LA BLANCA CIRCULAR ROUTE
Access A and D
Arguedas – “Castildetierra” –Polígono de Tiro perimeter track – “El Paso” Carcastillo (approx. 44 km).
This route can be done in either direction. If starting from Arguedas, take the narrow road leading to Bardenas and the Information Centre. At the high point of Aguilares we have two options; either continue by road to the gates of the military barracks or take a short cut along a track that takes us directly to the Castildetierra “cabezo”. Both options take us to Castildetierra. We continue circling the military zone along the perimeter track. When we come to a signposted junction, we follow signs to Carcastillo (if we wish we can also do the complete loop of the military zone). The route heads up to La Blanca Alta; on one side we’ll see the well-known hills, Pisquerra, Rallón, Ralla..., and on the other, the landscape is dominated by the high points of El Plano, notably, Estroza and Cornialto.
In el Paso, the natural gateway to the Bardenas mention must be made of the Bardena Shepherd Monument. Following signs to Carcastillo, we come out onto the NA-128, which takes us to the village.
EL FERIAL RESERVOIR FROM NTRA. SRA. DEL YUGO HERMITAGE
Access E. Ntra. Sra. del Yugo Hermitage – “El Ferial reservoir”–N-121 road (approx. 18.3 km; 23.3 km from the Arguedas road).
To reach the hermitage take the road leading to the Senda Viva Nature Park. Before reaching the theme park, a turning takes us to the hermitage, Nuestra Señora del Yugo. This well restored 17th century construction has great traditional importance for the villages of the area. Its location, placed atop a sierra provides an excellent panoramic view of the Bardenas.
Near the hermitage, in a small hill, we take a track which branches off. At the junctions, follow signs to the Ferial reservoir. The route crosses the areas of Landazuría and the Agua Salada ravine before coming to the reservoir and the Ferial Services Building (restaurant open Friday to Sunday) which is located on its banks.
Then, to avoid going back the same way, we can carry on towards the N-121 road (signposted) along the Caparroso wind farm track.
PLANA DE LA NEGRA AND SANCHO ABARCA SANCTUARY
Access B. NA-125 road (Tudela-Ejea) – “Plana de la Negra”– Sancho Abarca Sanctuary (approx. 38.2 km,round trip).
The route starts from a track branching on the right from kilometric point 17.3 of the NA-125 heading to Ejea. The Sancho Abarca Sanctuary is signposted.
On the return journey follow signs to the NA-125. During the ascent up to the Plana de Alfarillo the track has an uneven surface so precaution must be taken, especially with lower lying vehicles. Another short rise leaves us in the high plain of La Negra. We skirt around the edge tracing the boundary between Navarre and Aragón. The landscape of the Bardena Negra is made up of cultivated plains, inclines and ravines which are populated with aleppo pine and kermes oak plantations. The final stretch, which transits Aragonese soil takes us up tothe Sanctuary of Sancho Abarca. The views are exceptional. The same route is taken for the return journey.
