Went here last summer on my own in the car and tent. Lovely site right on the north coast of Scotland. Dramatic scenery on route. Amazing few days away. There's a bar on site and a little shop and petrol station round the corner. If you haven't been to the west coast or north of Scotland you are missing out. The best scenery in Britain. Also went here My first camper trip I hired a splitty for a week in Devon (I bought my bay 4 weeks later) and went to lands end so I thought I'd better go here whilst I was in the area.
I'm planning a trip to Islay now I've read your trip. Last year I did 4 days 3 nights. Durham - Aviemore, Aviemore - Durness, durness - glencoe, glencoe - Durham. But in the daily doing 300 miles ish a day. Was a great trip, first time solo. Great doing what I wanted when, stopping where I liked and eating what and when I wanted.
