Covering an area in which you can fit in fourSwitzerlands with still some more room, but with a population of just over 6 million, Eastern Anatolia is all about vast landscapes of mountainous terrain, with occasional flat-ish plateau inflitrated inbetween.
In the eastern and southeastern areas (near Iranian border and around Lake Van) of the region, the mother tongue of most locals is Kurdish. However most locals, especially younger ones, are also bilingual in Turkish, although heavily accented in most cases.
Erzurum is the main gateway to the region with fairly frequent air, bus, and rail connections with the rest of the country. Other secondary-major cities with airports include Malatya, and Van, both of which also has rail links with the rest of the country, and with Iran in the case of Van. Occasionally potholed (but getting better and wider day by day) highways connect the region to other Turkish regions in north, south, and west; and to Iran to east.
Muradiye Waterfalls (Muradiye Şelalesi). A quite large waterfall, usually getting frozen in winter. It is north of Muradiye, which is about 80 km north of Van, off the highway to Doğubeyazıt.
