A standard expedition takes 12 days including the acclimatization and resting days before the final push. Moreover, you need to get used to the frigid cold and prepare the mind for the toughest next days of climbing to the peak. Lenin peak demands a certain level of fitness, basic mountaineering skills, prior experience at high altitude and certainly the desire to reach a peak of 7000 meters. If you have never been to mountains before, you should start from lower mountains, for example, from Elbrus, Kazbek or Kilimanjaro, to find out how your body will react to high altitude conditions, then test yourself at altitudes of 6000-6500 meters. Note that staying in the mountains can be life-threatening if you do not have enough experience or the equipment and hence it is better to use the services of local guides and travel agencies. 

Many travel agencies offer several packages to Lenin peak. For instance, packages may include transfer from Osh to the Achik-Tash camp, taking care of paperwork for staying in the border zone and several days in the camps for acclimatization. The option to go independently is much cheaper, but it has its disadvantages, firstly obviously the lack of an experienced guide who can save your life in case of a dangerous situation. 

In fact we do not recommend anyone to try to reach the peak without experienced company and adequate previous experience in mountaineering!
