The series of photos shows the friends taking turns as they stand on top of a boulder that is wedged between a mountain crevice in Norway, with a direct drop of nearly 800ft.

The incredible experience provides impressive views for those who are brave enough to step foot on the boulder, but those who are afraid of heights would become weak at the knees and think better of it.

Kjeragbolten – the official name for the boulder – is located on the edge of the Kjerag mountain in Rogaland, Norway.

It is situated more than 3,500ft above sea level and is a popular photo spot for thrill-seekers who are willing to risk their lives for a memorable holiday photo.

Despite the rain making its surface slippery the group of visitors in these photos ventured onto the boulder and posed with their arms in the air or a thumb extended as other tourists waited their turn.

Software developer Ronny Randen, 39, took the photos while he was travelling with five friends to climb Preikestolen, also known as Pulpit Rock.

He said: ‘During our visit if was a rainy, and the boulder was actually a bit slippery. There's a little path on the left side where you can jump onto the rock.

‘It's hard to describe the feeling of standing on the boulder. After walking up the mountains your legs are a bit tired, and the idea of jumping onto, and balancing on, a slippery boulder hanging above a fjord seems like a really bad idea.

‘But, to be honest, it's not hard getting out there, and it is well worth it.’

Mr Randen, dressed in blue, can be seen posing on the boulder with his hands in the air and in one photo, taken from a distance, shows the stunning view and terrifying drop.
