Location and surroundings
Yarlu belongs to the broad chain of the South Siberian Mountains, within the Altai-Sayan Region, the Altai Mountains, Northern Altai, Northwestern Altai, and finally the Katun Range. It is in Russia, in the Altai Republic, inside Katandinskoye rural settlement and Ust-Koksinsky Rayon. In the Katun Range it ranks 19th by elevation among 34 named peaks.
The mountain rises in a high, rugged alpine landscape with nearby passes and summits close together. The area around the top is within the Golden Mountains of Altai and Prirodnyy park <<Belukha>>, so the surroundings are part of a protected mountain environment rather than a settled valley floor.

The nearest higher peak is Hora Járy Cimrmana, only 2.3 km away to the southeast. Several other summits and passes lie within a few kilometres, so Yarlu sits in a compact high-mountain cluster rather than standing alone.
The view from the summit
From the summit, the main high points within 25 km are part of the same alpine core of the Katun Range. To the south lies Belukha at 4,509 m, 10.1 km away, the highest peak in the range. Also in view are Korona Altaya at 4,178 m, 9.8 km south; CPSU's 50th Anniversary at 3,972 m, 12.3 km southeast; Mushtu-Airy at 3,750 m, 12.9 km south; Tomskikh Studentov at 3,550 m, 8.0 km south; and Kulagash at 3,558 m, 21.2 km east.
This means the summit looks onto a dense ring of high ridges and peaks, with the highest mass of the range not far away. The outlook is dominated by the main crest of the Katun Range rather than by low foothills or broad plains.
The range
Yarlu belongs to the Katun Range, which spans Kazakhstan and Russia. Its highest peak is Belukha at 4,509 m, about 10 km south of Yarlu. The range has 34 named peaks in the reference set used here, and Yarlu ranks 19th by elevation among them.
That position places it in the upper middle of the range’s named summits: high enough to be part of the serious alpine core, but well below the range high point. The nearby passes and peaks show how closely packed the relief is across this section of the Altai.
Climbing routes
The easiest listed route is the north ridge, graded Russian 1B. It was first climbed in 1982.
With only one route, Yarlu is a mountain for climbers comfortable with a technical alpine ascent rather than a simple hike. A Russian 1B route usually asks for steady movement on steep ground, route-finding, and basic mountaineering skills, with conditions on the ridge likely to matter more than distance alone.
Climate and weather
These are estimates from NASA POWER climate data adjusted to summit height. At the summit, the warmest month is July at about 4 °C, and the coldest is January at about -25 °C. Around the mountain, precipitation is about 450 mm a year, with the wettest month in July at about 80 mm and the driest in January at about 10 mm.
The main weather hazards are typical of high Altai terrain: rapid changes, cold wind, snow even in the warmer season, and slippery rock or snow on exposed ridges. Summer can still bring unstable conditions, while winter and shoulder seasons are severe at this elevation.
Best time to visit
At summit height, the months with a mean temperature above freezing are June, July, and August. That makes the short summer the most practical period for climbing, especially when snow cover is reduced and daylight is long. Even then, conditions can change quickly on the ridge.
July is the warmest month and also the wettest, so it can offer milder temperatures but not necessarily the driest weather. For a climb on this height and terrain, visitors usually look for the stable part of the summer season and still prepare for cold, wind, and fresh snow.
Nature and wildlife
The mountain sits in a high alpine zone with rocky slopes, scree, snow patches, and sparse vegetation near the upper reaches. Lower down in the Altai, the landscape typically shifts to mountain forest and then to open alpine meadows before giving way to bare ridges and summit terrain.
The protected setting of Golden Mountains of Altai and Prirodnyy park <<Belukha>> suggests a mountain environment where wildlife can include species adapted to cold, steep country, and where human impact is limited compared with more developed regions. On the upper mountain, the main natural features are rock, snow, and exposed ridge terrain.
Guides and organised ascents
For a peak like Yarlu, a certified mountain guide is sensible if you do not already have experience on Russian-grade alpine routes, route-finding, and exposed ridges. 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 operators such as Alpindustria Tour in Moscow for mountain travel in Russia. Guided ascents usually depend on the number of days, group size, hut nights, and equipment needs. For this mountain and region, it is wise to ask about local logistics, weather windows, and whether any protected-area rules affect access.
Safety and preparation
Yarlu is a high alpine peak, so preparation should match steep ground, cold weather, and possible snow or ice on the ridge even in summer. Good boots, layered clothing, navigation skills, and the ability to turn back in poor conditions are important. The protected mountain setting also means you should plan carefully and travel with enough food, water, and emergency gear for changing weather.
For mountain rescue in Russia, the emergency number is 112, the unified emergency number. Rescue is run by MChS (EMERCOM). Groups are advised to register their route with the local rescue unit before setting out.
Interesting facts
Yarlu is 19th highest among the 34 named peaks in the Katun Range. Its nearest higher neighbour is Hora Járy Cimrmana, 2.3 km to the southeast. The highest peak of the range, Belukha, lies about 10 km to the south, so Yarlu sits fairly close to the main high point of the range.
The mountain is also part of a border-spanning range, since the Katun Range extends across Kazakhstan and Russia. Around the summit, the protected areas of the Golden Mountains of Altai and Prirodnyy park <<Belukha>> frame the mountain’s setting.
FAQ
How high is Yarlu? Yarlu rises to 3,370 m.
Where is Yarlu? It is in Russia, in the Altai Republic, within Katandinskoye rural settlement and Ust-Koksinsky Rayon.
What range is Yarlu in? It is part of the Katun Range in the Altai Mountains, within the wider South Siberian Mountains.
What is the easiest route up Yarlu? The easiest listed route is the north ridge, graded Russian 1B. The harder challenge is that it is still a technical alpine line, so climbers need experience on exposed terrain.
Is there water on the way to Yarlu? On the upper mountain you should expect snowmelt and dry ridges rather than reliable running water. Carry enough for the day, usually about 1.5-3 litres depending on heat and route length, and treat any meltwater before drinking.
Are there huts on Yarlu? 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.
How should I prepare for mobile phone coverage? 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.
