The Only River in the Balearics
Many people are surprised to discover that Ibiza has a river. And not just any river, but the only river in the entire Balearic Islands: the Santa Eulària River. Sure, it's not the Ebro or the Guadalquivir: it's barely seventeen kilometers long, carries water only during the rainy season, and in summer its bed dries up almost completely.
But for centuries it was the backbone of agricultural life in the municipality of Santa Eulària des Riu, and its course is marked by flour mills, traditional orchards and stone bridges that tell the story of a rural Ibiza that existed long before tourists arrived.
The Route: Puig de Missa as Your Starting Point
The circular route I'm proposing is about eight kilometers and begins at Puig de Missa, the hill that overlooks the village of Santa Eulària with its 16th-century fortified church at the top.
This church, one of the most beautiful in Ibiza, was built with thick walls and arrow slits to serve as a refuge for the population in case of pirate attacks. From the esplanade you have a beautiful view of the village, the river, the river mouth and the sea: the perfect place to start with a general overview.
The Pont Vell
Descend from Puig de Missa along the cobbled path that winds down between white houses with bougainvillea until you reach the river bed. Here you'll pass under the Pont Vell, a stone bridge of Roman origin rebuilt in the Middle Ages, one of the oldest monuments in Ibiza. Cross it and take the path that follows the river upstream.
The Flour Mills
The main attraction of this route is the old water mills that used the river current to grind wheat and barley. Along the way you'll find the remains of several of these mills, some quite well preserved.
The most important is the Molí de Baix, restored and converted into a small ethnographic museum where you can see:
- The original stone millstones
- Water channels and gates
- The wooden mechanisms that operated the machinery
- Traditional agricultural tools
It's fascinating to think that this same technological ingenuity was feeding Ibicencan families for centuries.
The Riverside Canopy
The path along the river is shaded and cool, protected by a gallery of riverside trees including elms, poplars, reeds and brambles. In spring, the banks fill with wildflowers and birdsong is constant.
You'll see blackbirds, goldfinches, hoopoes with their distinctive orange crest and, if you're lucky, a kingfisher diving into the water. It's a surprisingly rich ecosystem for such a small island.
Local tip: this is the perfect route for the hottest summer days. The riverside tree canopy provides constant shade, and the atmosphere by the water is noticeably cooler than anywhere else on the island. Bring a picnic and find a spot by the riverbed to eat.
The Traditional Orchards
On both sides of the river extend the orchards that for centuries took advantage of the water from the riverbed. Some remain in production today, and you'll see plots of orange trees, lemon trees, fig trees and vegetables that local farmers work using the same techniques as their grandparents.
The traditional irrigation systems, with stone irrigation channels and wooden gates, are a precious example of popular hydraulic engineering. In some stretches the path crosses open fields where centuries-old carob trees grow with their twisted trunks and enormous canopies, one of the most emblematic trees of Ibiza.
The Return via the River Mouth
The route completes the circle by returning to Santa Eulària along the final stretch of the river, where the bed widens and flows into the sea near the marina. This last section has a well-maintained promenade that passes through a park where families stroll in the afternoons.
The river mouth forms a small wetland where you can see herons, little egrets and other water birds, especially at dawn and dusk.
