In a beautiful and lush environment, at the foot of Koziakas at altitude 280 m (about 1000 inhabitants) located the village Diava. It belongs to the municipality Kalambaka and is 3 km from it. East of the village flows the Peneus River, natural border with the town of Kalambaka. In Diava belongs also the resort of Koromilia (altitude 1150m). The old name of the village was Preventa (= passage in the Vlach dialects from the Latin verb praevenio = passing. Interest are the post-Byzantine church of Agia Paraskevi, Agios Dimitrios and Agios Athanasios.
The river Penaeus separates Meteora from Diava. On the one hand the grandeur and the sublime beauty of the rocks with the global radiation and the other a landscape lush with Diava literally hanging from his arms Koziakas.
