Well I love Edale as it is local for me as I'm from Manchester, so its between Preston and Hull I supposeFieldhead Campsite, Edale, Peak DistrictEdale being where the Mass Tresspass was in 1930 ? and Britains second highest peak 'Kinder Scout' of what my little girls climbed at aged 4 & 6 yrs old. Theres also Mam Tor and plenty of not so hilly walks. No big water though theres plenty of Brooks. Oh there is a big water, on the other side of Kinder Scout', Torside Res, Woodhead Res & Ladbower Res although with a bad leg I doubt you'll be doing any climbing over the Kinder.
There's a fantastic site up above Silsden, but I can't recall the details.
