Porters are workers with experience in mountain activities who play an important role in the development and success of all expeditions. Their task is the portage of expedition loads to high altitude camps. Porters go along the same routes that expeditionaries explore, but walking ahead of them.

Their work involves a great physical demand and mental resistance, and also requires experience, equipment and knowledge to perform on a regular basis in potential risk situations inherent to the mountains.

Expeditionaries need to save energies and focus on their expedition. Therefore, the logistical support of porters is crucial, since they are in charge of the careful portage of loads and the logistics involved in the ascent while expeditionaries accomplish their goal.
