Greek is the native language of most the people of Thrace. Most of the Muslims in Thrace are ethnic Turks and speak Turkish as a native language. In villages north of Xanthi, Pomaks, who are ethnic Bulgarian Muslims, speak Pomakika (a dialect of Bulgarian). However, most people also speak passable English and some may speak German or other European languages.
The new super-highway Egnatia can get you anywhere in the region within an hour or an hour and a half for the most remote areas. It connects all the major cities in Thrace from Xanthi to the border crossing with Bulgaria in Kastanies north of Evros or the customs with Turkey to the east.
Even the smallest rural villages can be accessed by using a combination of local run buses.
Frequent stops all along the region's sole train line and cities dotted along the Evros River. A scenic route for some but rather slow for the busy traveler.
SAOS will sail you to Samothraki daily or even more frequently during the summer period.
