Castroserna De Arriba lies on the banks of the San Juan River. The riverside landscape, limestone houses and traces of historical culture come together in themes that can help you plan a trip here. Two perspectives are useful when making your choices: the village’s character, with its church and Potro de Herrar, and the different routes, with their destinations, lengths and trail features.

Architectural history and riverside landscape

The houses of Castroserna De Arriba are irregularly arranged, built of solid limestone and often decorated on their facades with sgraffito, typical of the region. Next to the riverside park stands a well-preserved Potro de Herrar made from local juniper wood. The Iglesia de Nuestra Señora del Rosario offers another facet of the area’s architectural history: it is originally Romanesque and was extensively remodelled later. The houses, ethnographic landmark and church each represent different aspects of the area’s cultural history.

The surrounding area also offers a variety of landscapes. Dense stands of juniper and holm oak grow at higher elevations. Along the riverside path from Castroserna De Arriba to Castroserna De Abajo, griffon vultures nest on the cliffs on both sides of the river valley, which grows increasingly narrow. The woodlands in the higher surroundings and the nesting sites along the riverside path are two distinct natural features of the area.

Routes by destination and trail type

The easy Ruta del Molino Blanco starts opposite the ruins of the Marqués’s house and follows the river to an old grain mill. From there, the route continues past limestone cliffs to the Cueva del Horcajo. The cave served as a refuge for shepherds and farmers. The mill, cliffs and cave provide specific destinations along the route.

The Ruta del Río San Juan, Circuito 2, is a linear route just over five kilometres long. It has very little elevation change and is suitable for families. An information board about this route is located near the parish church in Castroserna De Arriba.

Another hiking trail connects Castroserna De Arriba with Prádena, is about eleven kilometres long and passes the ruins of Matandrino. A much longer option is the 32.43-kilometre circular route Las tierras del Marquesado de Castroserna. It goes through Castroserna De Arriba, Castroserna De Abajo, Villafranca, Perogordo and Serna de Velosillo.

When comparing the routes, distance is not the only factor: the Ruta del Molino Blanco leads to a mill and a cave, while Circuito 2 combines a linear trail with very little elevation change and suitability for families. The route to Prádena passes the ruins of Matandrino, while the circular route includes five villages. This makes it possible to distinguish the routes by their respective destinations and features.

A historic pastoral tradition

Agriculture is also part of the area’s history. Historically, the limestone plateaus provided high-quality pasture used by Churra sheep to produce high-quality suckling lamb. The historical connection between the plateaus, pastoral farming and suckling lamb adds another aspect of local history to the architectural and riverside themes.
