Remains of an old Civil War defensive position, located high on a hill between Monzón and Almunia de San Juan. Accessible via a dirt track, with a short but steep final slope. From the top, trenches, parapets, and some excavated lookout posts are preserved, as well as stunning views of the Cinca Valley and surrounding area. A historic spot, ideal for stopping, taking a breath, and reflecting on everything that happened in these mountains. Highly recommended for MTB or gravel routes in the area.

A group of natural caves located on the slopes of Mount San Caprasio, associated with ancient pastoral, hermitage, and possibly even pre-Christian uses. Some were used as shelters for shepherds or anchorites, and local tradition links them to the primitive cult that gave rise to the hermitage. Relatively easy to access from the track or the hermitage, they are a curious place to explore on foot, with views of the Ésera Valley and an utterly silent environment. They add a mystical and ancestral touch to any route in the area.

A small natural viewpoint located on a stretch of the trail just before reaching the San Caprasio hermitage. It offers sweeping views of the Ésera Valley, the surrounding villages (El Run, Castejón de Sos, Sesué), and, on clear days, as far as Turbón and part of the Posets massif. Ideal for resting after the climb, taking photos, or simply enjoying the silence of the mountain. A perfect spot to recharge your batteries before the final stretch to the hermitage.

A dirt track that ascends from El Run toward the area around San Caprasio, with sections of steady gradient and uneven road surfaces in places. Ideal for MTB or gravel riders with good handling, it offers spectacular views of the Ésera Valley and the Pyrenean foothills. Surrounded by forest and scrubland, it is a challenging but very rewarding climb. Perfect as a connecting section to higher routes in the Benasque Valley or as a symbolic climb for its cultural and scenic value.
