Why Climb with Us

Why Climb Carstensz Pyramid with Alpine Ascents?

From our expertise gained from the world’s high mountain ranges, we have created a personalized and enjoyable approach to this popular trip. The familiarity with the region, combined with our expertise and knowledge around the world, lend a depth and richness to every expedition that we feel is unrivaled in the guiding community.

This departure employs the use of both helicopters and hiking with porters to reach base camp.

Risk Management

Your wellbeing on this expedition is a prime concern, and we therefore provide you with the best equipment available. All guides are well-versed in wilderness first-aid techniques. Ultimately your guide makes decisions with your comfort and wellbeing in mind, and yet tries to maximize your adventure. For your own wellbeing, it is important that you are comfortable with standard climbing techniques and climbing equipment.

The Carstensz Pyramid trek/climb was an absolutely wonderful adventure. The Adventure Indonesia guides were excellent. Our guide’s comfort and skill interacting with the porters allowed us to “share life” with the locals for a few weeks and enhanced our experience and understanding of the Papua people.
