The ascent of Elbrus from the south takes about 6–9 hours, with a total height difference of 1,700–2,000 m (5,600–6,600 ft) between the Barrels Huts and the west summit of Elbrus. From Terskol village one can walk 5 km (3. 1 mi) to the first elevation, Azau (2,350 m; 7,710 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 (3,720 m; 12,200 ft). The next destination – the Diesel Hut at 4,050 m (13,290 ft) – is located south from the Barrels Huts and up the slopes of Elbrus. From the Diesel Hut the route heads straight up towards the east summit of Elbrus, continuing south up the slopes. The slopes surrounding the classical route to Elbrus from the South contain large crevasses. Heading towards Pashtuhova Rocks (at 4,550–4,700 m (14,930–15,420 ft) elevation), the classical route up Elbrus becomes steeper after passing between two linear rock bands. After leaving this section, the Elbrus route heads on – first northward, to the east summit of Elbrus, or rather the saddle between the east and west summits of Elbrus (5,416 m; 17,769 ft), but soon turns left to the west summit (5,642 m; 18,510 ft). Before reaching this saddle, the route passes through a gently sloped basin filled with snow. At the saddle there is a shelter, from which the route heads west, then – left, in the direction of rocks forming the shoulder of the west summit, in the form of a narrow, exposed snow path that allows for a straight dash to the summit ridge.
