About the guide

Mountain Guide

I graduated in Buenos Aires as Universitary proffesional in tourism and as a Mountain Guide in Mendoza province. I started working in adventure activities, horseback riding and mountain ascents. Then i moved to Patagonia that was my dream place for living and thanks to this profession it became in my place for working and personal development.

After several years of experience working in these mountains and numerous trips around the world looking for adventures and experience, I managed to unite both professions in an objective, so Serac Expeditions arose. In the last 15 years working with Serac, I have organized trips for thousands of people and personally guided hundreds of them in diverse and remote places in Patagonia, Chile, Peru and Bolivia.

Today my passion is not only guiding but also organizing special and personalized trips for people who enjoy exploring in nature and at the same time push their limits. My ideal is to provide a safe trip, spend a good time togheter with my clients and be flexible to provide a great experience and memories. To do this I work with a group of guides that share my ideals and way of working.

What people are saying about Diego



Explore Share - Set me up with Serac Operations - so an excellent 5day traverse - challenging at times (with a fairly full pack)! Perfect Autumnm weather. Serac provided an excellent very experienced guide - Matias Passerano - and he did a great job.



Our trip to Patagonia was a once in a lifetime opportunity that checked off all the boxes! We had excellent guides, the accommodation was perfect and each day was more beautiful than the last. Explore-Share ensured we connected with the appropriate people whenever we had questions and the customer service was 5 star!


This was a great trek. The organization by and support from the Serac team was top notch. I reserved well in advance and the communications I received before my trip were always clear and timely. Once I arrived in EL Chalten, everything was smooth. Hostels were arranged and the team arrived to walk us through the trek. The guides were knowledgeable and helpful, the trek was challenging but the views were rewarding. Highlights were camping in "iceberg bay" and the hike up to Paso del Viento. The shuttle back to El Chalten was timely and even came with a complimentary beer! The trek is tough so not for the mentally unprepared.


My husband and I had a great experience with Serac - we did the El Chalten Mountain Escape trek and it was fantastic. Our guide (Christian) was very knowledgeable and kind; food was excellent and they even had wine portered to our campsites each night. All in all, highly recommended!


I first saw the opportunity to trek the South Patagonia Icefield when I was in El Chalten 3 years ago. I finally took the plunge this year and signed up with Serac Expeditions for their late-February departure - best decision ever! The Expedition itself is incredible! Only about 100 people/year undertake it so you get to see a part of Patagonia that few others have experienced. And of course the scenery is amazing. I won't lie - the expedition is challenging (especially for a relatively small female), but if you go in with reasonable fitness and the right mental attitude, it is totally doable and absolutely worth it. It also helps when you have decent weather :) Serac Expeditions are wonderful! They are very responsive and helpful throughout the whole process of arranging the trek, provide excellent equipment, and work with incredible guides (million thanks Juan and Rafa - you guys are awesome!). They also include some special surprises along the way, but you'll have to sign up yourself or read my blog posts to find out what ;) 100% recommend Serac Expeditions and this trek. I am now wanting to return to do the Marconi - Estancia Cristina expedition with them, but this time at the start of the season (November) to experience the Icefield with snowshoes rather than crampons.
