For what’s possibly the weirdest Valentine’s Day ‘treat’ ever, a company is inviting climbers to scale an X-rated wall made out of stone penises and vaginas. (WARNING - photos above might be NSFW)

People with a strong grip will be encouraged to mount the rock hard wall, where all the handholds are made in the shape of genitals, bottoms and boobs.

The odd installation, by design company Bompas & Parr, will be on display in south-west London on February 11.

It was originally created for an exhibition at the Museum of Sex in New York, and now Londoners have their chance to explore the erogenous zones of Grope Mountain.

A spokesperson said: "The installation is inspired by modern climbing walls and made with custom holds, orifices and appendages - many cast from volunteers' anatomies from the original show.

"As climbers mount the wall, working their way towards the ultimate objective, being crowned ‘King or Queen of Grope Mountain’, they engage physically with the holds and cerebrally with the carefully choreographed routes.

"This journey encourages a rethink of the participants' own body."

The willy wall was made in collaboration with The Climbing Hangar Group, which created the original handholds.

Harry Parr, partner of Bompas & Parr, said: "Climbing walls are perceived as a place for sport, well-being and fun, but they can be erotic too.

"Gripping and tugging yourselves up with our sensual holds is this year's perfect date for those looking to show off their strength, stamina and flexibility."

London Grope Mountain is at The Climbing Hangar, in Parsons Green Lane, SW6 and will be open from 7-10pm.

Tickets cost £10 from, and visitors must be 18 and over.
