The route starts from the village Peristera or Solos situated at an altitude of 1,000 m. Near Lake Tsivlou. Initially we follow a forest road that passes through pine forest and continue on the path that leads to the waterfall Waters of Styx.
The waters of Stygos are the sources of the Krathi River in Helmos of the Kalavrita District in Achaia at an altitude of 2,100 meters. According to mythology, Styga was an Oceanic woman who had her palace in Tartarus and keeps her day-long nights of uncaring dragons. It was believed that the waters of the spring were coming from there, from Tartarus and the palace of Styx.
In Titanomachia it was with Jupiter when he fought his father Saturn. Her children were the Kratos, Via, Zilos, and Nike. All the gods, even the Sun, swore in the waters of Styx: it was the greatest vow that a god could do, and the gods were punished there when punished. They said that whosoever was alive drank from her water was dying, and any metal that dipped it in her waters was melting. There he dug Achilles his mother Nerida Thetida and became intact, but he held him from the heel and remained the only vulnerable spot in his body.
