Enipeas is a river of Pieria, floating through the town of Litochoro. Its canyon attracts many tourists every year. The name of the river comes from some sea deity, father of Pelia and Nilea and husband of Tyro. This is the personification of Neptune. The same deity is found in Thessaly and in Elis . According to Mythology, the musician Orpheus was destroyed by the Maenades in the Enipeas Gorge, while the beautiful Lito was bathing in the river .
Enipeas has its springs at the site of Prionia, at an altitude of 1000 meters. The foothills along it are natural pools. The water temperature is just above zero degrees Celsius and swimming should be done with care. Paradoxically, the route along the river (either uphill or downhill) is not one of Olympus's most popular. Most climbers prefer to bypass it and climb up to Prionia by their car and from there continue to climb up the high peaks. This route, however, is one of the most beautiful and darkest. It is suitable for all ages and is ideal for family outings and overnight stays with relative safety. The trail starts from Litochoro (Mili location) ) at an altitude of 300 meters. It is 9 km long and a moderate traveler will arrive in Prionia in 5-6 hours. The water of the river is drinkable in almost all its parts and it drains Litochoro.
The route from Prionia (1100m) to the "Spilios Agapitos" refuge (2100m) is the most frequented Mount Olympus trail, part of the E4, and is the natural continuation of the Litochoro - Prionia route. Prionia is the last point we can drive by car (it is 18 kilometers from Litochoro) and there is a landscaped car park. There is also the spring of the river Enipeas. It operates all year round in Prionia refreshment and restaurant. Most of the route takes place in the forest. The trail is very well maintained.
