The adventure

An expedition to the remotest place on earth.

Extreme weather conditions, however, without great technical difficulties.

Stunning and unforgettable landscape.

Mount Vinson - one of the “Seven Summits“

Since 2000, Kobler & Partner has organised successful expeditions to Mount Vinson.

Kobler & Partner enjoys the coveted „Preferred Guiding Company“ status at ANI.

Antarctica is the most remote, coldest, driest, windiest and least developed continent in the world. It’s basically the most extreme of the seven contintents. The Antarctic continent covers a surface area of about 14 million square kilometres, which is approximately a tenth of the entire land mass of the earth. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness.

Mount Vinson (4,892 m) is the highest mountain of Antarctica making it one of the Seven Summits. Mount Vinson is located in the Sentinel Range which lies in the west of Antarctica. It has a northwest to southeast orientation, is about 185 km long and 50 km wide and is surrounded by massive glaciers. It is home to the five highest mountains of Antarctica. 

Mount Vinson was only discovered in January 1958 during a flight of the US-Air Force over the Sentinel Range. The first ascent followed eight years later on 17 December 1966 which makes Mount Vinson the last of the Seven Summits to be climbed.

The challenges of the ascent are not primarily due to technical difficulties, they are mainly due to the extreme cold and regular storms as well as its very remote location. The mountain it is only 1,200 km away from the South Pole.

The starting point for all expeditions is the Union Glacier Base Camp, which is about 80km away from the foot of the mountain. The camp is established every year for the Antarctica Season which only lasts four months. It is located approximately 3,030 km away from the South American continent and is located at the foot of the Siefker Ridge, a rutted, eleven-kilometres long mountain ridge.

Day 1 - Day 2: Flight to Punta Arenas

Flight via Santiago to Punta Arenas, the southernmost city of Chile. Depending on your connections, the flight from Europe to Punta Arenas takes between 24 and 30 hours.

The leading mountain guide will travel to Punta Arenas a few days beforehand to make all the necessary preparations and pick us up from the airport. The group will then drive together to a good and centrally located hotel in the southernmost city of Chile.

Day 3: Punta Arenas

Today we will do our last preparations as well as the expedition briefing, which will gear us up for the peculiarities of the flight to Antarctica. The briefing will give us enough information to make sure we know what to expect during our trip.

Day 4: Flight to Union Glacier

Finally the adventure begins! We board an Ilyushin plane that takes us to the Union Glacier Camp, which take about 5 hours. The flight and the ensuing landing on ice is unique and very spectacular.

The Union Glacier Camp is located at approximately 800 metres above sea level. The camp is one of three bases on Antarctica that are not located on the coast. The other two are the American Amundsen-Scott Station at the South Pole and the Russian Wostock Station at the cold pole. From this point, nighttime darkness will be a thing of the past as we are exposed to the eternal midnight sun!

Day 5: Union Glacier - Vinson Massif

From the Union Glacier Camp we continue our journey with a Twin Otter or Cessna to Vinson Base Camp at 2,134m. The flight, which offers a wonderful view of the entire Vinson Massif that sprawls over 13km, takes about 40 minutes.

Day 6 - Day 14: Mount Vinson

We will spend the following nine days to climb Mount Vinson. We need to establish two high camps. The first camp is at approximately 2,800 m, the second camp is at about 3,780 m - at least that’s the plan. The crux of the climb lies between the high camps, where we have to negotiate a pillar which is secured with fixed ropes.

During the entire ascent we are surrounded by the grandiose mountain scenery of the Ellsworth Mountains.If you haven’t noticed the uniqueness of this expedition by now, you will certainly do so during the ascent.

Depending on how many days we need, the return to the Glacier Union Base Camp can take place somewhat earlier or later.

Day 15: Flight to Punta Arenas

Today, we will return to civilisation. The Ilyushin takes us back to Punta Arenas. After all the hardships of the past few days, we will certainly enjoy the hotel and all its amenities.

Tonight’s dinner will be a feast!

Day 16 - Day 17: Punta Arenas (Spare Days)

The flight to and from the Union Glacier Camp depends on the weather, hence we have included some spare days in the itinerary

If the return flight from Antarctica to Punta Arenas takes place according to schedule, we have the option to go on many interesting excursions, like for example a visit to the nearby located penguinery or to the Paine National Park.

Day 18 - Day 19: Return Flight from Punta Arenas

The flight back home from Punta Arenas has to be undertaken individually. Our mountain guide stays behind in Punta Arenas in order to re-establish the equipment. On the 19th day we stand once again on familiar ground back home, with the knowledge that we have experienced something very special.

Important info

The Profilcheck is an integral part of our detailed expedition programme. Please read it thoroughly and assess your skills and physical condition.

The expedition is demanding and exhausting.

The members do not have to be “super alpinists”, however, they should have a certain amount of high altitude mountaineering experience. The members should be able to move in independent rope parties on the mountain. Active participation, camaraderie and tolerance are of great importance to us.

You have to be able to recognise your own limits on the mountain and be prepared to, if necessary, abandon the attempt and turn back. You join this expedition at your own responsibility.

The leader of the expedition is responsible for the management of the entire group, and personal support is not one of his/her responsibilities. Nevertheless, every member has to prepared to follow the decisions made by the expedition leader. The decisions are always made in the group’s interest.

Weather window

An expedition to Antarctica is something special. It is subject to certain rules as nowhere in the world are the climatic circumstances more extreme than there. For this reason, an itinerary only provides the outlines of a trip. Longer waiting times due to bad weather happen frequently which can put the patience of every individual to the test. Our 12-day-window (from/to Punto Arenas) gives us plenty of time to climb Mt. Vinson. If we decide to extend the expedition due to bad weather, problems with our transport, medical emergencies or other eventualities, the ensuing costs are to be coveredy by the members.


The Antarctic continent is a climatic extreme case in every possible way. It is not only the coldest but also the driest as well as the windiest corner of the world. The annual average temperature is -55°C. The monthly average temperatures vary quite a bit due to the length of the days. During the Polar Night in winter, the sun does not shine at all while during the Antarctic summer, the sun shines for 24 hours a day. The warmest months are December and January. At the time when our expedition takes place we have to expect temperatures of around -40°C. The average annual precipitation is around 40 l/m2 inland. According to precipitation oriented definitions, Antarctica is considered a desert - and not just any desert, but the biggest desert on earth! The South Pole position and the constant down draughts that blow from the Polar plateau to the coast do not only affect the continent but also the Antarctic Ocean: In July 1972, the Dumont d’Urveille Station measured a wind speed of 327 km/h (91 m/s).

First Come, First Fly

First come, first fly - this saying certainly proves right in Antarctica.
