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.
Kandanos Gorge 
The Gorge of Kandanos is a place of exquisite naturalistic and historical importance, which is today endangered by the operation of a large quarry. The Gorge of Kandanos hosted the first battle between armed residents against governmental troops in the history of the Second World War.
Kakoperatos Gorge 
The canyon Kakoperatos is located by Agios Vasilios village at the province of Agios Vasilios. It’s a tributary of the Megalos River (Kourtaliotis) and as its name suggests (bad passage in Greek) it cannot be accessed from humans (by trekking).
Mesonas Gorge 
Mesonas gorge is located on the northern slopes of the mountains of Thripti, near villages Kavoussi and Avgos. It is a short imposing gorge (4km long), that needs technical equipment for crossing it along its bed. The canyon connects the Plateau of Thripti to the plain of Kavoussi.
The Gorge of Swallows is located 33km south of town of Rethymno city, next to the famous beach of Preveli with the majestic palm grove and the stunning river. It starts close to the village Drymiskos, runs almost parallel to the canyon of Kourtaliotiko (that of Preveli) and ends at the beach of Drymiskiano Ammoudi. It’s name is taken after the the swallows that arrive in the area every summer.
Embasa Gorge 
Gorge of Embasa starts its course from the village Kato Kera and ends near the village Gonies, being about 2km long. Its upper part is very steep and in winter several waterfalls are formed, with the highest being about 20m high.
Throughout its short length its hides two key surprises. First, it hosts a small colony of Cretan date palm trees (Theophrastus palm trees), while at the end of it, by the sea, some ponds with fresh water are formed. Especially these springs are an unexpected view in the hot and dry East Crete.
Platys (i.e. wide) river is one of the rivers of foremost importance in Crete, flowing all year round. It gathers almost all water quantities of Amari Valley and leads them to the beach of Agia Galini. At a secret location between the settlements Agia Paraskevi, Vyzari, and Petrohori, the wide river gets narrow and forms two impressive ravines. The first is the small Mesa Faragi (inner gorge), reminding of the gorge of Kourtaliotis.
The Gorge of Tromarissa is located near the village Zourva and it is said that it gets its name after the myths about fairies and goblins that scared passersby at the position where we meet the spring of Tromarissa (tromazo means get scared in Greek).
