Climb of the volcano Kluchevskaya Sopka is not particularly  difficult technically - the complexity of the program is different. This hard and challeging, climb of Kluchevskaya sopka can be compared to climbing of seventhousanders - extremely hard and long ascent, inability to get a preliminary acclimatization - these factors are the main challenges for the ascension of Kluchevskaya Sopka. In addition, it should be remembered that Kluchevskaya Sopka - is an active volcano, which erupted constantly - in the scientific sense of that - only lava flows from it not every year. In that too, there is a certain specifics of the program - in the event of an unforeseen increase the activity of volcano climbing may not take place for objective reasons. There were cases when the climbing of Kluchevskaya was not possible even in the case of a small activation of volcanic processes - temperature of the cone of volcano rises and because of that begins a continuous rockfall. In other words, getting ready for the ascent to Kluchevskaya Sopka, we must be prepared for any eventuality - that's Kamchatka.
