During this trek we offer you the opportunity of walking on a 20.000-year-old  glacier, with the help of crampons. You can feel the amazing sensation of standing on ice and walking the Martial Glacier from end to end.

Besides, you will admire a magnificent viewpoint of Ushuaia and its bay and as if it wasn’t enough, of Beagle Channel, Bridges Islands and the Chilean Williams Port and Navarino Island.

This trek is ideal for those who are looking for a big outdoor adventure and incredible sights, just a few hours far from Ushuaia City.

About the 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 Beltrame Muschietti


August, 2023

Sebastian was unable to take us, but arranged for Facundo Ferrari. He was amazing from start to finish and we had on e of our best days of a two week trip. Outstanding!!!!!

Facundo was amazing! I have some climbing experience and my partner had never climbed before. Similarly, my partner speaks Spanish but I only speak English. Facundo not only guided us expertly through several routes but also taught us a lot about Ushuaia. The experience does involve a 20-30 minute hike to the climbing location so be prepared for a trek. But it was a fantastic experience and highly recommend being able to say you climbed in Patagonia :)

Marine was a really wonderful guide and she made the 3 day trek around Tierra del Fuego a great pleasure for us. She is very knowledgable and a very professional guide. Marine also helped us with renting clothes that we needed and went the extra mile to make sure we had everything we would need. I would definitely recommend this trek as well as Marine and Seba. Booking and paying through explore-share was also very easy and efficient. Thank you to all!

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

Amazing tour with Guias del Sur! Jeremias was an outstanding guide we strongly recommend for your tour who knows all about the landscape, its plants and animals and a lot of inside stories and all climbing routes and trekking tours in the area!

Sebastian was friendly, professional, knowledgeable, and thoughtful in his safety decisions. He is also just a great guy to ski with - we had a blast with him!

The trip was great! Sebastian's colleague Ignacio catered it exactly as I have envisioned the trip to be according to my skills and background experience. He was patient and helpful when I struggled in certain moments and he taught me a lot of important safety details on various aspects of the activity, which was what I expected. Overall, a fantastic three days and will definitely return if I have time next year!
