Enipeas is a river of Pieria, which runs through Litochoro. Its canyon has evolved and exploited to an extent that attracts many tourists every year. The name of the river comes from a sea goddess, father of Pelias and Nileas and wife of Tyros. It is a personification of Neptune. The same divinity is also found in Thessaly and Ilida. Again according to Mythology, the Orpheus musician was devastated by the Maenads, and the beautiful Leto was bathed in the river.
