Philosophy

Those who climb with respect, descend with wisdom.

A passionate mountain lover living with an ambitious and respectful perspective, I believe that my way of experiencing life in this place goes beyond just taking advantage of its natural resources. It's also about being conscious of the place I am living in, respecting it, appreciating it, and interacting with it in the most fun and beautiful possible way.

About me

Hi, I'm Sergio.

«For me, the mountains are not a stage to feed the ego; they are a temple where I practice my religion.»

Who I am

I'm Sergio San José, or as everyone knows me, Sanjo. I'm from Aragon, Spain, from the Pyrenees, and I've been living in Chamonix since the winter of 2018. I consider myself a passionate, cheerful, resilient, social, and respectful person, with the intention of making the most of, growing, and learning from every experience. Over the years, I have explored wild and remote mountain environments through a wide variety of activities. This journey has given me a refined ability to read the terrain, understand where conditions are likely to be favorable, and choose the right place at the right moment to share meaningful experiences in the mountains.

What I do

I am a Mountain Guide and graduated in Tourism. I've been skiing since I was a child, and I love it, just like going to the mountains and connecting with nature. I really enjoy and practice climbing, mountaineering, trekking, biking, yoga, slackline... also passionate about traveling, cooking, gardening, animals, spirituality, meditation, astrology, reading, sustainability, music, photography.

FAQ

Everything you need to know

Can't find your answer? My virtual assistant helps you instantly, or write to me directly.

Do I need previous experience?

Most day routes require no experience: moderate fitness and the will to walk for a few hours is enough. For Mont Buet and the multi-day treks, previous mountain experience is recommended. I'll help you pick the right one.

What gear do I need?

In summer: hiking boots, poles, backpack, water, food, layered clothing and sun protection. In winter, also: snowshoes, poles with snow baskets, waterproof boots, warm technical clothing and sunglasses. If you're missing something, I'll tell you where to rent it in Chamonix.

How much does an outing cost?

Trekking from 150€, snowshoeing from 175€ and multi-day treks from 220€ per day. The final price depends on the route, group size and date: message me and I'll send you a personalised, no-obligation proposal.

What if the weather is bad?

Safety comes first. All routes depend on mountain conditions: if the weather doesn't cooperate, we adapt to a safe alternative or find another date together.

Where is the meeting point?

Outings start in the Chamonix-Mont-Blanc valley. The exact spot (station, car park or cable car) depends on the route and I'll confirm it when you book.

Can I come with kids or as a private group?

Of course! I organise private outings for couples, families and groups of friends, adapting the route to everyone's age and level.

What do multi-day treks include?

They include the guide, itinerary planning, a safety briefing and optional luggage transfer between stages. Accommodation is in mountain huts, guesthouses or small hotels. Travel to/from the start, meals (unless specified) and personal equipment are not included.

How do I book?

Through this website's assistant, on WhatsApp (+34 648 219 451) or by email (sergiosanjose@me.com). Tell me the route, the date and how many of you there are, and I'll confirm availability.
