We will find ourselves in Oiti, one of the largest mountains of Roumeli with an altitude of 2,152 m., full of rich vegetation, water and rivers. In the north and east sides there are slopes, deep gorges and wild bas relief, but at higher levels of the mountain, it becomes extremely smooth with green meadows, small ponds, springs, waterfalls and thousands of wildflowers. It is covered by extensive forests of Kefalonia fir, while chestnut trees, oak trees, cedars, cherry trees, wildflowers, holm oaks, maple trees and other 1250 species of fauna of high ecological value. Wild goats, deer, wild boar, foxes, hares, squirrels, badgers, ferrets etc. are found here. On the west side of the mountain is the Inachos River, while to the east side the rivers Gorgopotamos and Asopos end up in Sperchios grand river. To the south side, Oiti is known for the various streams that form Mornos river and the lake of Mornos. Oiti is also famous for its medicinal herbs, such as ellevoros, St. John's wort, etc.First, we will reach the district of Kato Pavliani and then, after 1-2 km, Ano Pavliani. Both neighborhoods have a permanent population of about 500 people. The place is full of firs, walnut trees, apple trees and chestnut trees. Among them the springs of Asopos create an excellent park, the Aesthetic Park of Pavliani. When we will arrive there, we will create two groups, the first will to walk through the Park and the second will follow a mountaineering route from Ano Pavliani to Heracles' Fire.Group A will hike on a magical journey through fir trees, plane trees and apple trees, a path where the colors of ancient trees and water reflect, and will end up in the heart of the natural park. The wild beauty that will fascinate you and make you feel like you are in a fairytale! Most of the remaining route is next to the river and above it, as we find many bridges. The hiking route is easy, with gentle slopes, ideal for everyone but especially for those who feel like children, since there are pleasant surprises at every step: Swings over the river, colorful fabric hanging hammocks, a volleyball court on paneled wood and wooden stands for the viewers, a trampoline literally in the middle of nowhere, wooden tables and tables for board games, funny labels with smart messages and many more. The playful mood in combination with the unbelievable beauty of the Park are the ingredients for the sure success of our hiking.Group B will follow a delightful journey through the fir forest with intense scents and spring pictures of wildflowers to the south side, going up to the sink and Hercules Fire. From the sink, where the waters of the plateau are lost in a great precipice of rocks and finally come out of the sources of Gorgopotamos, we will continue hiking to have a splendid view of the Giona peaks and end up in the Hercules Fire, once a place of worship of the mythical hero. A wonderful route that will create amazing impression to us.Final meeting point for all, Ano Pavliani, where we will enjoy a delicious meal at the local tavern.
