For most a skiing holiday might involve a few runs down a gentle slope.
But for this self-defined 'lover of mountains' nothing but a vertical cliff edge would do.
Kilian Jornet, 31, was the first person to ski down Europe's largest vertical scarp - Troll Wall in the Rauma Valley, Norway.
Almost a straight drop to the ground the steep skier spent two and a half hours skiing down the 5,500ft mountain - known as Europe's largest vertical scarp.
Kilian Jornet, 31, spent two years training to ski down Europe's largest vertical rock face, known as the 'Troll Wall', in Norway
And he filmed the moment of descent on head cam footage that shows a terrifying drop.
Using picks to grip on to an ice sheet he slowly edges down the rock face but as soon as it levels out he slides using his skis.
Winding his body quickly to the left he slides around a metre down the mountain before switching to the right to descend further.
The 'Troll Wall' is around 5,500 feet tall with an average incline of 55 to 60 degrees - but it looks almost completely vertical.
And Kilian faced sliding powdered snow and huge sheets of ice as he carefully made his way down the potentially deadly mountain edge.
He told MailOnline: 'During the descent, I was very focused on what I was doing, as it is very exposed and you're not allowed to make any mistakes.

'However, I really enjoyed it, it was very exciting to discover this new route and all the sections in between.'
Trollveggen's mountain wall was thought of as impossible to climb before 1965.
But when a group of Norwegian climbers and another group of English climbers took 14 days to get to the peak on two different routes the site became more popular.
Adventurers now climb to the peak before spending the night on the rock face.
Kilian spent hours studying the trail and waiting for the best conditions before becoming the first person to ski down the mountain.
He said: 'On February 17, 2018 I went to inspect the route. However, I realised at once that the conditions were very favourable.
'In steep skiing the conditions aren’t ever perfect, so I realised that I had to try it no matter what.
'It was a very interesting yet demanding experience. The upper section is perhaps the most complicated, as they are probably the most vertical 200m that I have ever skied.
The 'Troll Wall' is around 5,500 feet tall with an average incline of 55 to 60 degrees - but it looks almost completely vertical
'Following that, there was quite a narrow couloir of 400m and then 100m of more skiable sections, but which were very icy and steep in parts.
It’s a very exposed route where you have to fully concentrate, but in the end the result was very satisfactory.'
The adventurer has produced a documentary, called Troll Wall , of his expedition.
