How to drive the steep Pereval Mazar-Asjuu in the Tien Shan?

Pereval Mazar-Asjuu is a high mountain pass at an elevation of 3,832m (12,572ft) above sea level, located in the Chuy Region of Kyrgyzstan. Situated in the Kyrgyz Alatau range of the Tien Shan mountains, this rugged gravel track is a true test of high-altitude driving.

The pass is located in a high-alpine environment where the landscape is dominated by steep rocky cliffs and deep valleys. Due to its extreme altitude, the summit is subject to heavy snowfall for most of the year, making the road impassable outside of the short summer window. It is a wild and remote region where self-sufficiency and a capable 4WD vehicle are essential for any traveler venturing away from the main transit routes.

How challenging is the climb to Pereval Mazar-Asjuu?

The ascent to the summit is notoriously difficult. Starting from the asphalted Pamir Highway (M41) at 2,091m above sea level, the climb spans 18 km (11.1 miles). During this distance, you will tackle a massive elevation gain of 1,741 meters. The road features 25 sharp hairpin turns that wind steeply up the mountain flank. With an average gradient of 9.67% and sections hitting 15%, maintaining traction on the loose gravel surface requires low-range gearing and careful throttle control.

Where does the Mazar-Asjuu road start?

The road begins north of the famous Töö-Ashuu Tunnel, branching off into the high ridges of the Kyrgyz Alatau. Because the track is not regularly cleared of snow, it can be closed at any time depending on weather conditions. The descent and ascent are narrow and exposed, with significant drop-offs that are not for those with a fear of heights. This is a journey through the heart of Kyrgyzstan's high country, where the road conditions are as unpredictable as the stunning mountain vistas.
