The Gorge of Kandanos is a place of exquisite naturalistic and historical importance, which is today endangered by the operation of a large quarry. The Gorge of Kandanos hosted the first battle between armed residents against governmental troops in the history of the Second World War. On 24 May 1941, the residents of Kandanos fought against the Germans who headed towards Kandanos, the day after the battle in Floria, where all Germans, except one, were killed. On the occasion of this reason, the Germans razed Kandanos and the surrounding villages while executing dozens of civilians. Even today there has been no justice for the atrocities of the Germans at Kandanos and Floria, like all other martyr villages of Crete.
Apart from its historical significance, the canyon is full of cypress trees and dense vegetation. Moreover, the canyon is still crossed by the wonderful stone road that headed to Chania, built by the local people (at the end of the 1920s). The road is an excellent sample of preindustrial construction.
The upper part of the Gorge is named Spina Gorge, after the homonym village close to its start. The lower part, which starts from the point where the gorge meets the stone-built road (near Agios Irineos church) till Anavos is called Kandanos Gorge. However, they are actually the same ravine.
