Vikos gorge is one of the most popular hiking destinations in Greece. The gorge consists of limestone and dolomite formations dating back to 150 million years ago and vertical walls extending up to a height of 1700 m. The hike starts from Monodendri village with a 45-minute descent towards the river bed. The trail is ascending and descending surrounded by steep mountain tops and dense forests of deciduous trees and 1800 plant species. Before ascending to Vikos village, visit the Voidomati Springs, Greece's cleanest and coldest river, with an average all year temperature of 8.5°C. If you are brave you might want to try the experience of a very refreshing dive in the crystal clear waters during summer months. The hike finishes at Vikos village, after a 1-hour ascent from the Voidomatis springs.
