The epitome of a challenge, scaling Mount Everest is a serious achievement even for a seasoned mountaineer. Granting access to quite literally the top of the world, the mountain stands at almost 30,000ft above sea level, famously making it the highest peak on earth. Usually, an expedition would take nine weeks or more, but Furtenbach Adventures’ ‘flash’ Everest expedition takes less than four weeks, thanks to at-home acclimatization using hypoxic tents. For those who have the financial means to conquer Everest (the permit, gear and guides alone cost around $50,000) but not the time, this experience is the solution. In addition to the pre-acclimatization, maximum oxygen support is granted during the ascent, as well as the latest equipment, expert guides and experienced sherpas. The spring 2018 expedition sold out within a few months, but bookings are now open for 2019.
