San Lorenzo

San Lorenzo (3706 mts) is the second Patagonian highest mountain as well as one of the mythic peaks in the area. Its location near the northern Ice Field and its spectacular glaciers invite to a great non technical ascent but with some ice climb sections and glacier traverse with beautiful crevasses on the approach.

It is vital for each participant to check all his/her equipment properly before traveling. Said equipment must be in good conditions, it must be comfortable and of course, it must be apt for the purpose. If at half the traverse, any element of the equipment fails, we will not be able to go on normally or of course replace it.
As for clothes, we always recommend synthetic ones, especially for the inner ones and the torso ones: if you wear sweated cotton t-shirt, you will suffer cold very much until our body helps it dry.
