Pin Hole

You'll find Pin Hole tucked into the limestone cliffs near Worksop, a cave that's been pulling in curious visitors since Victorian times. It's genuinely small - the entrance is modest, almost easy to miss if you're not paying attention - but that's rather the point. The cave itself is short and straightforward to explore, making it ideal for families with younger children or anyone who finds crawling through massive caverns a bit much.

What makes it worth the trip is the setting more than the spectacle. The approach takes you through pleasant countryside, and there's something rather satisfying about poking around a proper archaeological site rather than a polished tourist cave. Pin Hole has serious credentials too - Palaeolithic remains have been found here, which adds genuine weight to what you're looking at.

Allow an hour including the walk and the cave itself. It's free to visit, though there's no infrastructure to speak of - no café, no gift shop, nothing like that. Go when it's dry; mud and caves aren't a great combination. Given you're staying at one of the caravan parks near Clumber Park or Poolsbrook, Pin Hole works perfectly as a morning expedition before heading to the larger attractions in the area. Clumber Park itself is only five or six miles away and offers far more in terms of walking and facilities, so you could easily combine the two.
