This is one of the largest massifs in the Pindos range. It lies north of the Timfi range separated from it by the deep valley of the Aoos river. Another deep valley separates Smolikas from Mt Gramos on the Albanian border. Smolikas is of particular interest because its largely composed of serpentinite, a rock type rarely found in Greece, and which has a distinctive flora. Pinus nigra dominates the forests from about 1000m, replaced by Pinus heldreichii from 1500 until 1800m.
