The city is situated on high hills and surrounded by volcanoes. In fact, the horizon cannot be seen clearly from any point in town as volcanoes and mountains are everywhere. Across Avacha Bay from the city is Russia's largest submarine base, the Rybachiy Nuclear Submarine Base, established during Soviet times and still used by the Russian Navy. The city is located 6,766 kilometers (4,204 mi) from Moscow (about nine hours by plane) and about 2,220 kilometers (1,380 mi) from Vladivostok
