I’ve stayed (with the kids) at the one just east of Hope on the main rd – laneside farm. You wouldn’t go wrong with it but I wouldn’t strongly recommend it either – location good, clean and well kept site. Don’t think it was especially family-orientated wrt noise etc – We stayed at Fisherground in the lakes recently which was clearly anti-pishhead, with plenty of rules and regs, and there’s nothing like that there.
It’s also good (IMHO) if there’s something to do for the kids on the campsite, other than throwing stones in a river and playing with sticks. This place had nowt, really. Not looking for a continental-style games palace or anything, but a wee adventure playground or similar is nice to keep them occupied for an hour or two.
