I would highly recommend IMOSA as your only choice for guide service on Carstensz. The guide and staff go above and beyond to make sure all of your needs are met. You cannot beat their professionalism and knowledge on and in the mountain.
I had an incredible time on the mountain and our team had not only successful climb, but a safe one as well.

"I can highly recommend Imosa for your climb of Carstensz Pyramid. Imosa organized our climb with great attention to detail from beginning to end. The staff was a joy to be around, so efficient and caring in all aspects of our trip. The guide is a triple-A guide, a great vegetarian cook and made my climb a safe and very enjoyable summit, such a genuine guide and a pleasure to climb with. I would certainly choose Imosa for any future climbing trips in Indonesia".

Amazing trip to Carstensz. Imosa staff's took care of us from A-Z. Everything went perfectly according to plan. We summited on 21st of August. The guide did a great job taking me and my friend to the top. We couldn't have asked for better guiding. And thanks for his patience.
The staff in Timika was just amazing at taking care of us outside the mountain. Whether it was to organize tickets or pick ups or the helicopter, everything was handled with super professionalism.
We made 2 great friends in Papua. Thanks Imosa...

IMOSA did an amazing job for Purple Heart Summits and American 300. They were the critical link for our team in getting Benjamin to the summit of Carstensz Pyramid. They took care of everything from the airport to the Summit.


The team is professional and experienced in leading in the mountains. If you are going to climb Carstensz Pyramid go local and go with Indonesia Mountain Specialists.

Thank you IMOSA for making our Carstensz trip successful. The staff in Timika was super helpful making sure all the logistics were taken care of. Even helping change our flights at the last minute. 


The mountain guide made us comfortable at basecamp. He cooked great meals and was the perfect guide on the mountain.


Imosa runs well-organized trips. The tents were perfect and comfortable.
