Thanks to our partner Marmot, we got the opportunity to ask professional steep skier Gilles Sierro some very interesting questions. We’d like to introduce you to this friendly Swiss athlete and explain what it is about steep skiing that he loves so much. We’ll also be sharing with you some good tips you can use if you fancy trying steep skiing for yourselves.

Who is Gilles Sierro?


Gilles Sierro is, first and foremost, an extreme skier - this Marmot athlete has specialised in skiing down very steep slopes. He grew up in Hérémence, southern Switzerland.

His village is halfway between the legendary ski regions of Chamonix and Zermatt, in the heart of the Swiss Alps. Gilles has been skiing since pre-school, and could probably ski before he could walk.

Under his dad’s wing, Gilles Sierro took part in alpine ski races until he was 16. After that, he switched to freestyle skiing and competed in the Half Pipe World Cup events. Then he began working as a mountain and ski touring guide - a skier through and through. Gilles Sierro Ski Tour Winter Snow Today, Gilles enjoys guiding his clients around his home mountains in Chamonix and up the Matterhorn, but his heart still belongs to steep skiing, which is why he takes some of his clients down routes steeper than they previously thought skiable.

Last year, he became one of only three skiers ever to successfully complete two of the most difficult descents in the area: the north face of Mont Blanc de Cheilon and the north face of the Pigne d’Arolla.

His next goal is to link up 3 radical steep descents: the east face of the Matterhorn, the northeast face of the Liskam and the Marinelli Couloir (the longest couloir in Europe with a vertical descent of 3,000 metres). We’re excited to see how it goes!

What is steep skiing?


Although the term “steep skiing” may seem self-explanatory, it’s actually a bit of an understatement. Involving slopes with inclinations of up to 60°, steep skiing requires concentration, preparation, careful observation of the environment, good risk assessment skills, the best equipment available and, of course, excellent skiing ability. Steep skiing is not just an art, it’s a way of life.

When asked what steep skiing means for him, Gilles said that “steep skiing can mean a lot of different things to a lot of people. For me, it’s like doing solo alpinism on skis. Skiing where other people dream to climb. It often means a lot of technical preparation, no fall zone, exposed skiing”.

He continues: “The risks are very high, but so are the rewards. When skiing in this area, feeling tiny and fragile, you’re connected with the real you. Life is very simple up there, all that matters is the next turn, and then the next turn and so on. There’s no room for distraction and the endless questioning of daily life.” Steep Ski Marmot Athlet Gilles Sierro Turn Turns World Winter We went on to ask him a series of questions:
