The Pre-Pyrenees (which constitute the outer ranges of the Pyrenees mountains) and the Somontano region (which lies in the foothills of the Pyrenees ) are the two geomorphic units that mark the transition between the Mediterranean and Atlantic climate zones. This implies the observation of a wide biodiversity of species both in terms of flora and fauna. You may come across species on the same excursion that are many kilometers apart in Europe, such as holm-oak groves (Quercus ilex) together with Scots pine forests (Pinus silvestrys), or rosemary (Rosmarinus oficinalis) together with Pyrenean-violets (Ramonda myconi).

The proposed trails will lead us through a contrast of landscapes, from the arid steppes of the south of the Somontano region to the rocky limestone peaks of the pre-Pyrenees, in less than 50 km. This will allow us to discover four different habitats including steppe, riverbank, the Somontano region, and the Pre-Pyrenees.

• Mediterranean Landscape. Adahuesca
• Harmony in the contrasts. Alquézar
• Oligocene Gypsums and the Barbastro Anticline. Barbastro
• The Estada Diapir. Estadilla - Estada
• Rocky outcrops, tabletop hills and sandstone cliffs in la Clamor Valley. El Tormillo

• River Canyons in the Gulley of the Virgin. Rodellar
• Torreta Hill. Salinas de Hoz
