Stone books

Up on the moors above Keighley, someone has arranged stones into the shape of open books. It's the sort of thing you stumble across and think: well, that's brilliant. The stones themselves are nothing fancy - just local grit laid out on the ground to read like pages - but the concept catches you. An art installation, memorial, or act of whimsy depending on who you ask. The view from up there sweeps across the Pennines, which alone makes the walk worthwhile.

It's best for walkers who don't mind a bit of moorland rambling to find it. Kids might enjoy the treasure-hunt aspect of locating the thing, though they'll need managing on the exposed ground. Photography types will love it - the stones contrast nicely against the heather and grass, especially in late afternoon light. Most people allow 30 minutes to an hour once they've walked up from the nearest car park, though the actual site itself takes five minutes to look round properly.

Being free and accessible (as far as we know), it slots perfectly into a wider moorland walk. You're close enough to Bronte Country Park for the literary crowd, or use Upwood Holiday Park or Woodsworth Exploring as a base if you're camping in the area. Combine it with a walk down to Haworth or across to the Pennine Way trails - the stone books make a decent waypoint rather than a destination in themselves. Go when the weather's kind. The exposed moors turn grim quickly when it closes in.
