Cheka, Mountain summit in Southern Urals, Russia.

Cheka is a mountain summit in the Southern Urals where visitors reach an elevated vantage point overlooking forested valleys and distant ridges. The peak reveals the undulating terrain of the region with its mix of rocky outcrops and vegetated slopes.

Cheka was designated a nature monument of Chelyabinsk Oblast by decision No. 361 of the regional executive committee on 6 October 1987. The protected area covers 397.15 hectares, with boundaries 9.4 km long following field roads. Its slopes and summit expose granitoids, and the site preserves the highest point of southern Chelyabinsk Oblast.

The mountain's name likely derives from the Kazakh word shoky, meaning a hill with a pointed top; the 19th-century geologist G. P. Helmersen recorded it as Kara-Chek, or Black Hill. Followers of new religious movements call Cheka "Gora Vlasti" or "Kailas" and hold mystic rites on the summit, which can damage the local nature when crowds gather.

Visitors should approach the ascent with sturdy footwear and weather-resistant clothing since conditions at the top change considerably. The route includes steep sections and requires moderate hiking experience.

On the summit is a Neolithic sanctuary, part of the Cheka archaeological complex, which also includes more than ten burial and memorial complexes of early and late nomadic eras on the peaks and ledges, and a Bronze Age alley of menhirs 4.5 km northeast of the main summit.
