiftly followed by The Times, both of which included Trevor in their guides. He provided the photo, they brought him visitors. He had to increase the bandwidth on his website - ardnamurchanstudycentre.co.uk.
I called in on Trevor as I cycled past. He's had a great year, but not too many kayakers. Which is surprising as there are load around and he is mentioned in The Scottish Sea Kayak Trail.
Trevor recorded interviews at SeaKayakPodcasts.com. He was a member of the first western team to kayak the Bering Strait from Alaska to USSR. He also recreated Shackleton's famous escape from Elephant Island. They're worth a listen, and if you're looking for a nice campsite base for a few days paddling, you know where is cool.
