2026 Carstensz Pyramid expedition dispatches

Summit photo atop Carstensz Pyramid!

And just like that! We are happy to report the summit success of our entire Carstensz Pyramid team on the morning of June 16. After crawling out of their sleeping bags, gearing up, and leaving their tent walls, clear and starry skies shined overhead. Climbers scarfed down some food and coffee to fuel up for the climb ahead, before shouldering their packs and starting up the route. We enjoyed excellent climbing and conditions through the night and into the morning, making great time while climbing higher up the mountain. There were some of the best views and climbing conditions we’ve ever experienced on Carstensz, with views as far as the eye can see and the mountain entirely to ourselves; not another soul was up there! The team celebrated together on the summit before descending back down to camp, safe and sound. What a day, and what an expedition it’s been so far! Expedition leader, Terray Sylvester checks in from the Yellow Valley Base Camp after successfully topping out on Oceania’s highest peak, Carstensz Pyramid:

Hello! This is Terray calling in for the Madison Mountaineering Carstensz Pyramid (4884m/16,024ft) Expedition. Today’s June 16th.

This morning, we left base camp (4285m/14,050ft) under perfectly clear, starry skies at about 5 a.m. By four hours later, the entire team was standing on the summit of Carstensz Pyramid, the highest point in Oceania, and one of the ‘seven summits!’ We had a really nice climb. The weather was perfect. We had perfectly clear skies as the sun rose over the Sudirman Range, which is just a really beautiful, kind of magnificent range with lots of exposed limestone, craggy peaks. And as we gained the summit ridge, we had clear skies looking down to the south as well, toward the Arafura Sea. I felt like if we’d been able to see just a little bit farther, we would have caught a glimpse of Australia! Really nice weather for Carstensz Pyramid.

Yeah, the clear skies and good weather continued all the way to the summit and back down. We are all back in base camp now and relaxing in t-shirts and shorts in the sunshine, and preparing for our flight back to Timika (31m/103ft).

All in all this expedition has gone really well so far! We arrived in Timika on schedule, flew to the mountain on schedule, summited on the day we planned to, according to our itinerary, the next day, and hopefully we’ll fly out of base camp later today or tomorrow. So, yeah, really special expedition here in the New Guinea Highlands.

This was a custom itinerary. So we are climbing outside of the usual seasons on Carstensz Pyramid, which means that we have the mountain all to ourselves. There’s no one else in base camp, just our little team, and we were the only ones on the mountain. Felt very peaceful, really special.

So yeah, all good here in the tropics in Papua. And we’ll be in touch tomorrow.

The Madison Mountaineering Carstensz Pyramid Expedition team reached their base camp today, tucked into the Yellow Valley at the foot of the peak. The flight into base camp is an exciting one, which we carried throughout the day. After settling into their tents, the team took to the lower section of the route for some technical skills review and acclimatization. Everyone did great! It won’t be long now before we start out on the summit push. Expedition leader, Terray Sylvester checks in with this dispatch from Carstensz Pyramid:

Hello! This is Terray calling in for the Madison Mountaineering Carstensz Pyramid (4884m/16,024ft) Expedition. Today is June 15.

Today we woke up early, headed over to the airport in Timika (31m/103ft), and the weather cleared! We were able to fly to base camp (4285m/14,050ft). So our entire team is now up at base camp, which is fantastic. It’s common for there to be some delays, because the weather in Papua is so wet and variable. But yeah, we had really good conditions and it’s fantastic to be here!

We spent the morning relaxing, and then this afternoon we headed up to the first, the “first terrace,” as it’s called. The first of three major ledges, on the lower portion of the route, just to get acquainted with the climbing on the lower route before we do it in the dark during our alpine start, and to stretch our legs and get a little bit of an activity to help us acclimatize now that we’re at 14,000 feet.

So, uh, yeah, we had really good foray on the route, rappelled back down to base camp, and now we’re just waiting for dinner. Dinner will be tuna steaks, and chicken wings, salad, french fries. Should be really good!

Yeah, it’s a beautiful evening here; calm with some mist drifting through the Yellow Valley. We’re really looking forward to making our first attempt at the summit tomorrow, if the weather cooperates. So we’ll be in touch tomorrow!

We’re thrilled to be back on Carstensz Pyramid with a strong team of climbers this June! The Madison Mountaineering team arrived in Timika over the weekend and look forward to their move up to the mountain soon. Our staff have been hard at work setting up base camp and are excited to welcome the rest of our guides and climbers tomorrow! With good weather, helicopters will take us over the lush jungle below, to the foot of Carstensz Pyramid, the highest peak in Oceania and one of the famed seven summits. Expedition leader, Terray Sylvester checks in with this dispatch from Timika:

Hello! This is Terray calling in for the June Madison Mountaineering Carstensz Pyramid  (4884m/16,024ft) Expedition. Today is June 14th.

Our guests all arrived in Timika (31m/103ft) today and we just wrapped up dinner at our hotel. We’re looking forward to flying to the mountain tomorrow morning, weather permitting.

Our staff all flew up there today. They’ve got base camp (4285m/14,050ft) all set up in the Yellow Valley at the base of the highest peak in Oceania, at about 14,000 feet. And the forecast is looking promising for tomorrow, so we’re hoping that we’ll head up to the mountain and be able to get started with the climbing portion of the expedition.

It’s a relatively beautiful day here in Papua. Had a little bit of rain in the morning. But otherwise, it was sunny, wonderful day here in one of the lushest rainforests on the planet. We’ll be in touch tomorrow.

Landing in the Yellow Valley Base Camp

The Madison Mountaineering Carstensz Pyramid expedition team is making moves up to the Yellow Valley Base Camp at the foot of the peak! Those that were able to fly enjoyed a spectacular flight before touching down in camp, settling in, and then going out for some training. The rest of the team is awaiting their flight in Timika, with hopes that they’ll be able to fly and come together again tomorrow! Expedition leader, Garrett Madison checks in with this dispatch from Timika:

Hey! This is Garrett checking in for the Madison Mountaineering Carstensz Pyramid (4884m/16,024ft) expedition, first one of 2026.

Well, today was a good day! We got two helicopter loads of our climbers and gear into base camp (4285m/14,050ft). And doing some training and getting ready for the summit attempt. We’re going to acclimatize probably a day or so up here at base camp.

The rest of us are still down in Timika (31m/103ft), hoping to fly in tomorrow. Fingers crossed for good weather, and we’ll all be up there soon! Alright.

Beautiful flight up from Timika to base camp!

March, 2026 Carstensz Pyramid expedition team

Here we go! Another Madison Mountaineering Carstensz Pyramid expedition has gotten underway in Bali. Not a bad place to start a climbing expedition if you ask us! The team gathered together, conducted a gear check, orientation and welcome dinner before setting off as they continue their journey to the highest peak in Oceania, and one of the famed ‘seven summits‘. The team is en route to Timika where they’ll then wait for their helicopter flight up to the Yellow Valley Base Camp. More to come! Expedition leader, Garrett Madison checked in with this dispatch from Indonesia:

Hello! This is Garrett checking in for the Madison Mountaineering Carstensz Pyramid (4884m/16,024ft) expedition – our first of 2026.

Our team has assembled in Bali, Indonesia (0m/0ft); beautiful paradise to begin the climbing expedition. And we are now en route to Papua, in Timika (31m/103ft), where we will meet up with our local outfitter and spend a day or two before hopefully, helicoptering up to the Yellow Valley Base Camp (4285m/14,050ft)!

All six climbers, plus myself, arrived with all of our gear. We’re happy to be here and looking forward to the experience. Hopefully we’ll have some good weather and conditions ahead! We’ll check in soon.
