Guloykhi, or Guloy-khi (inh|ГӀулой-Хий|Ghuloy-Khiy) is a river in the Dzheyrakhsky District of the Republic of Ingushetia, a right tributary of the Assa River.
The Guloykhi river originates in the eastern part of mountainous Ingushetia. It flows west along a mountain valley near several medieval tower settlements, most notably Gul, Läzhg, Qoyrakh, Abali, Vovnushki, Koki, and flows into the Assa near Puy and Tkhaba-Yerdy.[1] A forest mainly covers the left bank of the river.[2] The speed of the flow is 2.2 m/s. The mouth of the river is located 103 km along the right bank of the Assa at an altitude of 1112 meters above sea level.
