Madison Mountaineering

Madison Mountaineering is a boutique mountain guide service specializing in organizing and leading climbing expeditions to the world’s most famous and formidable mountains: Mount Everest, K2, the Antarctic’s Mount Vinson, the “Seven Summits”, as well as unclimbed peaks in extremely remote regions.

Every year since 2014, we have led expeditions on all seven continents, including three of the highest mountains in the world. Detailed accounts of our most recent expeditions can be found in our Dispatches.

As a part of our guided climbs, Madison Mountaineering provides the education and training for climbers who aspire to become self-sufficient, aware and respectful of the local culture, stewards of the environment, and for whom safety is the number one priority in all climbing endeavors.

I was very lucky to be part of your team and under your leadership, Garrett!  It looked easy and fun because you were leading on all logistics. Management is everything!

Joyce Azzam, 2019 Mount Everest climber

You guys knocked it out of the park.  It was a 10.  Best expedition I’ve ever been on!

Jim Walker, 2019/2020 Mount Vinson climber

You run a first rate operation. There may be some (a few perhaps) that are as good in terms of staffing and experience, but there are none that are better and most are clearly inferior.

Art Muir, 2019 Everest climber

Every step of the way with you was remarkable. I couldn’t have enjoyed the experience more. You run a wonderful business with a world class team. It is only when you live it every day, and see the carnage that the alternatives can bring, that you fully appreciate how well we were all treated!

Michael Lavelle, 2019 Everest summiter

Thank you for a journey of a lifetime Garrett.  I had an absolute blast and I can finally say I climbed with Madison Mountaineering.  THE ONLY WAY TO GO 🙂

Mona Shahab, 2019 Everest summiter

The expedition was everything and more. The summit was great, but the team was the bonus — Garrett, man we got on so well. That made K2 for me. You selected well and were the perfect leader allowing us to be the mountaineers we are. Words won’t express my gratitude in the overall expedition.

Jason Black, 2018 K2 climber

Thank y’all for making it a trip of a lifetime. We will have to book another trip with y’all soon!!! Madison Mountaineering is a great group and very well run.

Jonathan Eakes, Mont Blanc / Matterhorn 2018

Absolutely the best prepared, most experienced, and safest guide company on Everest. Climbing Everest with Madison Mountaineering exceeded my expectations, I could not be more satisfied with my experience.

Jeffrey Glasbrenner, Everest 2016

I’ve climbed with a number of outfits throughout the years and Madison is hands down the best in all aspects. I have no need to work with anyone else in the future. Madison has an incredible success record because of the importance that they place on climber strength and teamwork. They employ the best guides

John Stenderup, Everest & Lhotse 2017

We had a great trip. Arrangements were great, we loved the safari, and the climb was amazing – I’ll happily recommend Madison Mountaineering to anyone who wants to climb Kilimanjaro.

David Thompson

On July 27, 2014, my birthday, I became the oldest American to summit K2. The professionalism and skill of Garrett Madison was key in this achievement. His attention to detail, plus leveraging his extensive Everest experience gave our team the best chance to summit and descend safely and quickly on arguably the world’s toughest mountain.

Alan Arnette, Fort Collins, CO

I had a magnificent time in Africa with Garrett Madison. Everything was first class. Garrett puts his climbers, at all times, first. Garrett always made sure I was taken care of. It was a fantastic experience.

Judge Mike Heavey (Ret.), Seattle, WA

Garrett / Madison Mountaineering is the most professional, organized, flexible and creative guide services I have used.  The preparation and dissemination of detail prior to climbs is exemplary, knowledge imparted while in the mountains superb, and memories created from these trips irreplaceable.

Scott Thomas, Seattle, WA

I’ve had the great fortune of climbing with Garrett on several expeditions. He is, quite frankly, the ultimate guide. His knowledge, skill set, temperament, and judgement are unparalleled.  Safety is key. After all, climbs only count if they are round trip.  And he makes it fun! I can’t imagine climbing without him.

Robin C. Houck, Bainbridge Island, WA

I’ve been very fortunate to have Garrett Madison as my guide on five high altitude climbs. As one of the top mountain guides in the world, Garrett possesses extraordinary expertise, athleticism, and passion for climbing. He not only keeps his clients safe, he ensures that they have a truly unforgettable and fun experience.

Jim C., Seattle, WA

Climbing Kilimanjaro was my first big mountain adventure. I had no idea how much fun and how rewarding it would be. All of the logistical details were handled by Garrett Madison and the program seemed very streamlined and well thought out. For climbers wanting a great program on Kilimanjaro I strongly recommend going with Garrett.

Gage Peterson, Seattle, WA

Thank you Garrett Madison for taking my family and I on an unforgettable adventure to Africa!  We wanted to climb Kilimanjaro and do a safari, but most of us had little or no hiking experience, nor had we traveled much outside of the US.  The experience greatly exceeded our expectations, and changed our lives forever.

John Rudolf, Bellevue, WA
