> Bridestones is a tricky choice... hard to get info on it these days as people have trashed it so the guidebooks omit detail. Widdop has some nice easier bouldering mentioned for the first time in the new YMC guide... nothing on the routes is kid friendly. For bouldering with kids I'd, recommend Buckstones below the road (roadside on the A640 on the Huddesfield side of Denshaw). Another good venue for bouldering would be Blacktone Edge in the Lancs bouldering guide.
Widdop will be green and sopping and a bog around the boulders at this time of year if past experience has been representative! I'd say Woodhouse Scar or Hep Quarry.
Bridestones is great and it's not too hard to get to parts of it if you know the right places, but it's not somewhere to be promoted as the stone is very worn and particularly if not bone dry deteriorates quickly, so it's locals only really.
