Chasia (Greek: Χάσια) is a forested mountain range in the northern Trikala (Thessaly) and the southern Grevena (Western Macedonia) regional units, northern Greece. It is an eastern extension of the Pindus mountain range. The elevation of its highest peak, Kratsovo, is 1,564 m (5,131 ft). It stretches from the village Korydallos in the west to Kerasoula in the east, over a length of about 35 km (22 mi). The nearest mountains are the Antichasia to the south, the Kamvounia to the northeast and the Lygkos (northern Pindus) to the west. It is drained by tributaries of the Aliakmonas to the north, and by the Pineios and its tributary Mourgkani to the south.
The Pineios (Greek: Πηνειός, romanized: Pineiós, Modern Greek:[pi.ni.ˈos], Ancient Greek:[pɛːnei̯ós], referred to in Latin sources as Peneus) is a river in Thessaly, Greece. The river is named after the god Peneus. During the later Middle Ages, it was also known as the Salamvrias or Salavrias (Σαλα[μ]βριάς).
It flows from the Pindus mountains through the Thessalian plain and empties into the Aegean Sea, northeast of the Vale of Tempe, near Stomio. It creates a large delta, well known for its beauty and for many animal species, protected by international environmental treaties. Its total length is 205 km. Its drainage basin is 9,500 km (3,700 sq mi). Its source is near the village Malakasi, on the eastern slope of the Pindus main range, east of Metsovo. The Meteora region and the city of Larissa lie along the Pineios. Trikala lies on its tributary, the Lithaios. In the 1960s, a freeway connecting Athens and Thessaloniki was constructed in much of the Vale of Tempe.
