Foz de Lumbier Circular Trail

You'll find parking available at the main entrance to the Foz de Lumbier Natural Reserve. From there, you can easily access the start of the circular trail.

Yes, dogs are generally allowed on the Foz de Lumbier trails. However, as it's a Natural Reserve and a Special Protection Area for Birds, it's crucial to keep your dog on a leash at all times to protect the wildlife, especially the nesting griffon vultures.

Spring and autumn are ideal for jogging this trail. The weather is usually mild, and the natural scenery is at its most vibrant. Summer can be very hot, so if you go then, start early in the morning. Winter offers a different, quieter beauty, but some sections might be muddy or slippery.

No, there are no entrance fees or permits required to access the Foz de Lumbier Natural Reserve or to jog its trails. It's freely accessible to the public.

The terrain is quite varied. The initial section through the gorge, following the old railway line, is generally wide, flat, and has a firm, pressed surface. After this, the circular route climbs into the countryside with narrower, unpaved sections, gravel, and some rocky paths. Good jogging shoes are recommended for the varied surfaces.

The trail offers several unique sights. You'll jog through two dark tunnels of the old 'Irati' railway line, which was Spain's first electric passenger train. The dramatic limestone gorge itself, with its towering cliffs, is home to hundreds of Eurasian griffon vultures, which you can often see soaring overhead. You can also find the ruins of the 16th-century Foz de Lumbier (Lumbier Gorge) and the Puente del Diablo (Devil's Bridge).

Yes, the Foz de Lumbier Circular Trail utilizes sections of other official routes. It covers 100% of the 'Foz de Lumbier' trail, and also passes through significant portions of the 'Vía Verde del Irati' and the 'Foz de Lumbier (ruta corta)'.

While the main circular trail is moderate, there's a specific side path leading to the ruins of the Puente del Diablo. This path is notably rocky, clings to the rock face, and can be slippery, with fixed chains for support. It offers impressive views directly between the narrow gorge walls and is a more adventurous detour for those seeking an extra challenge.

The initial section through the gorge (the 'Paseo Corto') is wide, flat, and very easy, suitable even for beginners. However, the full circular route (the 'Recorrido Largo') includes climbs and varied terrain that is rated as moderate, requiring a reasonable level of fitness. Beginners might prefer to stick to the gorge section or be prepared for a more challenging second half.

For jogging the Foz de Lumbier Circular Trail, you should bring appropriate trail running shoes, water, and a headlamp or flashlight for the tunnels (especially the longer one). Depending on the weather, layers of clothing are advisable. Don't forget binoculars if you want a closer look at the vultures!
