Kotsifos Gorge, Natural canyon in southern Crete, Greece.

Kotsifos Gorge is a gorge on the southern side of western Crete, west of the Kouroupa mountain and north of Plakias, cut by a stream that is usually dry in the warm season. The road from Kanevos, at about 450 m, descends through serpentines to a narrows where the overhanging rock walls almost touch; lower down the gorge widens and opens onto the Bay of Plakias, flanked by bare walls over 200 m high.

The road through the gorge was only asphalted in the 1960s; it links Rethymno with Chora Sfakion and Plakias. In the night of 13 March 2024 a large wedge of rock broke from the wall near the northern entrance, tore away steel safety nets installed weeks earlier and destroyed the road and its substructure.

The gorge's name comes from the Greek word for blackbird, kotsifos, and the road through it was only asphalted in the 1960s. The asphalt links Rethymno with Chora Sfakion and the resort of Plakias, so the gorge is crossed by traffic rather than walked by pilgrims.

The hiking trail starts at Kanevos village and leads to the Bridge of Sellia, taking roughly one hour for the main section. The ground is rocky and steep in places, so sturdy footwear and careful footing are important.

The gorge is home to many plant species found only on Crete and nowhere else in the world. Where it meets the neighboring Boutsinas gorge, a waterfall drops impressively between the rocks.
