Yorkhouse Cave

Yorkhouse Cave sits tucked away in the Somerset landscape, a genuine slice of underground Britain that doesn't require booking or paying an entrance fee. You're looking at a proper limestone cavern - the sort of place where the air changes temperature the moment you step inside, and you'll want to mind your head on the way down. The cave itself is modest in scale compared to some of the showier attractions in the Mendips, which honestly makes it feel more authentic. You can explore the chambers, see the rock formations, and get a genuine sense of what Victorian explorers must have found when they first ventured in.

It's the kind of stop that works brilliantly if you're based at one of the nearby campsites - Somerset Glamping is less than a mile away, making it perfect for a morning adventure before heading out for something bigger. The Batch Campsite and Mendip Basecamp are also within easy reach, so families with kids who fancy something a bit different from the usual park activities will find it worth the detour. Wear proper shoes though; the ground is uneven and damp. Allow 30 to 45 minutes to explore without rushing.

Bristol is close enough for a day trip combination, but honestly, Yorkhouse works best as part of a wider Somerset caving or walking day. It's free, it requires no advance planning, and there's something rather satisfying about discovering a cave entrance and just getting on with it. Not Instagram-famous, which is precisely why it's worth your time.
