Eastern Karadeniz is a region in Black Sea Turkey, including the Artvin, Giresun, Gümüşhane, Rize, and Trabzon provinces.
A humid and verdant region as a consequence of the high precipitation levels distributed even throughout the year, the biodiversity of Eastern Karadeniz reaches the levels of tropical rainforests in some areas. Most of the higher parts of the mountains which dominate the region and usually ascending right from the coastline and giving way for little land for development are covered with lush forests, while yet highest parts are covered with alpine meadows and glacier lakes with the lower foothills are mostly tea plantations—a subtropical plant which can grow abundantly in the region thanks to the shielding effect of Caucasus Mountains from the cold northern winds in addition to the generous rainfall.
Eastern Karadeniz is the part of the region which Turks mostly think of when they hear Karadeniz, i.e. Black Sea.
The highway D010, which was recently upgraded to motorway standards, closely follows the coastline—sometimes too closely that it replaces the coastline as the motorway was built at cost of almost all of region's beaches, and forms the main backbone of transportation in the region from one end to another.
