Bos Swallet

Standing at the edge of this gaping hole in the Mendip Hills, you're looking down into one of Somerset's more dramatic underground features. Bos Swallet is essentially a massive sinkhole where the River Lox vanishes completely into the limestone, creating an impressive natural funnel that's both fascinating and slightly unnerving.

Cavers know this spot well - it's part of the extensive underground network that makes the Mendips famous among potholers. But you don't need to squeeze through tight passages to appreciate what's happening here. The surface features alone are worth the walk, especially after heavy rain when the water thunders down into the depths.

Families with curious kids will find plenty to discuss about how water carves through rock over thousands of years. It's also a cracking spot for anyone interested in geology or just wanting to see something genuinely unusual. The walk from Cheddar takes about an hour across typical Mendip terrain - expect some steep bits and muddy patches.

If you're staying at one of the nearby sites like Cheddar Woods Resort or Wild Goose Glamping, this makes for a proper countryside adventure without travelling far. Just don't expect facilities or marked paths - this is raw Somerset landscape at its most authentic. Worth combining with a visit to Cheddar Gorge if you're making a day of it.
