Rethymnon hosts several accessible beautiful canyons. The most famous is the Gorge Kourtaliotiko, in which flows the river Megalos that ends at the beautiful beach of Preveli with the dreamy palm grove. The gorge has the largest quantity of water in Crete and river trekking along its bed, from the springs to the beach, is an exciting experience. Other hiking-friendly canyons of Rethymnon include the twin Kollita gorges at the area of Argyroupolis, the gorge Kotsifos by Plakias, the gorge of Saint Anthony at Patsos, the gorge Prasano and the gorge Platania. Next to the town of Rethymnon there are the lush canyons of Myli, Vederi and Gallos.
The beautiful canyon Galliano starts southeast of Gallos and ends at the town of Rethymnon. It is 5.5km long and the walk is along a verdant ravine. Along the way we meet the mill of Saounatsides used till the 20th century, with traces of an old chapel next to it. In the gorge there is also the temple of St Anthony.
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 at 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 Arkadi starts just north of the Arkadi monastery and after a scenic route of 2 hours (some parts along the bed of the gorge as it is inaccessible), it ends near the village Pikris, where visitors can admire important Venetian architectural monuments. In the gorge of the exceptional natural beauty, the visitor has the opportunity to admire representative species of Cretan flora and fossils.
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.
Approximately two kilometers northwest of the village Karines at position Faragi there is a small but impressive gorge, Kariniotiko Gorge. Kariniotiko canyon is completely unknown as the entire surrounding area is not included in the tourist routes. However, the surrounding area has exceptional natural beauty and hosts one of the most impressive oak wood of Crete with huge ancient trees.
Kollita Gorges, i.e. Twin Ravines are located nearby the picturesque village Argyroupolis, about 22km southwest of Rethymnon city. They are named so, as they consist of two parallel canyons that end near Kato Poros settlement. Here we refer to the easternmost gorge of Moundros.
The lush canyon of Vederi starts from the village Fratzeskiana Metohia, passes next to the village Vederi and ends on the beach of Gerani (after 7km). The canyon has dense vegetation that makes trekking very difficult, as there is no footpath along its length.
The canyon is formed north of Rodakino village and is inaccessible without the use of canyoning equipment. It starts south of the summit of Kryoneritis Mount and after 5km it merges with the canyon of Sykia, just before reaching the bridge of Rodakino.
