Peristerionas is a very narrow and relatively deep gorge, crossed by the waters of Krathis river. The width at the bottom of the gorge is 5-6 meters, reduced to 2 meters at its narrowest point. On both sides has breathtaking towering cliffs, 40-50m high.
Krathis river has its springs on mount Helmos. Among them, is the so-called "Waters of Stygos" or "Immortal Water", where according to tradition, Achilles was baptized to become invulnerable. Another spring is Kryoneri, in the forest of neighboring Zarouchla. The waters of those two springs are joined near the village of Peristera, forming a single river with numerous meanders that crosses the mountains and forms small waterfalls and the impressive Peristerionas gorge. The river along with the waterfalls compose a magical setting.
Peristerionas gorge is located in the area of Akrata, in Peloponnese. It is a hidden gem of infinite natural beauty, just 2 hours from Athens, that only a few know. River trekking is relatively easy for both adults and children over 12 years old. The best spot to start hiking is the Voutsimos bridge, near Akrata. You first have to go downhill through a path in order to reach the river. Then, follow the current of the water and shortly after, you will come across the impressive entrance of the gorge. The view is captivating. In the middle of the gorge, water falls from the top of the cliffs, just like in the Panta Verhi gorge in Evritania.
