The Eastern Anatolia region is the easternmost part of Turkey and it was formerly part of Western Armenia. It is the region with the lowest population density of Turkey and the main economic activity is agriculture and animal husbandry. Main cities are Agri (Ağrı), Van, and Erzurum. Van is located near the Turkish border with Iran on the shores of Lake Van, the largest lake in Turkey and one of the world's largest lakes without outlet. Erzurum is a university town and a popular winter sports destination in Turkey.
Eastern Anatolia is not popular among tourists, it is very remote, hard to reach, has little infrastructure and not much to see except semi-arid hills. There are some caves but not a single underground tourist site.
