Τhe biggest part of eastern Mount Mainalon, where the the highest peaks of the mountain are located, as well as the western part, with its lower and smoother terrain, is covered with fir forests. The monotonous landscape of indistinguishable limestone slopes with its dense or sparse fir forest is interrupted by several large hollow glades, called swallow holes whose size and dispersion is characteristic of mount Mainalon. The Menalon Trail runs across one of the largest swallow holes of the mountain, the Vlachika plateau, of an area of about 200 acres. Unlike the fir covered upland, the areas in the mountain periphery, through which the Menalon Trail meanders, has a greater variety of landscapes as a result of the synergy of two connected narratives of the landscape, the turbulent tectonic powers and equally troubled human path. On the wild but rich natural scenery of the gorges and the successive folds, man discovered the beauty of large head springs, riparian resources and sunny crests. There, somewhere between forest and rural areas, in locations naturally fortified or prominent, human settlements rallied and flourished. Around them, articulated in concentric isochronous zones, where human activities spread and each one of them depositing its own mark on the land, resulting in the diversity that characterizes the landscape throughout the Eastern Mediterranean. If the mountain talks in whispers, the landscape around the mountain is a resonant babble. In this zone, in Lousios Gorge, in the ravines of Mylaon and in the rocky terrain of Lagadia you will find the largest variety of flora and fauna in all Arcadia and among them many rare or unusual species.
