Carstensz Pyramid, one of the least climbed of the “7 Summits” is a formidable objective located in Papua, Indonesia. Our expedition begins in the beautiful island of Bali, where we fly to Timika then onward to the Yellow Valley base camp. Our high-end logistics, local staff, and mountain guides ensure you are well taken care of throughout the expedition. The mountain is limestone that rises from the thick forest below, jutting to just over 16,000′. This rock climb requires basic rock climbing ability to mostly 5th class terrain on fixed ropes.

Note From Garrett: I am very excited to lead our trips to Carstensz Pyramid! This expedition will be a “fly in and fly out” as current circumstances in Western Papua necessitate air transport. Our recent expedition to Carstensz Pyramid utilized air transport and was very successful: click to read the expedition dispatches. I look forward to again repeating this high success and safety with you on our next adventure!

Helicopters: Using helicopters to fly in and out allows us the best chance for an overall successful expedition, reaching the summit and returning safely. Recent logistical difficulties have resulted in some climbers not reaching the mountain, as well as detainment by tribesmen and the security company overseeing the mining operation adjacent to the mountain. Until the last few years, trekking was the normal way to access the peak, with heavy reliance on local Dani Tribesman. Helicopter transport, in general, reduces the number of variables in reaching our destination. Utilizing the helicopter also reduces the chance of contracting an illness while trekking, avoids the local politics, and offers easy and reliable evacuation.
