, with a length of about 20 km, depth ranging from 450 m to 1600 m and width from 400 m to some meters at its narrowest part.

Vikos is listed as the deepest gorge in the world by the Guinness Book of Records among others. This follows a somewhat arbitrary definition of a gorge that excludes deeper features such as Colca Canyon

Location

The gorge is the found in the core zone of Vikos–Aoös National Park, in Zagori
Zagori
Zagori , is a region and a municipality in the Pindus mountains in Epirus, in northwestern Greece. The seat of the municipality is the village Asprangeloi. It has an area of some 1,000 square kilometres and contains 45 villages known as Zagoria , and is in the shape of an upturned equilateral...

 region. It begins between the villages Monodendri and Koukouli and ends near the village of Vikos (or Vitsiko). The gorge collects the waters of a number of small rivers and leads them into the Voidomatis River which rises in the gorge. Voidomatis has a seasonal flow to its major part, being permanent only at the lowest part of the gorge. Vikos is also a site of major scientific interest, because it is in almost virgin condition, is a haven for endangered species and contains many and varied ecosystems.

Geomorphology

The Vikos Gorge, with a length of 20 km (12 mi), walls that range from 400 to 1600 ft (121.9 to 487.7 m) deep, and a width from 400 m (1,312 ft) to some meters at its narrowest part is listed by the Guinness Book of Records as the deepest canyon
Canyon
A canyon or gorge is a deep ravine between cliffs often carved from the landscape by a river. Rivers have a natural tendency to reach a baseline elevation, which is the same elevation as the body of water it will eventually drain into. This forms a canyon. Most canyons were formed by a process of...

 in the world in proportion to its width, though some gorge lobbyists contest that claim. The main part of the gorge stretches from the village of Vikos to Monodendri, and attains a depth of about 1000 m (3,281 ft).

The landscape of the 20 km long gorge, 12 km οf which belong to the park's core zone, presents a diverse relief and is characterized by abrupt altitudinal changes. Steep slopes and precipitous rocky cliffs dominate in the middle and higher zones respectively. Numerous gullies

s. The gorge, with a northwest-southeast direction, has been carved over millions of years by the Voidomatis River, a tributary of the Aoos. The Voidomatis, is mostly seasonal, with year-round flow occurring only in the lower part of the gorge. As the Vikos Gorge is a deep cross section, its slopes expose a series of rocks of different age. The upper layers consist of limestone

. A special feature of the limestone, resulting from its chemical weathering to water, is its carstic nature. Since limestone dissolves as the water percolates through its pores, an extended underground drainage system is developed with caves and channels that enlarge with the time when their roofs collapse producing rocky exposures and perpendicular slopes. For the same reason the water is scarce, and only when an impenetrable stratum
