K2 Flash™

Climb one of the most prestigious mountains in only 4 weeks: K2 8.611m, Pakistan.

Whilst a standard K2 expedition usually takes 8 weeks, on the Flash™ expedition we halve the duration through pre-acclimatisation at home in a hypoxia tent! This means that one of the most beautiful, challenging and prestigious mountains in the world can now finally be climbed in the tried-and-tested Flash™ style – with greater safety and a higher chance of success! Thanks to our hypoxia preparation, the K2 Flash™ expedition has already been completed by one participant in just 21 days, travelling from and to New York – and that was even without the need for additional bottled oxygen.

By acclimatising at home, we avoid having to make multiple ascents and descents on the objectively dangerous and technically challenging K2. As soon as the weather permits, we’ll set off on a direct summit attempt via the stunning standard route on the South-East Ridge (Abruzzensporn). Sherpas and high-altitude porters will accompany us. If we succeed, the absolute highlight of every mountaineer’s life awaits!

We will fly in our proven and experienced Sherpas from Nepal, who will support our Pakistani high altitude porters and insure the route. This is an additional safety factor.

Info for K2

We recommend oxygen for the summit day at the latest (this is included in the price). This means that the statistically most accident-prone passage under the Hängeserac after the shoulder and the bottleneck can be climbed much faster and safer both on the ascent and the descent. The fixed ropes in the summit area are only laid during the ascent to the summit. If you want to ascend without oxygen, you can do so, as long as you can prove that you have the appropriate experience and skills.

Registration for the K2 Flash™ expedition is subject to a personal consultation.

Preparation:

In order to enable an expedition in such a short time frame, appropriate preparation is vital. The preparation starts with an individual consultation talk, where goals and training topics are defined. Every member must have comprehensive mountain experience in high altitudes. Fitness and mental resilience must be trained intensively during the months prior to the expedition. Furthermore, we emphasize the importance of careful acclimatization. This will take place at the members home via hypoxic tents: every member will receive an individual training schedule and will be acclimatized in 6 weeks prior to the expedition.  As a result, most of the risky and exhausting acclimatization ascents can be skipped and the total duration of the expedition can be limited to 5 weeks. If you have any questions, read our FAQs or contact us directly.

The exact schedule on the expedition depends on regulatory requirements, the weather and snow conditions. In addition, keep in mind that we are in a very remote and politically sensitive area where our freedom of movement may be limited at any time due to governmental or environmental restrictions.

In addition to the basic framework which we provide, for example Sherpa support, base camp, route, high camp etc., a successful ascent also requires a great deal of luck, good weather, good physical condition and mental strength of the members. We allow maximum flexibility. The expedition can be extended if required by the circumstances, if the members wish to do so and are ready to bear the additional costs incurred.

The following schedule is planned:

Day 1 - 7: Arrival in Islamabad and spectacular hike to K2 basecamp

Day 1: Arrival in Islamabad, meeting point at the hotel in Islamabad.  Members have a day at leisure while the expedition leader handles last administrative things with the authorities.

Day 2:Either two days bus trip to Skardu with overnight stay in Chilas or a flight to Skardu, if the conditions allow it. The bus ride has it’s charm, leading through the varied landscapes of Pakistan to the Indus valley, where we take the legendary Karakorum Highway. On the second day shortly after Chilas views of Nanga Parbat with the Rhakiot flank mastered by Hermann Buhl. Overnight stay in a hotel in Skardu.

Day 3: We spend the day in the small but lively town of Skardu at 2.300m. The porters are organised, the luggage is loaded, final errands are run or a hike is undertaken.

Day 4-7: Shortest possible way from Skardu to the base camp via Gondogoro pass. This usually takes around 4 days. On the last day we arrive at the K2 basecamp at Godwin-Austen Glacier.

Day 8 - 22: K2 8.611m summit attempt

Day 8 – 22: Thanks to the pre-acclimatization at home we will only need around 2 weeks for our K2 ascent. First we refuel, organize material and might take a first acclimatization-rotation. Due to our pre-acclimatization at home, we have spared ourselves multiple ascents and descents passing the objectively dangerous and technically challenging sections, thus increasing the safety. Then we wait for a suitable weather window for a direct ascent attempt over the Abbruzzensporn with 4 high camps. Camp 1 at about 6.000m we reach relatively easy over a 40 gad steep firn flank. From there we go through snow gullies and combined terrain to the first key point, the approx. 25m high house chimney insured with fixed ropes. Shortly afterwards we reach camp 2 at 6.600m.
The further way to camp 3 depends strongly on the conditions. Snow flanks, rock passages and combined terrain with individual steep turns change until our southeast spur meets the east ridge (Black Pyramid). From here easier along the east ridge to camp 3 at 7.350m. The way from camp 3 to camp 4 at 7.900m on the shoulder is a technically easy snow ridge and ridge. In Camp 4 you see two things very prominent: the intoxicating panorama on one side and the dangerous Hängeserac with the infamous “Bottleneck” on the other side. This is the most dangerous part of the route.
The bottleneck is the key point for the next summit day and is secured with fixed ropes. From here on at the latest we use oxygen, which allows us to pass this dangerous passage faster and safer both in the ascent and in the descent. About 100m after the bottleneck, the terrain covers itself and the last meters lead over a simple snow slope to the summit. Should the weather allow it, we still have time for a second summit attempt. We recommend to book a rebookable return flight to be able to extend the expedition a few days if necessary or to travel home earlier if we can finish the expedition already earlier successfully.

Day 23 - 28: Return journey to Islamabad

Day 23-26: Dismantling of the base camp and return to Skardu via the Gondogoro Pass. Overnight in tent and hotel in Skardu.

Day 27: Skardu – Islamabad. Return to Islamabad. If possible with flight otherwise again the two-day bus ride. Overnight stay in a hotel in Islamabad.

Day 28: Individual return journey.

Why Flash™?

One of the main reasons for a failed climb of a high summit is the long acclimatization time at the mountain. The repeated ascents and descents, the threat of catching an infection at the base camp, where many people must live in a very crowded space, robs many climbers the energy even before the actual climb has started.

To raise the chances of success, we begin with the acclimatization process via hypoxic tents at the members’ home, 4-8 weeks prior to our actual departure to Pakistan. Those tents are going to be set up by our experts and under their supervision, the expedition members body will slowly be acclimatized to a height that is equivalent to around 7000m. Furtenbach Adventures is using hypoxic tents since almost two decades and we have a long experience with these means of acclimatization for high altitude mountaineering.

In 2016, our team was the first successful Everest expedition, where all members where pre-acclimatized with hypoxic tents. This decreased the time we had to acclimatize at the mountain significantly, before we could start our ascent to the summit. After reaching the summit, we were also the only team that was able to descend in one go to Camp 2. This higher performance capacity contributes largely to the safety aspect, thanks to proper pre-acclimatization.

These special preparations, combined with small groups, best oxygen-support, the latest equipment, an experienced team (some of our Sherpas have climbed Mount Everest up to 20 times) and our vast organizational experiences allow the total expedition duration to be shortened significantly. So far, we are the only operator at Broad Peak and K2 that can offer such a short period without increasing any risks.

Since decades, the fundamental techniques, equipment, high-altitude medicine and weather forecasts have been developed over time. The climbing tactics however have remained the same as they were in the 1970s. We are about to change that by providing a modern climbing alternative which meets the current state of the art and respects the general principles of safety.

info  General

Tour operator for this trip: Furtenbach Adventures.

An expedition to high altitudes still presents an enormous challenge despite modern equipment and tactics. Besides technical and fitness requirements, the high altitude still poses the largest hurdle. That is why we place great emphasis on prudent, slow acclimatization, and recommend our eight thousander expedition members the possibility of pre-acclimatization in a high altitude tent at home (see also FAQ).

Weather and conditions on the mountain can lead to program or route changes. Participation in the expedition lies in your own individual responsibility. Furtenbach Adventures assumes no liability for accidents, damages or loss of materials.

If you are not sure that taking part in an expedition like this is the right thing for you, feel free to contact us on Tel +43 512 204134 or e-mail [email protected] for a personal consultation.

This package in general is not suitable for persons with reduced mobility.

https  Insurance

We strongly recommend taking out a travel insurance (including trip cancellation, interruption, medical and luggage insurance) For this journey, the Global Rescue Signature Travel Insurance is suitable. The price of the insurance depends on the trip and the personal data of the traveller. We happily make you an offer after booking or upon request.

To cover search and rescue costs in the mountains, we ask our expedition members to take out a “medical only”-membership at Global Rescue. This membership can be concluded here before departure: https://ss.globalrescue.com/partner/furtenbach/. Further information are provided after your booking.

language  Entry requirements

EU or Swiss citizens:

Pakistan:

When entering the country, you need a passport with a validity of at least 6 more months. Each member must apply for the mountaineering visa early enough via the following website: https://visa.nadra.gov.pk.

All required documents will be sent and announced by Furtenbach Adventures well in advance. Information about recommended vaccines and health regulations: http://www.who.int/ith/en/

Travelers must be able to prove their return or onward ticket when entering the country. More detailed information regarding entry, visa and health requirements for this travel destination will be provided once you’ve communicated your nationality.

work   Equipment

Unless specified otherwise in the detailled program, all high camp equipment will be provided by us. You need to bring your own personal equipment such as down clothing, expedition shoes, an isolated sleeping mat and a down sleeping bag. Following your booking we will send you a detailed equipment list. We will be happy to advise you personally during the selection and purchase of required equipment. With years of expedition experience, we know what has proved its worth and what not.

insert_chart_outlined   Difficulty / Technique

The ascent always lies in the members personal responsibility, while led by the mountain guide and expedition leader. Members must be able to move safely and independently in mixed terrain (rock, snow, ice) and – if required – independently build rope teams under the guidance of the mountain guide. Cooperation, camaraderie and support on the mountain increases the chances of success for all. The guide is there to provide guidance for the whole group, the possibilities for him to respond to individual needs is limited. It is imperative that members adhere to the instructions and decisions made by the mountain guide. Regardless, each member must know their own physical limits, and be able to make a timely decision to turn back.

For expeditions offered by us, unless otherwise specified in the detailed program, the following is required of members: independent getting on and off the fixed ropes on cliffs, snow, ice and firn snow slopes, as well as the independent use of crampons and ice axes in mixed terrain. On climbing passages, as well as very dangerous and exposed places, fixed ropes are attached by mountain guides and by the Sherpa team.

perm_identity   Physical fitness

A key success factor in expeditions is being in good shape. Train in the months before the expedition! Several hour climbs with a backpack and around 1000 vertical meters per day should not be a problem for you. You have to carry your own personal equipment on the mountain, unless an optional personal Sherpa is booked. The porters are available for the group and set up the high camp and insure the route. We will gladly provide individual advice on how to best prepare yourself mentally and physically for an expedition!

local_hospital  Health

We recommend that each member undergoes a medical examination prior to the expedition. Good health is a prerequisite for participation. Particularly important is a visit to the dentist because previously unnoticed dental problems can become quite acute due to the sudden change in pressure conditions in higher altitudes.

landscape  Experience

We are very familiar with the charm and attraction of an eight-thousander! However, we want to make certain that you can ascend safely, come back alive, and be able to enjoy the expedition while on it and not afterwards. Therefore, in order to participate in our eight-thousander expeditions, you must already have collected some experience at high altitudes and mountaineering. When booking, please let us know which heights you have already reached and which high mountains you have climbed. If you are a newcomer, no problem, we offer a bespoke program aimed to train you for reaching your desired destination.

In order to participate in our seven-and six-thousander expeditions, you should have at least some experience on the four-thousander peaks of the Alps or other mountain ranges. Our offer for newcomers applies here as well, we can train you to become prudent and safe high altitude climbers!

We offer a special introductory weekend for all those who want to learn about – or refresh their knowledge of – all the skills and techniques needed on an expedition. More info here.

payment  Payment

Unless otherwise agreed, a deposit of 20% of the tour price is to be paid when receiving your invoice, but earliest eleven months before the end of the tour date. The balance must be paid 20 days prior to departure. Please find more information regarding payments in our GTC.
