The Mining Railway Trail is part of the Sierra de la Demanda Greenway and follows the old railway line that linked the iron mines with Burgos. The history of the old Sierra de la Demanda mining railway is closely linked to the iron exploitation in this area. Built by the English company The Sierra Company Limited, it began operating in 1901 to transport ore to Burgos and from there to the Basque steelworks, although it never became profitable and closed in 1910. Its tracks were dismantled in 1947, leaving the route unused for decades. At the beginning of the 21st century, the route was reborn as a greenway, part of the Natural Trail Network, and since 2004, it has been an ideal path for hikers and cyclists.

The region is rich in natural beauty and historical sites. You can cycle through impressive forests of junipers, oaks, beech, and pine, especially vibrant in autumn. Notable natural features include the clear rivers like the Arlanzón, and the nearby glacial Puerto del Manquillo. The Neila Lagoons – San Francisco Viewpoint loop offers stunning views of the glacial lagoons. The San Millán Peak (2,133 m) is the highest summit in the park, offering breathtaking panoramic views.

The Sierra de la Demanda offers a spectacular display of colors, especially during autumn, making it a beautiful time for cycling. However, given the region's altitude (over 1,000 meters), spring and early summer also provide pleasant conditions before the peak heat of summer, and the forests are lush. Always check local weather conditions before your trip, as mountain weather can be unpredictable.

A bike light is essential for any unlit open tunnels. It's also advisable to come prepared with your own equipment, as dedicated touring bike services in San Millán De Lara itself are not widely available.
