About The Place

The Vouraikos Gorge is located in Achaea, 13 kilometers northeast of Kalavryta. Together with the mountain range of Mount Helmos (also known as Aroania Mountains), it constitutes a unified protected area that has been designated as a National Park of Greece since 2009. The gorge stretches for approximately 20 kilometers and is traversed by the Vouraikos River, from which it derives its name. The Vouraikos River is located in Achaea and has a length of 37.5 kilometers.

The flora of the Vouraikos Gorge is considered remarkably significant, as it is home to several endemic species with special scientific value, some of which are rare and protected, such as Campanula rupestris (rock bellflower), Stachys parolinii (wild spike), Aurinia moreana (Morina alyssoides), among others. The wildlife of the area also finds refuge in the steep forested mountainous slopes surrounding the gorge.

In 1889, within the gorge and alongside the Vouraikos River, construction began on the unique cog railway in Greece, initiated by the government of Charilaos Trikoupis. The study was entrusted to French scientists. Charilaos Trikoupis envisioned the railway line extending to Tripoli, but delays in the construction of the Diakofto-Kalavryta line and cost overruns ultimately prevented the railway from ever being extended. The construction of the cog railway was completed during the administration of Georgios Delyannis in 1896 and was inaugurated on March 10, 1896. It connects Diakofto to Kalavryta, with a total length of 22 kilometers.
