Parnonas is the large mountain complex that has its roots in Arcadia (just south of Tripoli) and extends with its branches to the southeasternmost cape of the Peloponnese, Cape Malea. It is a relatively unknown area with great variety and contrasts in relief and vegetation: alpine peaks, beautiful mountain forests, narrow gorges with impressive waterfalls, steep coasts and large sandy beaches, but also the most important wetland in western Peloponnese. The major project of detailed mapping of the area started a year ago and will be completed by 2009. The first map that has just been published covers the northern part (mainly Parnonas) from Dolianá and Ástros in the north to Chrysafa, Kosmas, and Poulithra in the south, two map sheets printed front and back. Brief information about the main mountain trails is provided in the margin of the map, such as the section of the E4 that crosses the mountain, the recently maintained and marked network of trails around Tsintzina, the ascents to the peak of Megali Tourla, and several other trails that connect villages throughout the complex.
