Me and my family are going to Hayfield for 2 weeks over Christmas and New year and was wondering if there was any interesting explores nearby or within a 30 - 40 mile drive.
The lido Hugh mentions is actually at little hayfield very close to the pub there. You are well placed for the pumping/filter station at kinder reservoir and a few old stone mines on top of cracken edge but you can find dozens of places within 10 or 20 miles of there never mind 30 or 40 miles.
