The Place of Natural Interest corresponding to the River Llobregós Valley is located in the northern part of the comarca (local district) of La Segarra (Spain), in the triangle between the villages of Sanaüja, Biosca and Massoteres. The green area next to the River Llobregós Valley is a perfect place for following walking or mountain bike routes and enjoying little known and very fragile natural settings.


The part of the Llobregós Valley included in the PEIN is an area with truly unique characteristics. Its interest lies in both its geological form and its vegetation, with the latter including a number of very fragile and vulnerable species. The total area is about 1190 ha and includes the mid-course of this river, which flows through the municipal districts of Biosca, Massoteres and Sanaüja. This is one of the most characteristic gypseous zones of the Central Catalan Depression and also one of the best preserved.
