Dorking Caves

You'll find yourself descending into chalky darkness somewhere near Tadworth, where Dorking Caves offer a properly underground experience in the heart of Surrey. These aren't vast cathedral-like caverns - more intimate tunnels that cut through the chalk, with the walls bearing the marks of centuries of extraction. The caves themselves are historical workings, evidence of how the area was mined for building material, and wandering through them gives you a real sense of what industrial Surrey looked like before the suburbs took over.

It's worth allowing an hour if you're serious about exploring, though the whole thing won't exhaust you. The caves work best for anyone interested in geology or industrial heritage - kids might find them a bit underwhelming after twenty minutes unless they're genuinely into that sort of thing. The ground can be damp and uneven underfoot, so proper shoes are essential.

The practical side: check ahead for opening times and admission costs before you head over, as information's thin on the ground. If you're staying at one of the nearby glamping spots - Surrey Hills Yurts is closest at under two miles away, or Henfold Lakes if you want something slightly further out - the caves make a sensible half-day addition. They pair well with a walk across the Downs; you're right on the edge of proper Surrey countryside here. Worth a visit if you're in the area, but don't make a special trip from London just for this one.
