Location and surroundings
Kosaraku belongs to the Bogosky Range, part of the North Eastern Caucasus in the Eastern Caucasus of the Greater Caucasus. It is in Dagestan, Russia, in Asia. Within the Bogosky Range it is the 5th highest of 133 named peaks, so it sits among the upper tier of the range rather than on its edge.
The mountain is surrounded by high ridges, passes and glacier terrain. The nearest settlement listed for the summit area is Likorotli, 5.1 km to the north. The landscape is typical high Caucasus ground: steep slopes, rocky crests, snow patches and glaciated approaches, with little in the way of easy low-level access close to the top.

Kosaraku is lower than Addala-Shukhgel’meer, the nearest higher peak, but it is higher than the nearby passes and several surrounding summits. The close spacing of 4,000-metre points means route-finding and ridge travel are part of the character of the area.
The view from the summit
From the summit, the highest nearby peaks within 25 km include Osuka to the west, Izhena to the northeast, Temirgokh to the southeast, Mal. Bochek to the west, Nogotl’ to the west and Zhekoda to the southwest. The nearest of these is Mal. Bochek, 2.7 km away, while Temirgokh is the farthest listed at 22.7 km.
The most prominent skyline feature in the immediate area is Addala-Shukhgel’meer, 1.8 km to the northeast and 4,152 m high. In clear weather, the summit outlook is likely to be dominated by neighbouring ridges, passes and the higher eastern Caucasus peaks rather than by distant lowland views.
The range
Kosaraku is part of the Bogosky Range, whose highest peak is Addala-Shukhgel’meer at 4,152 m, about 2 km to the northeast. The range contains 133 named peaks, and Kosaraku ranks 5th by elevation among them. That places it close to the top of the range’s height list, though not at the summit of the range itself.
The Bogosky Range lies within the broader Caucasus chain in Russia. Kosaraku’s position near the high end of the range, together with its short distance to the range high point, makes it part of a compact alpine cluster rather than an isolated mountain.
Climbing routes
The only listed route is the easiest line first: by the west ridge from the Belengi glacier, graded Russian 2A. It was first climbed in 1948. The route name points to a glacier approach and a ridge finish, so climbers should expect mixed alpine terrain rather than a simple walk-up.
With only one recorded route, Kosaraku is not a mountain with many options. A 2A route in the Russian system is a serious alpine outing that can involve snow, ice, rock and route-finding, and it is best suited to climbers comfortable with exposed mountain travel.
Access and starting points
The nearest settlement listed around the summit is Likorotli, 5.1 km to the north.
In this part of Dagestan, approach logistics can be affected by border-zone rules in valleys near the main Caucasus ridge. Travellers should plan the route in advance and check how to reach the relevant valley or start point before setting out.
Climate and weather
Climate estimates from NASA POWER data suggest that the summit is cold for most of the year. The warmest month is July, at about 3 °C, and the coldest is January, at about -14 °C. Mean temperatures above freezing are limited to July and August. Around the mountain, annual precipitation is about 500 mm, with the wettest month in May at about 70 mm and the driest in January at about 25 mm.
Typical hazards here include snow, ice, sudden weather changes, poor visibility and strong wind on ridges. Even in summer, the summit environment remains alpine, and wet snow or hard frozen surfaces can make the upper mountain more demanding than the elevation alone suggests.
Best time to visit
Because the summit is only above freezing on average in July and August, those are the most practical months for climbing. Earlier in the season, lingering snow and colder temperatures are likely to make the route more serious, while later in the year the mountain returns quickly to winter conditions.
The drier part of the year is not especially dry, but January is the driest month and May the wettest. For a climb, the usual aim would be the short summer window when snow conditions, daylight and temperatures are most workable.
Nature and wildlife
The mountain sits in a high Caucasus setting with rocky slopes, alpine grass, scree, snowfields and glacier terrain. At this elevation, vegetation is sparse near the summit and becomes more varied lower down, with alpine meadows and hardy mountain plants where the ground allows them.
Wildlife in the region can include mountain birds and mammals adapted to steep, cold terrain, but the upper slopes are mainly a place of rock, snow and wind.
Guides and organised ascents
For a 4,053 m Caucasus peak with a graded alpine route, a certified mountain guide is sensible unless you already have strong experience in glacier and ridge travel. In Russia, the national guide association is the Association of Mountain Guides of Russia (RMGA), which is not an IFMGA/UIAGM member. The national alpine club is the Russian Mountaineering Federation.
Visitors also commonly look to established guiding companies working in Russia, such as Alpindustria Tour in Moscow. A guided ascent usually depends on the number of days, group size, hut nights and equipment needs. Border-zone permits are required for valleys near the main Caucasus ridge, so permit checks should be part of the planning.
Safety and preparation
Kosaraku demands full mountain kit, fitness for steep alpine ground and the ability to move safely on snow, ice and rock. The west-ridge route from the Belengi glacier suggests crevassed or at least glacier-influenced terrain, so rope work, navigation and weather judgement matter. Even in summer, cold nights and rapid weather changes are normal at this height.
The emergency number in Russia is 112. Mountain rescue is handled by MChS (EMERCOM), and groups are advised to register their route with the local rescue unit before heading into the mountains.
Interesting facts
Kosaraku is the 5th highest of 133 named peaks in the Bogosky Range. Its nearest higher neighbour is Addala-Shukhgel’meer, only 1.8 km away to the northeast, and the range high point is 2 km away. That close spacing shows how tightly packed the high summits are in this part of the Caucasus.
The mountain’s only listed route was first climbed in 1948. Its summit area is also close to several passes, including Kosaraku Pass just 0.3 km away, which underlines how much of the local terrain is shaped by ridge crossings and high saddles.
FAQ
How high is Kosaraku? It rises to 4,053 m.
Where is Kosaraku? It is in Dagestan, Russia, in the Bogosky Range of the Greater Caucasus in Asia.
What is the nearest higher peak? Addala-Shukhgel’meer, 4,152 m, lies 1.8 km to the northeast.
How hard is it to climb Kosaraku? The easiest listed route is the west ridge from the Belengi glacier, graded Russian 2A. That means a proper alpine climb with ridge travel and likely snow or glacier sections; harder conditions would demand more experience with rope work and mountain navigation.
Are there huts on Kosaraku? OpenStreetMap shows no hut or shelter within 2 km of the top, so hikers usually plan the ascent as a day trip or carry their own tent.
Is there water on the way to Kosaraku? At this height, water is usually from snowmelt or glacier melt and should be treated before drinking. On dry ridges you need to carry your own supply; plan on about 1.5-3 litres for a day, depending on heat and route length.
Will my phone work on Kosaraku? Coverage in the hills is patchy and depends on the operator. 112 reaches emergency services over any available network, and maps should be downloaded before setting out.
