From Home to Everest in only 3 weeks? Furtenbach Adventures makes it possible.
Acclimatization for this expedition is already done at home. While a traditional Everest expedition takes two months, our Flash™ Expedition saves time and additionally increases safety and chances of success. (3 weeks only)

Our Flash™ Expeditions will fundamentally change the world of high-altitude mountaineering! The high risk of illness due to infections caught in basecamp is minimized as less time is spent in basecamp. Further, acclimatization is already done at home and on Island Peak, which saves us all of the acclimatization rotations on Everest. This results in the Flash™ expedition being more energy saving and therefore much safer due to fitter participants and fewer traverses of the Khumbu Icefall.

To maximise chances of success, the participants of the expedition sleep in a hypoxia tent for 6-8 weeks before the start of the journey, in which the body is getting acclimatized to an altitude equivalent of 7000m.

Furtenbach Adventures has more than 15 years experience in the use of hypoxia systems for pre-acclimatization in high-altitude mountaineering. Once in the Himalayas participants are acclimatized within a very short time and have a much higher efficency – Ready for the summit ascent! No other tour operator has as much experience and expertise with hypoxia systems for pre-acclimatization.

This innovative pre-acclimatization, combined with a small group, maximum oxygen support, best equipment and an experienced team makes the Flash™ Expedition so successful and allows an ascent within only 3 weeks.
Furtenbach Adventures is the only tour operator achieving such a short expedition duration besides minimising risk. Through our state-of-the-art expedition preparation we change the world of high-altitude mountaineering.

The Everest Flash™ Expedition is now also offered on the south side at the same time as Evererst North Flash™ Expedition. For preparation and acclimatization purposes the participants summit Island Peak (6189m) before reaching Mount Everest basecamp. The sherpas set up the high camps and oxygen depots in advance. As soon as the weather window fits, the summit ascent can begin.

Summit Oxygen is the latest, lightest and most reliable oxygen system. Our participants recieve special regulators that were developed just for us and deliver more oxygen than conventional regulators. This alows flow rates up to 8L / minute. Oxygen is available to all participants from Camp 2 (6400m).

The entire oxygen system is carried completley redudantly for each participant and deposited on the mountain. For each participants we hire at least 2 Sherpas, in order to be able to compensate defaults and transport the high amount of oxygen.

Day 1-8: Kathmandu and journey to Everest Basecamp
DAY 1: Arrival and get-together at the hotel in Kathmandu. Meet and greet the other climbers while enjoying a beer in the hotel gardens. A great adventure awaits us, and our journey is soon to begin. You can feel the anticipation, excitement and joy. DAY 2: Helicopter flight to Syangboche above Namche and overnight stay in nearby Khumjung at app. 3750m. During the flight we are surrounded by the impressive rocky mountains of the Himalaya. DAY 3-8: Acclimatization at Mera Peak. Trekking to and ascent of Mera Peak.
Day 9-21: Mount Everest Base Camp and summit attempt
DAY 9: Trek to Everest Base Camp (5330m), from where we will prepare and plan the ascent of Mount Everest. DAY 10-21: Within these days we will reach the summit of Mount Everest. The advantage is that we have only have to climb through the Khumbu Icefall once during the ascent and descent, as we already have acclimatized to a six-thousand metre peak and therefore do not need any further acclimatization rotations. We wait for the right weather window for our first summit attempt. From Basecamp we will climb to Camp 1 and further on to Camp 2. From Camp 2 (6400m) we have Oxygen at our disposal. In Camp 3 (7160m) and 4 (8000m) we can also sleep with oxygen. There is enough time for rest days and a second summit attempt.
