These potholers really know how to ‘get down’ and party after holding their Christmas bash 200ft underground – in Britain’s largest cave.
The group – called The Tuesday Diggers – decided to hold their annual festive party in a massive cavern they discovered in September.
A gruelling hour-long descent led the five revellers to the Frozen Deep, a 98ft-high 200ft-long chamber in the Mendip Hills near Cheddar, Somerset.

The pals lugged Christmas decorations, party hats, food, mulled wine and even a Christmas tree through 150ft of narrow rock passageways to liven up the cave.
They sipped their wine while listening to carols being played on an MP3 player – in a giant chamber the height of a cathedral.
Caver Martin Grass said: “It was definitely the most interesting Christmas party I have ever been to, especially because we actually discovered the giant chamber.

“The key thing is that you’re not going to go down into a cave and get drunk – that’s just stupid.
“We had one small glass of mulled wine each, and still had a great time.
“Christmas Day is for drinking – the party in the cave was for pure enjoyment.”
The sales and marketing director, from Cheddar, has been caving for decades but reckons this was his best experience underground.
He added: “It was amazing – everyone had such a great time.”
