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.
Koudoumas Gorge 
The gorge Koudoumas starts at an altitude of 1000m near the base of the highest peak of Asterousia Range, Kofinas, and ends on the beach of Koudoumas Monastery.
Rechta Gorge at Kolokasia 
At the lowest point of the ruined village Kolokasia, Sfaki Provice, at the church of the Virgin Mary starts forming a stream. The stream collects the water of the village. After crossing the olive grove of the village it turns to a small, but rugged, gorge called Rechtas or Rektas. Its name means waterfall in the local dialect. A few meters after the start the gorge it forms, indeed, a spectacular waterfall about 20 meters high.
Gorge Koumos is located at the area of Kapetaniana and it ends near the seaside settlement of Agios Ioannis, in a area full of pine trees. It is an unknown gorge and it can only be accessed with technical equipment. It is generally dry but after some heavy rainfalls it forms spectacular waterfalls.
Kaminolakos Gorge 
Below the village Myrthios of North Rethymnon (not the village Myrthios by Plakias) a small ravine with plane trees is formed, with a small and very wild gorge formed at its exit at position Kaminolakos. The gorge is dry and carries water only after heavy rainfall.
Half an hour above the archaeological site of Lissos, in a totally secret position called Lichnou Laki there is a small and very beautiful canyon. The gorge is located in the district of Selino, below Prodromi village, south of Chania and its entrance is accessed by a dirt road that runs from the village (to the south). The very small canyon is quite green and is divided into two different sections. The first section is dominated by lentisks, junipers and oaks and the second is covered by pine trees despite the destructive fire that had previously burnt the region.
Adjacent and parallel to the current highway linking Heraklion to Messara plane, between the villages Prinias and Avgeniki, a beautiful canyon is formed. Its descent requires the use of canyoning equipment, as it forms some steep descents.
On the southeast side of Mount Sanida, near the village Skourvoula, a small but very wild gorge is formed called Rizopetro. The gorge ends near Faneromeni dam after a very impressive 60m high waterfall, having water only after heavy rainfalls.
Petinos Gorge at Lithines 
The small gorge of Petinos or gorge Anavryta is shaped northwest of Lithines village, Sitia province. It is a technical gorge, meaning that crossing it requires canyoning equipment, as along it's course it forms about 12 waterfalls, with the highest reaching about 20m.
