In the rugged terrain of Crete, rivers meet large faults and steep descents during their course through the canyons, forming hundreds of small and high waterfalls.
Crossing the gorges of Crete with high rappels is possible only by using technical equipment. Appropriate training in canyoneering techniques can be offered by specialist companies and clubs on the island.
Some of 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.

Kakoperatos Gorge 
Canyon Kakoperatos located 10km south of Ahendrias village, on the eastern side of Asterousia Mountains. The distance from Heraklion is approximately 66km. The gorge is only crossed with technical equipment.
The gorge of Goula is located south of the village Kapetaniana and ends at Agios Ioannis seaside settlement. Like the two other gorges of the area (Koumos and Gerakia) it is impassable without canyoning equipment
The gorge of Valahas is formed south of Heraklion and the beach Elygia is formed at its exit. The highest rapel is 50m high and 4 hours are required for its crossing (only with canyoning equipment). The lower part of the gorge is covered by pine trees.
The wild and inaccessible canyon of Mesosfini is located 55km south of Heraklion city, in an isolated area west of the seaside village of Treis Ekklisies. Its entrance is located at a height of 450m, near the village of Mournies and Prinias, in the Asterousia Mountains. At its exit, 2km south, it is formed the majestic beach of Voidomatis, which can be accessed via a dirt track from Tris Ekklisies.
One of the most impressive and longest canyons of the entire island of Crete is the canyon with the cacophonous name Psoraris (Greek: someone who suffers from scabies). Its exit is located at the mountains of Dikti, above the village Geraki and it starts from the plateau Parasyrta. There are three different mountain roads, all of unique beauty: from Lassithi plateau (village Kaminaki), from Geraki and Katofygi by Viannos.
On the southeast side of Afendis Christos summit, above the villages Embaros you will meet the verdant vineyards at Erganos plateau at 900 meters altitude. The water gathered from the melting snow of the surrounding slopes and from many springs of the region form the main tributary of the Anapodaris river, Baritis, which crosses the plateau of Erganos and forms the rugged canyon of Erganos.
The gorge of Psaro Nero is located 55km southeast of Heraklion. It is a short inaccessible canyon with high waterfalls (rapels), very well known to canyoners of Crete. Psaro Nero with its wonderful rock formations has water till late spring. It is initially open and closes abruptly close to the end, where the high rappels are (the highest is 25m). The gorge empties into Baritis River, a tributary of Anapodaris, near Katofygi.
The gorge of Eligas is a monument of natural beauty located on the west side of the mountain Koupa near the village Miliaradon by Embaros. It is actually a high waterfall with nine rapels, ideal for canyoning. The difference of altitude between the entrance and the exit is about 230m.
