Oja Green Trail

Stage 1, Casalarreina - Santo Domingo de la Calzada

  • 4 h 30 min
  • 12.4 km

To reach the beginning of the Green Trail, from the bridge over the Oja River in Casalarreina go towards Logroño down the N-232. After about 300 metres, turn right and take the road to Zarratón (LR-311). Before reaching the ring road, take a soil agricultural path on the right that leads between two fruit orchards with wires. The path crosses the ring road and, on the other side, you can see an elevated water deposit, a unique construction with brick arches. From here the green trail is paved and you will advance on a stretch that you will share with cars until you reach a wide poplar grove. After the grove, cross a path and you will find an even better ground, as the stretch is exclusive for pedestrians and bicycles The landscape on both sides is agricultural and, on the right, there is a row of black poplars and alder trees that results from the pools that drain the Oja aquifer. After a few kilometres, cross a paved path that leads to Castañares de Rioja and, a little after, there is an area with benches and tables in the old railway stop. For a short stretch, the pavement of the green trail disappears, on a section shared with cars that runs along agricultural warehouses of the town. Return to the straight well-defined path among the croplands of the Oja River flood plain. Cross a channel, then the LR-309 to Bañares, and after 100 metres a path that was a Roman road and part of the Way of Saint James until the 12th century. Little after you will pass next to the remains of the Bañares station. Continue for 4 km to reach the LR-203. At the end of this stretch you can see some isolated holm oaks. Their presence reminds us of the large holm-oak woods that populated these plains before the historical clearing of land for agriculture. After crossing the LR-203, you will pass under the ring road of Santo Domingo de la Calzada. After 1 km, you arrive to the town on the N-120 road, which crosses the city centre. In Santo Domingo de la Calzada appears another route included in the Footpath Network of La Rioja, the Way of Saint James, that crosses the town and that comes from Nájera and goes to Grañón, in La Rioja.

Santo Domingo de la Calzada

The city is a beautiful stop on the Way of St. James. It is linked to Santo Domingo, who was born in Vitoria, and to his building work on the Roman road.

The bridge spanning the River Oja, which helped pilgrims on their way, also contributed to the city's development.
