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. The narrow part of it is quite small and is approximately 1km long. It starts near the village Karoti and despite its small length it is surely worth a visit. It is accessible by everyone and its ideal for swimming in the ponds formed along it, however fences have been installed to keep goats inside.
