Eglwys Faen Crawl Entrance

The entrance to Eglwys Faen Crawl sits tucked into the limestone landscape near Crickhowell, a proper caver's proposition rather than a casual stroll-through. This is a genuine horizontal cave system - you'll be squeezing through tight passages and ducking under low rock where the passage narrows considerably. It's not for the claustrophobic or anyone expecting a walk in the dark with good headroom.

What makes it worth the trip is the geology itself. The cave cuts through Carboniferous limestone, and you get a real sense of how water has sculpted these passages over millennia. Bring a torch (or three - caves eat batteries), wear clothes you don't mind getting filthy, and expect to be on your stomach at points. The whole thing takes a couple of hours depending on how far you venture and how comfortable you are crawling.

This appeals to serious cavers or adventurous walkers who want something more than a tourist cave experience. It's genuinely wild, which means it demands respect and preparation. Kids might find it thrilling, but only if they're older and not prone to panic in tight spaces.

Crickhowell itself is a lovely market town with decent pubs and shops, making it a natural base. Cwmdu Campsite sits just 4.8 miles away - close enough for a proper caving weekend. Check locally for access permissions before you go, and don't attempt this solo or in poor weather.
