Castle Hill

The walk up Castle Hill rewards you with proper views across the Cheviot foothills and down towards Alnwick. It's a straightforward hike from the village of Alwinton - nothing too demanding, maybe forty minutes to the summit depending on your pace and how often you stop for breath.

Once you're up there, the reason for the name becomes obvious. The Iron Age fort that once occupied this spot has left earthworks that are still legible if you know what to look for - a rampart running round the hilltop, worn smooth by centuries of weather and sheep. On a clear day you can see for miles, which is precisely why someone decided to build a defensive structure here two thousand years ago.

This is walker territory, full stop. Families with young kids might find the climb a slog, and there's not much to actually do once you've arrived except stand about looking at the view and taking photos. That said, if you're hiking through the Cheviots anyway - and you should be - Castle Hill makes a logical addition to a longer loop.

Getting there is free, naturally. The nearest town is Alnwick, about eight miles away. If you're camping at one of the sites nearby - Middlemoor Farm Holidays or Doxford Farm Camping are both within spitting distance - this works as a half-day outing. Combine it with walking in the broader Cheviot range and you've got a solid few days' worth of fell work.
