Oligyrtos mountain, also known as Skipiza (it’s highest peak), lies on the border between Arcadia, Argolida and Corinthia regions; it also has a strategic position between the lakes Stymfalia, Feneos and Kandila. Its peaks reach high altitudes; the highest, as mentioned, is Skipiza at 1,935 metres, then is Gkirmpini at 1,831 metres, Skiathis at 1,777 metres and Mavrovouni at 1,694 metres. On the mountain’s east Mainalo mountain is visible, Trachy on the south and the mythical lake Styphalia can be found in the northwest.
Climbing the mountain to the top, one founds forbidding rocky slopes and thorny bushes, as well as brushwood covered forests of sclerophyllous trees. Dense forests of Greek Fir (species Abies Cephalonica) cover the mountain’s northern part, of about 21,500 acres; its southern suffers from overgrazing, and as a result, is only sparsely populated by oaks and remains of older forests or maquis. Alpine meadows can be found on the mountain, since in parts it is less forbidding; this milder geographical terrain can be seen on the peak, as well, allowing for easier access. A perfect starting point for such a hike are the villages Kandila in Arcadia, and Lafka of Corinthia, built on the north-eastern slopes of the mountain. Another interesting feature of the mountain are its many springs; especially on the southern slopes and in and around Lafka village.
Oligyrtos mountain is part of the Natura 2000 treaty because of its significant biodiversity, and is part of Corine treaty because of its protected biotopes. Six protected species of mammals have been found, as well as four amphibians and fourteen reptiles. The area is also populated by several species of woodpecker, such as the rare Golden Eagle. As for the mountain’s rich flora, noteworthy is the native Viola Oligyrtea, as well as the Kyllini native species Adonis Cyllenea.
