Vižaj (pron. Veezhay) is a river in the extreme north of Sverdlovsk Oblast, flowing east, a right tributary of Lozva, in a mostly uninhabited land of taiga, subarctic coniferous forest. It was also a nearby village, from which the Djatlov ski party set off on their fatal trip. As of 2021, it is the main home area where SGS conducts cave exploration.
