The Odontotos rack railway was constructed so as to connect Kalavrita to Diakopto and it is 22 km in length. The railway track is 75 cm in width which is unique in Europe. The whole journey lasts about 60 minutes and the speed of the train ranges from 30 to 40 km per hour. In some places throughout the journey there are toothed rack rails due to the large inclination of the tracks. The train stops at the stations Niamata, Triklia, Zahlorou and Kerpini. It is worth mentioning that the journey next to Vouraikos river is just enchanting.
The Cave of the Lakes
Two kilometres north of the village of Kastria and 17 km south of Kalavrita at an altitude of 800 metres there is the Cave of the Lakes. This cave is characterized by a quite spacious entrance that is 3.5 metres tall and 6.5 metres in width. The cave is 2 km in length and it has 13 lakes that are separated by stone walls. Approximately 500 metres of the cave have been used and one can enter through an artificial tunnel. Various small bridges have been built to facilitate the visitors crossing the cave. The Cave of the Lakes has been incorporated in the network Natura 2000.
At an altitude of 800 metres there is one of the very few lakes that exist in the mountainous Peloponnese. It is the Tsivlou Lake. A landfall that took place in 1912 was the reason it was created, as the ancient river Krathis was blocked. Around the lake there is a road ideal for walking and for other kind of activities, such as mountain biking or having a picnic.
The Vouraikos Gorge starts between Helmos and Panachaikos mountains, about 3 km away from them, and it reaches Diakopto. Vouraikos river springs from the mountains in Kalavrita and it stops at the Corinthian Gulf next to the beach of Diakopto. As the years went by, a deep and incredibly beautiful gorge was formed. Then on, due to a large amount of water flowing from streams many small lakes and beautiful waterfalls were built. The gorge is characterized by rich flora and fauna and it is part of the network Natura 2000.
