The Church of San Martín in Huerta de Arriba combines a Romanesque apse with a neoclassical nave built in 1729. Inside, the main altarpiece stands out, in a neoclassical style with Baroque influences. It is a good example of how different architectural styles coexist in a single rural church.

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 railway crossed this port through a tunnel. When making the greenway, the original route was not recovered, so the arrival and departure of the port are two very steep slopes. Most panniers make them by pushing the bike.
