Climbing and traveling in Papua entails a great deal of uncertainty and requires tremendous flexibility. In addition to the fickle equatorial weather amplified by high altitudes, political and bureaucratic challenges exist and can hinder the progress of the expedition. For these reasons we build additional flexibility into our itinerary and request that all team members fully understand the nature of where we are going, and the unforeseeable changes to our day to day itinerary that may occur.
Carstensz is a relatively unvisited and remote climb, offering a truly unique journey from dense low jungle to high technical rock, snow and ice, as well as extraordinary cultural exchange with remote native tribes of Papua New Guinea.
Carstensz Pyramid summit day is a one day climb, necessitating a pre-dawn departure to avoid the afternoon equatorial precipitation. The climbing is a moderate technical challenge, involving mostly rock scrambling and a few sections of mid 5th class difficulty. Proficiency with fixed ropes, ascenders, rappelling, and experience rock climbing are required.
