    Are you ready to live a unique 5-day ascent to the San Jose, an amazing volcano of the Central Andes?

    Just 90 kilometers from Santiago the Chile, in the beautiful green reserve of Cajon del Maipo, rises the San Jose volcano (5,856 m). It is a border mountain and one of the highest peaks in the central Andes mountain range.

    The San Jose volcano is a perfect summit for people who are taking their first steps in high altitude ascents. That is because of its easy access and its ascent route, which does not present major technical difficulties.

    In fact, it works perfectly as a preparation experience before a bigger goal, like climbing the Ojos del Salado Volcano, the highest volcano of the world.

    The complete program I am leading in the San Jose volcano will take us 5 days. We can use donkeys to carry the load and help you reach the base camp at 3,500 meters of height.

    This expedition requires a good physical condition and an adequate prior acclimatization.

    So, if you want to join me on this amazing program contact me as soon as possible. It will be a pleasure for me to guide you up to the roof of the San Jose Volcano!

    What People are Saying about Gastón Oyarzún


    Gastón is incredible and so professional! He met with us before the trip to make sure we were prepared and to go over all the details which was extremely helpful. Dinners with his great cooking and good conversation were one of my favorite things. When we hiked, he set the perfect steady pace for acclimating to the altitude and not getting too tired. This trip wouldn\'t have been the same without Gastón. I wouldn\'t go with anyone else!

    We had an incredible time on our trip! Gaston was amazing, and we were very fortunate to have him as our guide. He has spent a lifetime hiking in Chile, and it reflected in his planning and preparation for the trip. With his help we were able to push to the top, and make awesome memories along the way!

    Gaston Oyarzun is obviously an excellent climber/mountaineer, but he lacks a great deal of organization/logistics. This applies to all aspects of the expedition, from food to itinerary.
