The Pindus (also Pindos or Pindhos) mountain range is located in northern Greece and southern Albania. It is roughly 160 km long, with a maximum elevation of 2,637 m (Mount Smolikas). Because it runs along the border of Thessaly and Epirus, the Pindus range is often called the "spine of Greece". The mountain range stretches from near the Greek-Albanian borders in Northern Epirus, entering the Epirus region and Macedonia region in northern Greece down to the north of the Peloponnese. Geologically it constitutes an extension of the Dinaric Alps, which dominate the western region of the Balkan Peninsula. This vast complex of mountains, peaks, plateaus, valleys and gorges traverses the Greek mainland from the Northwest to the Southeast. Its length reaches almost 230 kilometers and its largest width is 70 kilometers.
