In reply to climbwhenready:
> Depends which bit of Nidderdale, but a list of things that aren't in Nidderdale but are close by in the Dales are:Stump Cross CavernsBilly Bob'sWalks in the Bolton Abbey estateTroller's Gill (might still be flooded from winter)The Embsay-Bolton Abbey steam railway (n.b. if you are thinking of going to Bolton Abbey as part of this, the Bolton Abbey station would be better named 'Bolton Abbey Parkway' as part of my theory that 'Parkway' means 'nowhere near')
You can have quite a good day for kids near us - the steam railway in Embsay, then Hesketh Farm which is one of the better ones of the genre, and the Yorkshire Dales ice-cream farm (Billy Bob's) has a splendid "play barn" with ropes and swings, plus a good playground. And the Bolton Abbey estate usually do an easter egg hunt or something down at the Cavendish Pavilion as well. So that's four good activities within about 4 miles of each other.
