At a glance
Trip overview
We organize and lead expeditions to Carstensz Pyramid, also known locally as Puncak Jaya, standing at 4,884 m in the remote highlands of Indonesian New Guinea. As the highest island peak on Earth and a member of the Seven Summits, this mountain presents a distinct set of obstacles that differ significantly from standard snow and ice routes. While the altitude sits below the death zone, the technical difficulty of the limestone rock and the remote jungle logistics demand absolute proficiency in rock climbing and rope work.
This 12-day itinerary is designed for experienced mountaineers who have completed significant high-altitude ascents and possess solid rock scrambling and ascending skills. We manage all operational complexities, from acquiring necessary government permits in Indonesia to establishing secure basecamps and coordinating helicopter support. Our lead guides maintain strict safety margins and provide hands-on instruction through the technical sections of the route.
Weather in the Papuan highlands is notoriously unpredictable, requiring flexibility and robust contingency planning. Rain, mist, and sudden squalls are common on the limestone ridges. We build contingency days into our schedule to maximize our summit window and ensure we do not compromise safety for speed.

Before you go
Good to know
Technical Requirements
Carstensz Pyramid is primarily a rock-climbing objective rather than a standard glacier walk. You must be entirely comfortable ascending and descending steep limestone on fixed ropes using ascenders and descenders.
Prior multi-pitch rock climbing experience and a high level of agility on rough, abrasive stone are mandatory for joining this expedition.
Weather & Logistics
The mountains of Papua experience heavy rainfall and erratic weather patterns throughout the year. Helicopter flights depend entirely on cloud ceilings and visibility, which can occasionally cause short-notice schedule changes.
We advise all participants to build flexible international flight connections to absorb any potential transit delays.
Permits & Bureaucracy
Securing authorization to enter the mining region and climb in Papua requires extensive government paperwork coordinated well in advance. We handle all local police, regional, and national permit acquisitions on your behalf.
Insurance & Evacuation
High-altitude rescue insurance that explicitly covers helicopter evacuation up to 5,000 m and technical mountaineering activities is compulsory. You must provide policy details prior to departure.
