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.
Xerokambos Gorge (Lamnoni) 
The gorge of Xerokambos – Ziros, officially called “Lamnoni gorge”, is the driest canyon of eastern Crete. Walking in the gorge takes approximately 2 hours and the descent is quite easy and smooth. The canyon has typical wild cretan beauty, with bare, tall walls and undergrowth. Throughout the journey, you'll admire the view to the blue Libyan Sea.
Chosti Gorge 
The canyon of Chosti is formed by the small settlement of Hosti in Chania, amid one of the most beautiful and lush green places of Crete. Away from the known tourist routes, it remains completely unknown and yet untouched. You will not find in any tourist guide referring to it, though it is a jewel of western Crete and is one of the most beautiful small canyons small, which can be easily crossed without any canyoning equipment.
Panagia Keralimeniotissa Gorge (Kalami I) 
The canyon of Panagia (Virgin Mary), also known as Kalami I is parallel to the gorge Xerofarago or Kalami II and takes its name after the former monastery of Panagia Keralimeniotissa located at its exit.
The exit of the gorge Tsigounis is located 1km west of the village Sfaka, Sitia district, on a turn of the main road connecting central Crete to Sitia. The river flowing through the gorge gets its water from the plateau Monokara and is "stingy" (tsigounis means stingy) as it has small quantities of water only in winter.
Kissos Gorge 
Kissano Gorge is located 1km north of Kissos village, in Amari valley, and 34km southeast of Rethymnon, connecting the village το the small plateau of Gious Kambos. It is a short, but beautiful gorge, crossed by the rural road of the area.
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.
The canyon of Koudoumis is located about 27km west of Sitia, near the village Tourloti. The canyon is accessible on foot, but it has six small steep rappels that require little attention. The canyon is also called Tourloti Gorge as its exit is located close to Tourloti and its entrance is located at the small plateau of Monokaras, a few kilometers further south. The impressive rock formations and the blooming nature of spring make trekking in Koudoumis gorge very interesting.
West of the village Rogdia a small gorge is formed that exits at the area of Paliokastro. It initially starts at position Koukos, where we meet the ruins of an old watermill.
