Riglos: Mallos, Hiking Trails and Romanesque Heritage

The Mallos de Riglos define the town’s landscape. Their large, vertical or rounded walls of rock or conglomerate stand alongside signposted hiking trails and climbing routes. There are also viewpoints, Romanesque landmarks and two celebrations held on set calendar dates. You can plan your visit to Riglos around different interests: landscape views, trails, climbing activities or cultural history.

Rocky Landscapes and Viewpoints

The Mallos de Riglos are reddish geological formations and are characteristic of the Hoya de Huesca. Iron-rich materials give some of the Mallos their reddish hues, which intensify at sunset. The geological formations are protected as part of the Mallos de Riglos, Agüero and Peña Rueba Natural Monument. Two different viewpoints offer views of the landscape: from the Mirador de Espinalba, you can see the Reino de los Mallos and the Río Gállego, while the Mirador de los Buitres offers panoramic views of the Mallos de Riglos.

The Mirador de los Buitres has parking, a ramp leading to the viewpoint, and tactile signs in Braille with raised illustrations. The viewpoint has been adapted for people with reduced mobility or visual impairments. A warning about the access route was in place in January 2025; check current access conditions before your visit. The Mallos are also home to one of Europe’s most significant griffon vulture colonies. The ARCAZ Bird and Scavenger Interpretation Centre in Riglos has a glazed observation point and video cameras, but is currently closed until further notice.

Hiking Trails and Train Journey

Two signposted hiking trails start in Riglos: the Circular Mallos de Riglos and the Camino del Solano. On a circular hike that starts and ends in Riglos, the route passes the Embalse de La Peña and the Foz de Escalete.

The Tren Geológico del Prepirineo combines a ride on the Canfranero with stops, hiking sections and environmental interpretation by specialist guides. The tour’s landscapes include the Mallos de Riglos, the Foz de Escalete and the Embalse de La Peña. If you are planning this journey, check current dates and availability in advance. The Canfranero can also take travellers from La Peña to Riglos via the Río Gállego; check the timetable when making specific plans.

Climbing and Romanesque Heritage

Around 200 climbing routes have been established in Riglos, most of them highly challenging. Keep this in mind if you are considering making climbing a focus of your trip: the figure describes the area, but does not guarantee a particular route for every experience level. The “Vía ferrata Riglos | Cubilillo os Fils” via ferrata runs alongside the Mallos de Riglos. As you climb, iron rungs heighten the sense of verticality and give the route its distinctive character. Check current conditions before setting out on a specific route.

At the entrance to Riglos stands the 12th-century Romanesque hermitage of San Martín. The parish church of Nuestra Señora del Mallo is home to the two Romanesque images of the Virgin, Virgen del Mallo and Virgen de Carcavilla, which are venerated there. Riglos’s Romanesque heritage can thus be found both in the hermitage and in the veneration of the two images of the Virgin.

Festivals in Riglos

San Sebastián is celebrated in Riglos on 20 January; the Virgen del Mallo festival takes place on 1 June. If either date is important to your travel plans, check the event details in advance. This lets you consider the festival dates as specific points in time alongside the landscape and cultural attractions described as available year-round.
