Join us for a double header on Mount Everest and Mount Lhotse! Back in 2011, Garrett Madison helped pioneer this 'twofer' and has repeated it 5 times since, along with many climbers and guides on our teams. Reaching the summit on two of the 8000 meter peaks within a day is a huge accomplishment, an incredible way to experience climbing a second 8000 meter mountain after having climbed Everest. By combining these two peaks into one expedition, you save big on expedition costs and time compared to doing these as separate expeditions. You are also well acclimated and tuned up for high altitude climbing, generally doing the Lhotse summit after Everest is manageable for our climbers. It's a fantastic view gazing back upon Everest from the summit of Lhotse, the world's 4th highest peak, and a grand accomplishment!

You might also want to consider these similar expeditions: Our Expedition Leader: As Expedition Leader and Guide for 13 years running on Mount Everest, Garrett Madison has overseen all aspects for his teams related to planning, organization, and climbing on Mount Everest. As one of the best known “Expedition Leaders” on Mount Everest with the highest success and safety record in recent years, Garrett has personally accompanied over 70 climbers (clients) up Mount Everest to the summit since 2009 (as well as many co guides and climbing Sherpas), more than any other guide or Expedition Leader. Garrett is known for ‘climber care,’ making the well-being of his clients his number one priority, this is perhaps the most important differentiating factor in our expeditions compared to the others on Mount Everest. Garrett has recently climbed Mount Lhotse (4th highest mountain) three times, in guiding climbers on the “peak to peak” combination where members climb Mount Lhotse the day after reaching the top of Mount Everest. Garrett has been part of many “firsts” on Everest, such as the 2016 first ascent by an American with a prosthetic leg; however, his proudest accomplishment is a 100% safety record for clients under his watch while climbing the peak.

Our Everest Guides: After his 14th expedition to Mount Everest (the last ten years as ‘Expedition Leader’), Garrett Madison has reached the top 12 times. Garrett has personally guided more climbers (70+) over the last ten years than any other mountain guide or Expedition Leader. Our Everest guide team includes very experienced mountain guides with multiple Everest summits such as Brent Bishop, Conan Bliss, Billy Nugent, Stuart Robertson, Geoff Schellens, Fred Alldredge, Kenton Cool, and Sid Pattison, some of the most experienced and capable Everest guides on the mountain. This vast amount of organizational and logistical expertise, combined with a commitment to provide the best possible services to ensure safety and success, make Madison Mountaineering the premier boutique guiding company on Mount Everest. Climbers will have an unparalleled opportunity for safely climbing to the summit and returning to base camp, as well as climbing Lhotse if desired. Enjoying the experience is a high priority, and our climbers can attest to having a great time throughout! (Please contact us for past Everest climber testimonials)

Our teams are different than the large scale operations where climbers are locked into specific dates for rotations and summit attempts and maybe one of many people sitting down to eat in the dining tent, dealing with illness spreading throughout the group. Often these sprawling groups have only a leader who remains in base camp and coaches members over the radio, with our team your leader climbs with you to the summit and back, often making the crucial ‘mission critical’ decisions on the spot, this is a big part of our high level of success and safety. By keeping our team small yet highly supported, we don’t compromise our standards in providing the best strategy, flexibility, and resources needed to succeed in the dynamic environment that is Everest. The equation for success and safety involves variables that can and often rapidly change such as: mountain weather (wind speed, precipitation, temperature), climber acclimatization and health, climbing route (the route often varies daily through the Khumbu Icefall), other climbers and teams (climbers needing assistance, evacuation, as well as periodic overcrowding on the route).

We can quickly adjust to changing conditions better than any other team. We have the best communication systems available to monitor the weather (along with a few dedicated meteorologists), to communicate with other teams on the mountain to collaborate on the route, weather, rescues, and summit schedule. We have an experienced base camp manager, a menu plan developed by a certified nutritionist, and a helicopter available that can evacuate an injured or ill climber if necessary from as high as Camp 3. Our Sherpas are among the finest and most respected on the mountain, as evidenced by our Sherpas, who took part in fixing the ropes to the summit on May 15th, 2017, on May 14, 2018, and May 15th, 2019. Our team oversaw the 'rope fixing' project on Mount Everest for the last two years. We are a team that works together to accomplish our shared goals of safety, success, and having fun. If you would like to know more, we invite you to contact us!

Mount Everest is a harsh environment. We take pride in creating a team that can not only reach the top but can also get down safely, and survive. We are one of the few teams that have the ability to support climbers in distress who are high on Everest, commonly called the ‘death zone’ which is above 8000 meters. In both 2016 and 2017, our team provided medical support at Camp 4, the South Col, and contributed to the ultimate survival of other climbers.
