MOUNTAIN guideS
our mountain guides
Our primary mountain guides get more than 10 years of experience in Carstensz Expedition, and have reached more than 25 summits escorting international groups.

They are also rock climbing instructors whose equipped by advanced mountain rescue skills. In addition, we have a second team of junior mountain guides who sometimes get involve as assistants at Base Camp.
As our support team, we have two technical & logistic support crews who settled in Bali & Timika for many years. They support all guest needs related to the Carstensz expedition.

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 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.
