Elatia (Greek: Ελατιά, Ελατιάς), until 1927 known as Kalyvia Koutra or Kara Dere (Greek: Καλύβια Κούτρα, Καρά Ντερέ, Καράντερέ, Bulgarian: Кара дере[1][2][3]), is a forest village in Northern Greece near the border with Bulgaria.

[1] After the Russo-Turkish War the village of Elatia (Kalyvia Koutra or Karadere) remained within the borders of the Ottoman Empire and its population consisted of Pomaks[4] and occasionally some Sarakatsani families who used to stay there in summers.

[2] The village was depopulated in the period 1919–1934,[3] most probably in 1923 as a result of the Treaty of Lausanne.

Since then the village remained a place for Sarakatsani in the summers, and nowadays it serves as a center of the forestry enterprise of Elatia mountain and as a tourist station and mountain refuge.
