Millstone How Hill

You get a proper fell walk out of Millstone How Hill rather than a quick stroll, and that's the whole appeal. It's a modest peak above Barnard Castle in County Durham, the kind of place locals know about but tourists often skip. The summit itself isn't dramatic - there's no trig point or cairn to gather around - but the walk up rewards you with wide views across the Pennine moorland, particularly good when the light's right in late afternoon.

The ascent is straightforward, nothing technical, which makes it manageable for reasonably fit families with older children. Walkers will appreciate the solitude; you won't be queuing or dodging crowds here. Allow a couple of hours there and back depending on your pace and how long you linger at the top. It's free to access and open year-round, though it's best visited when conditions are dry - boggy underfoot when wet.

Fit this in as a half-day walk when you're staying at Leekworth or Mickleton Mill caravan parks, both within five miles. The nearby market town of Barnard Castle itself has the ruined castle and river walks if weather turns, so you've got a solid backup plan. It's not a destination in itself, but if you're based in the area for a longer stay, it's a cracking way to stretch your legs and get above the valley floor without serious effort.
