Thrace occupies the northeastern section of the Greek state. Its eastern and western limits are marked by two noble rivers, the Nestos and the Evros; to the north, the Rhodopi mountain range separates it from Bulgaria, while to the east, it borders on Turkey. Thrace can be reached by air, sea, and land.
The climate ranges from continental to Mediterranean with lots of rain and snow. Vast plains, such as those of Xanthi and Komotini, fertile valleys, such as the Evros Valley, great rivers, rich vegetation and large forests are characteristic of the region. The lakes and wetlands of Thrace are among the most important in Europe with perhaps more than three hundred protected species of birds.
