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.
Trabzon is the main hub of transportation into the region.
Trabzon is the site of the sole airport in the region, with links to the big cities in the rest of the country.
Trabzon, and Rize to a lesser degree, are served by frequent buses from rest of the country, especially big cities such as Istanbul and Ankara. However, as the region lies on the far northeastern corner of the country, distances are huge and bus ride from, for example, Istanbul can easily take a full day and night.
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.
Central Karadeniz to west is the extension of the Black Sea coast, yet with less mountains and much more plains.
Eastern Anatolia to the south, just over the Pontic Mountains, is high territory with cold weather—even in summer—and is almost a world apart from the coast.
