Arlanzón

Overview

Arlanzón is a village of a few hundred people 20 km east of Burgos, and the place where the Vía Verde de la Sierra de la Demanda leaves the valley floor for the mountains. The greenway runs 52 km east to Monterrubio de la Demanda on the trackbed of an abandoned mining railway, and it starts here, at around 999 m on the river the village is named after.

The municipality is much bigger than the village. It covers 77.74 km² and had 425 registered residents in 2025, spread across Arlanzón itself plus Agés, Galarde, Santovenia de Oca and Zalduendo, with the outlying settlements of Villalbura and Villamórico. Two of them, Santovenia de Oca and Agés, sit on the Camino Francés. The Sierra de Atapuerca, listed by UNESCO in 2000 and rising to 1,085 m at the Cumbre de San Vicente, lies just outside the municipality, north of Ibeas de Juarros on the Burgos road.

Nobody comes to Arlanzón for monuments. You come because it is a cheap, quiet base a short drive from the Atapuerca excavations and from Burgos, with 52 km of graded, traffic-free trail starting in the municipality. The patronal fiesta is on 29 September for San Miguel Arcángel, with a sung mass and a procession through the streets, and since the 1990s there has been a second, purely recreational fiesta in the first week of August aimed at the families who return for the summer.

History

Arlanzón appears in the written record early. Land exchanges involving the village were being drawn up as legal documents by 935. The area was settled during the Middle Ages by Vascones, and in the 12th century traders at Arlanzón’s markets petitioned the Castilian king for the right to speak Basque there. The name turns up in the Poema de Mio Cid, spelled “Arlançón”.

What the medieval documents mostly concern is water. In 1074 the infantas Urraca and Elvira handed the church of Santa María, the village around it and its mills to the bishop of Burgos, and in 1189 Alfonso VIII passed the mills to the Cistercians. Milling rights on the Arlanzón stayed worth arguing about for centuries afterwards, and the village still has a street called Camino de los Molinos, the mill road.

The 20th century did the damage that the disentailments started. Arlanzón held 637 people in 1900 and 315 by 1970, and the count only recovered on paper in 1981, when Agés, Galarde, Santovenia de Oca and Zalduendo were absorbed into the municipality. The mining railway had already come and gone by then, and the trackbed sat unused for most of a century before it reopened as a greenway in 2004. Spain listed Arlanzón at number 1265 in the associated-elements inventory it submitted to UNESCO in 2015 for the extended Camino de Santiago inscription.

Visiting

There is nothing to buy a ticket for. The village, the churches and the trailhead are open at all hours and free, and the only staffed counter is the town hall on Calle Samuel Morse, open Monday to Friday 10:00 to 13:00 and Thursday afternoons 17:00 to 19:00, on 947 421 102.

The greenway is the reason to stay more than an hour. It leaves the municipality heading east and covers 52 km to Monterrubio de la Demanda, crossing Villasur de Herreros, Pineda de la Sierra, Riocavado de la Sierra and Barbadillo de Herreros, with four viaducts and 380 m of total ascent. One tunnel is open to walkers and cyclists; two others are closed, so the route detours around them.

Walkers on the Camino Francés cross the municipality at its northern edge rather than through Arlanzón village. Santovenia de Oca sits on the route and connects to the N-120 by the BU-V-7012. Agés, on the north-western side of the municipality, has the small church of Santa Eulalia in the middle of the village and a bridge traditionally attributed to San Juan de Ortega; a priest’s will of 1 May 972 names the place as Sancta Eugenia de Haggege.

The same place has private rooms and food if the hostels are full of school groups: doubles at €46 and triples at €57 for lodging, cabins for four or five at €80 to €100 a night, breakfast €4, lunch €10 to €15 and dinner €10, all before the 10% VAT. That is the whole of the village’s catering infrastructure in one address, which is worth knowing before you arrive hungry at nine on a Sunday night.

Tips

• Book Atapuerca before you book a bed. Visits to the Sierra de Atapuerca excavations and the CAREX experimental archaeology centre require an advance reservation, taken by phone on 947 421 000 or at reservasatapuerca@fundacionatapuerca.es, Monday to Saturday 09:00 to 17:00 and Sundays and holidays 09:00 to 14:00. Guided visits are sometimes cancelled for weather, so leave yourself a spare day.

• Ride the greenway downhill. The whole 52 km climbs 380 m from Arlanzón to Monterrubio de la Demanda, so if someone will drop you at the far end you get a gentle descent instead of a day of grinding uphill.

• Do not plan a Camino stage stop at Arlanzón village. The Camino Francés crosses the municipality through Santovenia de Oca and Agés, several kilometres north, and walking down to Arlanzón adds distance for no reason.

• Ring the Granja Escuela ahead on 947 421 807 rather than turning up. It is a residential farm school taking school and sports groups, so a booked week can leave nothing free.

• Time a visit to the village fiesta if you want it lively. San Miguel Arcángel on 29 September brings the sung mass and street procession; the first week of August is the newer summer fiesta.

• Drive in on the BU-820 from Ibeas de Juarros. The N-120 Burgos to Logroño road passes through Zalduendo on the northern side of the municipality, not through Arlanzón itself.

• Deal with the town hall in the morning. The counter opens 10:00 to 13:00 on weekdays and only reopens on Thursday afternoons, and the practical alternative is email to arlanzon@diputaciondeburgos.net.
