The Jayawijaya Mountains are located in the middle of Irian Jaya, in the Jayawijiya Regency. The highest peaks are
Trikora, Jaya (Carstensz Pyramid), Yamin and Mandala.
The Jaya peak is the most extreme mountain in the Jayawijaya region, and as the highest mountain in Australia and Oceania, one of the seven summits of the world. Some sources count the peak above 5,000m, but 4884m should be the truth. Climbing Jaya (Carstensz Pyramid) is an expedition and only suitable for experienced climbers. It is always covered with snow and you even find some small glacier.
Access to the Carstensz Pyramid is rather complex. Because of repeatedly emerging unrest in the indigenous population
of Papua, the access routes are sometimes changed. One must definitely count with some domestic flights in Indonesia
and expect then one week of jungle trekking until you reach the entrance to the mountain. The climb itself requires
several hours of enduring climbing (UIAA III-IV). Overall, this expedition is not to make less than 3 weeks.
The easier way of climbing a Jayawijaya mountain is Trikora peak, which is only a few meters lower than Jaya. However, the Trikora tour also is far away from simply mountain wandering. It's a difficult tour that requires very good physical condition and high mental capacity. Strong team skills and alpine experience is necessary.
Travel into the Jayawijaya Mountains
After some domestic flights that bring you into the Illaga valley, where porters can be recruited, you have two options. The first possibility to access the Jaya peak is one week of difficulty trekking through the jungle. However, with perfect acclimatization.
The second option is a helicopter trip directly into the base camp. However, due to complicated permits and registrations that are necessary to enter the region, and also because of the long lasting and complicated access to the peak, it is nearly impossible to make this tour on an individual basis on your own. We therefore strongly recommend taking an organized tour.
Access to the Trikora peak is much easier, as this is via the Baliem Valley.
