Kirov Oblast (Russian: Ки́ровская о́бласть KEE-ruhf-skuh-yuh OH-bluhst) is a region in the Upper Volga, bordering Nizhny Novgorod Oblast to the southwest, Kostroma Oblast to the west, Vologda Oblast to the northwest, Arkhangelsk Oblast and Komi Republic to the north, Perm Krai to the northeast, Udmurtia to the southeast, and Mari El to the south.
Kirov Oblast is probably about as close as you can get to a Russian version of the American "flyover state." The few sites of much interest to a tourist are in the capital, Kirov, but most Trans-Siberian Railway passengers will probably skip even that. If you ever get to the city, note that Kirov is home to traditional Dymkovo toys.
See Russian phrasebook.
Trains depart daily for Kirov from Moscow and take about 18 hours.
The Trans-Siberian Railway stops at Kotelnich, Kirov, and Zuevka (from west to east).
