I’m Marin Obert, born in 1960, I became candidate Mountaineering Guide in 1979 and I’m Guide from the 1980. At home I’ve always “breath mountain air”, because three of my brothers were Guides and also my grandfather was a Guide! I’ve been in the 80s in an expedition in Nepal, and I loved that places. I came back to that part of the world several times, for trekking, with friends and then with clients. I climbed the Shisha Pangma, the only one 8000 m peak of my career. I love my work, also if I don’t practice it all the year long. The area that I know better is the Monte Rosa, but I go often also in new and different places.

Marco Spataro, Guide and photographer, lives in high Ayas Valley, close to the Monte Rosa, where he climbs its peaks alone or with his clients. When he was a child walked with his father in all the mountains of Aosta Valley, by feet or by ski. And his father, Remo, gave to him his love for photography and mountain. This love became for him a work. During his hikes, in the Valley and abroad, he looks for the better light and framing to fix them with his Nikon. The images give importance to the love for the landscape and to the emotions. Marco works for mountain and tourism magazines where he publishes articles and itineraries.

Born in 1974 in the surroundings of Novara and moved in Ayas Valley at the age of 20, lives now with his wife and his three children in Antagnod. The passion for the mountain lead him to his first steps on the glaciers of Monte Rosa climbing all the peaks of the chain by different roads. He went to the Himalayan glaciers, on the Shishapaghma, and to the South American glaciers, on the Yshinca, Hurus, Tochliaracu and Huascaran. He knows the best places in Ayas Valley and for him it will be a pleasure to lead you wherever you don’t dare to go.
