>>429249 In the Lakes, Dubs Hut and Mosedale Cottage are about the only ones you can overnight in, though mosedale is suitable to pitch tents all around too. There's a drinkable stream there too.
I havent' been up to Dubs hut in years so I cant really remember if you can pitch around it. I just remember it being really rocky there.
