Boreham Cave

You'll need to work for this one. Boreham Cave sits tucked away near Skipton in North Yorkshire, and it's not the sort of attraction that announces itself with a visitor centre or gift shop. The cave itself is modest - a natural limestone formation that demands a bit of scrambling to explore properly. Not vast or cathedral-like, but genuinely atmospheric once you're inside, with decent geological interest if you know what you're looking at.

This is squarely for walkers and geology enthusiasts rather than casual day-trippers. The approach involves moorland walking across what can be boggy terrain, so proper boots are non-negotiable. Kids with adventurous parents will enjoy it; younger children or those expecting an easy tourist experience will likely find it frustrating. The cave itself takes maybe twenty minutes to explore thoroughly, so you'd want to build it into a longer walk across the moors.

The location is handy if you're staying at Wood Nook Caravan Park - it's only six miles away, making it a sensible half-day excursion. The surrounding moorland is worth wandering regardless of whether you venture into the cave itself. Go on a dry day; the approach becomes a genuine slog in wet weather, and the cave's appeal diminishes when you're soaked through. Skipton is your nearest town for supplies, and there's plenty of other walking country in the area to justify the trip even if the cave turns out smaller than you'd hoped.
