Mount Elbrus is a dormant volcano located in the western Caucasus mountains, in Kabardino-Balkaria and Karachay–Cherkessia of Russia.
The ascent of Elbrus from the south takes about 6–9 hours, with a total height difference of 1700–2000 m (5718–6542 ft) between the Barrels Huts and the west summit of Elbrus. From Terskol village one can walk 5 km (3 miles) to the first elevation, Azau (2350 m/7700 ft). A cable car service is available from Azau to the normal starting location for the Elbrus climb, known as Barrels Hut or Garabashi Station .
The Normal Route is the easiest, safest and fastest on account of the cable car and chairlift system which operates from about 9 a.m. till 3 p.m. Starting for the summit at about 2 a.m. from the Diesel Hut or Leaprus mountain hut should allow just enough time to get back down to the chairlift if movement is efficient. A longer ascent Kiukurtliu Route starts from below the cable-way Mir station and heads west over glacier slopes towards the Khotiutau pass.
