Castarlenas is a town that, unfortunately, was depopulated about fifty years ago. Even so, you can easily reach it by walking from the town of Torres del Obispo, although you will have to be careful if you try to enter its streets, since a large part of its buildings are in ruins, so it is not highly advisable. In addition to an information panel where you can learn much more about this place, you will have excellent views of the Barasona reservoir and the Carrodilla mountain range.

Also called Mondoto Castle, it is a religious-military complex that stands out for the remains of the hexagonal tower of the castle and the hermitage, good examples of Romanesque architecture. The hermitage is dedicated to San Emeterio and San Celedonio and curiously enough, it was actually designed as the first defense mechanism of the castle, since possible attackers had to first cross the place where the monks slept.

Troncedo is a small town and mountain pass that is located at 1,009 meters above sea level in the southeastern end of La Fueva, on top of a hill on the slope of the Sierra del Turón from Graus to the Fuevan hollow, but which is currently along the HU-V-6441 road. The most defining characteristic of Troncedo is its castle, of which only the homage tower remains, which is larger than those of other main castles in Sobrarbe (the castle of Aínsa or the castle of Boltaña), which makes one think in the proportions that it could have in its time of use. Due to the importance of the castle of Troncedo, the antiquity of the place is known, since documents have been found since the reign of Sancho el Mayor (first half of the 11th century) that already testify to the importance of defending the county of Troncedo, Sobrarbe as well as the nearby town of Graus, which was still Moorish. In 1797 Troncedo had 150 inhabitants; currently has about thirty inhabitants. The road from Graus is in very good condition for road cycling, little traffic, good asphalt and steep climbs. On the other hand, on the Trillo side the road can be defined as a paved forest track and has steeper slopes and very tight curves.
