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.
Anydri Gorge 
The small but impressive gorge of Anydri is located east of Paleochora. It starts from the village Anidri and after a snaky course, about 3km long, between high cliffs it concludes at the beautiful beach Gialiskari.
Roza Gorge 
The gorge of Roza is an offshoot of the gorge of Ambelos. It starts from a point near the rural road that crosses the gorge of Ambelos and has east-southeast direction, leading to Kera.
Portela Gorge is located at the south of the prefecture of Iraklion; the canyon starts from Hondros village and its exit is in Keratokambos. It is one of the most dangerous canyons in Greece.
The gorge of Ambas is located 53km south of Heraklion, in Asterousia Mountains. Starting from the small plateau formed near the village Paranymfi (710m altitude), it ends at the beach of Treis Ekklisies. This is a large (4km long) and beautiful canyon with many narrow passages, which is accessible only by experienced canyoners.
Martsalo gorge has a length of about 2km and is located in the south coast of Asterousia Mountains, in Heraklion Prefecture. It starts from the north and ends at the Libyan Sea, in the small picturesque beach of Martsalo. Apostle Paul stopped in Martsalo, during his journey to Rome.
Platania Gorge 
Platania Gorge is located in the Amari valley, 38km southeast of Rethymno, on the western outskirts of Psiloritis. It is a unique trail, with impressive cliffs, vertical limestone rocks, rock roofs and caves. The trail is recommended for experienced mountaineers, although the first part of the trek is quite easy and well pathed, even for children who are physically fit.
Petres Gorge is located 13km west of Rethymno and its mouth is situated on the beach of Episkopi. The river of the gorge is fed by the waters of Kollita Gorges and the surrounding area, covering almost half Rethymnon Prefecture. It has water all year round and forms an important wetland of Crete, especially at its mouth near Episkopi.
Through the gorge of Lissos passes the trail that connects Sougia to Ancient Lissos. It's a long canyon with imposing towering walls, but the path that leads to ancient Lissos covers only a small part of the route, taking only about 1 hour.
