For millions of years, the geological upheavals are reflected strongly in the intense relief of Crete. While mountains rose, the river water continued its corrosional route through the limestone terrain, forming today's "land of gorges", Crete. With more than 400 canyons, Crete hosts the largest number of gorges in Greece. Many travel agencies offer packages for gorge trekking and there is are several hiking and mountaineering clubs based in Heraklion, Chania, Rethymnon, Agios Nikolaos, Sitia, Ierapetra and Mires.
Cretan rivers meet large faults and steep descents during their course through the canyons, forming hundreds of small and high waterfalls. Crossing gorges of Crete with high waterfalls is possible only by using technical equipment. Appropriate training in canyoneering techniques can be offered by specialist companies on the island. The most popular technical canyons of Crete include the imposing gorge Ha, Tsoutsouras, Kalami, the gorge of Arvi (which after an 80m high fall turns into a dark underground river) and many more.
Havgas Gorge (Kalamafka) 
The Gorge of Havgas is located very close to the village Kalamafka, just 12km north of the city of Ierapetra. Note that there are several other gorges with the same name around Crete, such as the Havgas Gorge in Lassithi Plateau.
Asfendou Gorge 
The canyon of Asfendou is one of the many gorges in Sfakia province, starting from deserted hamlet of Asfendou that currently houses some local sheep herders. Along the canyon runs a passable but steep trail, parallel to the streambed. In many places the Libyan sea is visible.
Arkadi Gorge 
The Gorge of Arkadi starts just north of the Arkadi monastery and after a scenic route of 2 hours (some parts along the bed of the gorge as it is inaccessible), it ends near the village Pikris, where visitors can admire important Venetian architectural monuments. In the gorge of the exceptional natural beauty, the visitor has the opportunity to admire representative species of Cretan flora and fossils.
The Gorge Selinari is located about 45km east of Heraklion and 21km west of Agios Nikolaos, on the eastern slopes of Selena Mount. It is well known to all Cretans, because the National Road from Heraklion to Agios Nikolaos runs along the gorge.
Kavousi Gorge 
Kavousi Canyon is located near Keratokambos (near Ano Viannos, south Heraklion) in Dikti Mountain. The total length is 1km and the altitudinal difference between entrance and exit is 170m.

The beautiful canyon Galliano starts southeast of Gallos and ends at the town of Rethymnon. It is 5.5km long and the walk is along a verdant ravine. Along the way we meet the mill of Saounatsides used till the 20th century, with traces of an old chapel next to it. In the gorge there is also the temple of St Anthony.
The Knosano Gorge (or gorge of Saint Eirini) is the continuation of Mount Giouchta. It extends south of Archanes (Saint Mamas) it runs through Archanes in Kato Milos, where starts the subpart of Knossano gorge known as Sylamos Gorge, after the nearby village.
