I stayed at the Great Langdale campsite in Cumbria and it had its ups and downs.
Firstly I was staying during a wet period in the middle of winter, so the field being waterlogged in placed was perhaps to be expected. There were a few bits where it was just too stony for me to pitch my tent too so I had to pitch it three times until I found somewhere OK.
The facilities are pretty good. The showers are free and there seems to be plenty of hot water available for cleaning yourself and your pots and pans.
It has a drying room, which was great, if crowded. Its open 24 hours a day if you need it – and I put some stuff in at 3am once as I was trying to dodge the torrential rain.
The shop has all the essentials and the people who worked there were very friendly. Note – they DON’T sell loaves of bread but they DO sell baguettes – and they are baked on site so they’re warm and yummy! And it was only 50p when I was there (January 2012) so good value too.
Toilets were pretty clean and they had one of those hand dryers you dip your hands into rather than hold underneath, a bit like a Dyson Airblade. The road through the campsite became a river temporarily after heavy rain but I imagine this was the result of already waterlogged ground refusing to take run-off. Can’t fault the location either. If you’re going to go mountain walking in England this is one of the best places to camp. I mean top 5, not just “generally”. The mix of family-friendly walks and high fell tops is great, plus there are well-used routes to other parts of the Lakes too.
One thing – make sure you book your place in summertime. It gets really popular so book as far in advance as you possibly can. If you’ve just hiked over the fells and have nowhere else to go they probably won’t turn you away but if you’ve got a car, forget it.
