Norber erratics

Boulders the size of houses litter the hillside above Clapham, dropped here by a glacier about 20,000 years ago and left stranded on the landscape like some giant's game of skittles. The Norber erratics - that's the geological term for these ice-age refugees - sit on limestone pedestals, which is the real puzzle. The rocks themselves are harder millstone grit, so they've protected the softer stone beneath from weathering, leaving them balanced on precarious-looking columns.

It's a proper walk to reach them. You're looking at roughly two hours from Clapham to get up there and back, gaining maybe 400 metres in height. The path winds through woodland first, which is pleasant enough, then opens onto moorland with decent views across the Dales. The erratics themselves - there are loads of them scattered across the fell - aren't monumentally dramatic to look at. They're interesting rather than stunning, honestly. But if you care about geology or fancy understanding how the last Ice Age physically shaped this corner of England, it's worth the climb.

Families with strong walkers will manage it; younger kids might find the initial excitement wears off once they realise it's just rocks on rocks. Base yourself at one of the nearby campsites - Dalesbridge is closest - and pair it with a visit to Ingleborough Cave down in Clapham village, which gives you a proper half-day outing. The walk itself is free, obviously. Go on a clear day when visibility is decent, otherwise the moor just feels dull and grey.
