Biosphere reserve, Ordesa y Vignemale
This tour will give you the opportunity to contemplate three magnificent adjoining valleys near Ordesa Valley, all listed as Biosphere reserves: Bujaruelo, Otal and Ordiso Valleys.
The course of the Ara River, the only river in the Pyrenees left untouched by human activity, will accompany us along the way.
Various stops will be made along this route, a paradise for lovers of flora and fauna.

Bujaruelo
Once a major meeting point for pilgrims who wandered through its lands as well as a key point for grazing, Bujaruelo is considered one of the most emblematic valleys in the Pyrenees’. The beautiful Romanesque bridge, the ruins of St. Nicholas Chapel and the renovated pilgrims’ inn attest to its importance.

Otal valley
Typical Pyrenean glacial valley right at the foot of Sierra Tendeñera. This is a natural habitat for Marmots and other rottens, who coexist peacefully with indigenous livestock.

Ordiso valley
Here, you will be able to contemplate Ara River’s spectacular gorge. This valley is especially noteworthy for its characteristic flora. Among the most unique, outstanding species are the Lys flower, Pyrenean violet, or the King’s Crown flower, all of which are indigenous to the area.
The Vignemale, one of the most important peaks in the Pyrenees, awaits us at the end of our journey.
