Carstensz Pyramid Trek and Climb - 20 days/19 nights


Carstensz Pyramid is also known locally as Puncak Jaya. Located on the Indonesia part of the island of New Guinea, it is considered the highest mountain of the Australia/Oceania continent. It’s the lowest of the “7 Summits” at 16,024 feet (4,884 meters) but it’s the only one that is a long, technical rock climb.

It was first climbed by Heinrich Harrer in 1962, who wrote his book, I Come from the Stone Age, about his 6-month expedition to climb Carstensz Pyramid and explore other areas of the region. Yes, that’s the same Heinrich Harrer that was the first person to climb the North Face of the Eiger and wrote the book: Seven Years in Tibet.

The route heads up a steep granite wall with sharp, good climbable rock up to low-to-mid 5th class difficulty. Only a few hundred people have climbed Carstensz due to occasional political instability and the fact that it is surrounded by dense jungle.

These days, most climbers take a helicopter into and out of basecamp to make a quick, but expensive, trip of it. However, our plan is to follow in Heinrich Harrer’s footsteps and trek for 5 days from Ilaga to basecamp and back again.

The expedition will start and end in Bali and last for 20 days:

Start Date: November 6, 2022

End Date: November 25, 2022

We’ll be led by the founder of Red Lantern Journeys, Ambrose Bittner, and the incomparable Dr. Werner Weiglein, who due to his longstanding relationship with the local tribes, is probably the only western person who can currently navigate the maze of permits and logistics to arrange this trek…and has done it for many years.

The trek is long and arduous through varied terrain and along muddy trails due to daily afternoon rain showers. You’ll want to be in your best physical condition for this trek and have at least basic rock-climbing skills for the mountain.

From basecamp, the mountain itself is climbed in a long day with much 3rd and 4th-class scrambling and rock climbing up to mid-5th class. The weather is typically good in the morning, but rains (or perhaps snow near the summit) start in the afternoon. The weather could be good until the descent, but be prepared to climb in snow and rain, with your leather gloves being torn by the sharp rock. You may also get a view into the nearby Grasberg mine–the largest open pit goldmine in the world!

This expedition will truly be a once-in-a-lifetime adventure.

Carstensz Pyramid Trek and Climb - 20 days/19 nights


The itinerary starts in Bali where you’ll be picked up at the airport and transferred to the hotel. We’ll collect passports and scan them in order to apply for the permits needed for this expedition. After one night and a free day to explore Bali, we take a midnight flight to Timika on the island of New Guinea, arriving early morning. There, we’ll spend time at the immigration office and the national park office signing documents and getting our permits. Finally, we separate our luggage into trekking and basecamp bags, then take a chartered flight to Ilaga where we show all of our permits at the police and military stations and spend our first night in a tent on the outskirts of a local Papua village. The basecamp bags will be flown to basecamp by helicopter.

The trek into basecamp is four and a half days of walking over rough terrain while slowly gaining elevation. The weather will be variable, but it will definitely rain, usually in the afternoon. The trails will always be muddy, but the terrain will be unique and interesting.

We’ll spend 3 days in basecamp. Day 1 to rest or explore the area. Day 2 to climb Carstensz Pyramid. Day 3 to rest or climb nearby peaks or make a second attempt at Carstensz Pyramid.

Then we’ll reverse the trek. If we’re feeling fit, we may be able to do it in one less day, but we’ll allow for 5. Back at Ilaga, you’ll have a chance to wash up in the river. Spend one night in Ilaga, then the following day take the charter flight back to Timika. Spend one night there, then take the domestic flight back to Bali.
