San Jose volcano guided ascent

San Jose volcano guided ascent | undefined

The San Jose volcano is a perfect mountaineering experience as a first approach before bigger goals. Join Gaston, a local ACGM mountain guide, in this 5-day adventure!


5 Days

Jan - Mar, Dec


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



We summited Ojos del Salado on December 8th, 2023. We where a small and nice group of 3 mountaineers and 2 guides. Gaston was a very friendly senior guide. Very helpful was his admirable experience as a mountain guide. He provided a reasonable and balanced program consisting of acclimatization hikes, driving and rest days. Explore-Share was the only provider who offed me this expedition for a reasonable price at suitable dates and assisted very well in finding the right guide. It was an unforgettable trip I can recommend to everybody, who loves mountaineering and outdoor adventures.



We loved Gaston - he was very nice - BUT - one of the team members was not prepared - at all - for this type of climb which significantly hampered the performance of the other team members. I would STRONGLY encourage a stronger process of weeding out those who have no business signing up for such a climb - I will admit, my entire experience was 'ruined' because of the weak climber - we had to take long, long, long breaks in order for her to catch up making the rest of us extremely cold - it was so unfortunate - additionally, I would suggest a higher hiker to guide ratio - since we were required to carry our own gear to the high camp - and one of the members was not strong enough to pull their own weight - this added additional burden to the other climbers! I am so frustrated that due to the lack of training, responsibility, and knowledge of one climber it ruined the entire experience for the rest of us!


I recommend Gaston as an example of a first rate mountain guide. Very attentive to his clients and an excellent chef. I have never been so well looked after on an expedition. Thank you all very much.


The trip to Aconcagua with Gastón was really nice. Gaston was a great guide and we all learned a lot from him. In addition to his mountaineering skills he is an excellent story teller and we enjoyed his company a lot. It was unfortunate that we were not able to summit, but I was expecting that may be the case with weather so I was not disappointed. All in all, I was really pleased of the service, food, wine, company, mountain. I can not think of anything bad to say.


Gaston is the most experienced guide and trustworthy person that I've ever met in my life. We summited Aconcagua in 9 days and it was the best adventure in my life. Definitely recommend!
