Possibly the most exotic mountaineering location on earth, Carstensz Pyramid in Western Papua (formally known as Irian Jaya) and is a large limestone escarpment jutting out above the rainforest. Coveted as the highest peak in Australasia, Carstensz is one of the most remote of the seven summits. The mountain was first climbed in the 1960s by an expedition led by Heinrich Harrer of Eiger North Wall fame yet factors such as intricate permit requirements and conflicts in the region have led to Carstensz Pyramid not receiving many ascents.

We have operated eight previous expeditions to the mountain. The trek to the basecamp at 4,200m starts after a plane ride to the island of Papua followed by another small plane ride to a remote village called Sugapa. It usually takes four days trekking to reach basecamp. We ascend the mountain by the North Face in a long day from base camp. The ascent involves a combination of scrambling and climbing fixed ropes, suitable for climbers with recent rope and rock climbing experience.

History
Carstensz Toppen, or Carrstensz Pyramid, is a Dutch name, deriving from the 1623 voyage of exploration undertaken by the Dutch Empire as they strove to rule the lucrative trade routes of the East Indes. The navigator, Jan Carstensz, recorded his surprised sightings of ice-covered mountains soaring high above the Arafura Sea.
In 1872 Captain J.A. Lawson led an exploratory expedition inland, reporting an ascent to 7500 metres on a Mount Hercules! This sparked rumours that Carstensz was higher than the recently surveyed Mt Everest.
Ensuing Dutch and English expeditions failed to climb this legendary peak, but confirmed extensive glaciation in mountains so close to the equator.
The New Zealand expedition led by Philip Temple in 1961 finally got to the base of Carstensz Pyramid after an epic trek through the jungle but was forced to retreat after a failed airdrop of supplies. The following year Temple was asked to guide Heinrich Harrer over New Zealand Pass, the key to reaching Carstensz. Harrer and Temple then pioneered the steep rock climbing route to the summit. The pair went on to make ascents of many other peaks in the region.
In recent years, Carstensz Pyramid has become regarded as the highest peak on the continental landmass known as Australasia and thus one of the coveted Seven Summits.
