Mountain Guide
Mountain Guide, GEM-AAGM Ski Guide, UIMLA, AIARE level 2 from Argentina.
I was born and live in Ushuaia, the southernmost city in the world! I've been skiing since I was 2 years old, and competed as a ski athlete in a Nordic ski and Biathlon world ski championships, world cups and in the winter Olimpic Games Torino 2006
In 2007 I retired from professional competitions to focus on my guiding career. I trained on rock, ice and mixed climbing skills as well as guiding techniques and became a mountain guide in 2011 at the Argentinean Mountaineering Guides Association (AAGM). In 2017 I completed the guiding courses to become also a certified Ski Mountain Guide GEM-AAGM.
I've done a large number of technical climbs at the Darwin Range and Patagonia while many of those are new lines

What people are saying about Sebastian
Agata
My guide, Micaela from Patagon agency was very knowledgeable and likeable. The three day trek covered everything from glacier and high mountains to the gentle walks in the forest and on the turf marshes. Gear, food and transfers were provided, we didn’t lack absolutely anything. I rarely hike with guides, but I thoroughly enjoyed this experience!
Don
Sebastian was great to work with. He has deep experience in the region and guided me professionally for a fun, rewarding day on the Marital Glacier.

We were very pleased with our guides, and our overall experience. We were contacted two days before our trip and the team was very helpful getting us prepared. Transportation was a snap. Our guides, Sebastian and Marine, were kind, helpful, engaging and knowledgeable.
Mitch
Sebastian was a great guide! We felt very safe and it was really fun getting to know him. We liked him so much we decided we would do a second trip while we are in town. If I ever come back to Ushuaia, I will definitely track him down for more trips
