The Parnon is the large mountain complex that has its roots in Arcadia (a little south of Tripoli) and extends with its branches to the southeasternmost cape of the Peloponnese, Cape Malias.

It is a relatively unknown area with great variety and contrasts in its terrain and vegetation: alpine peaks, beautiful mountain forests, narrow gorges with impressive waterfalls, steep cliffs, and large sandy beaches, as well as the most important wetland in western Peloponnese.

The major undertaking of detailed mapping of the area began a year ago and will be completed within 2009. The first map that has just been published covers the northern section (the main Parnon) from Dolianna and Astros in the north to Chrysofa, Kosmas, and Poulithra in the south, with two map sheets printed back-to-back.

The margin of the map provides concise information on the main paths of the mountain, such as the section of the E4 trail that crosses the mountain, the recently maintained and marked network of paths around Tsingina, the ascents to the peak Megali Tourla, and several other paths that connect villages throughout the complex.
