You may not see this bridge if you pass quickly and are not paying attention. In addition to its beauty, it is also interesting for its location, since it is located next to the mouth of the Isábena river with the Ésera river.

It is a beautiful town that can be easily reached by pedaling from Secastilla. There are many tracks in the area, which also connect with the reservoir, although if you have to return, make sure to save your strength, since you will have to climb back up. In addition to walking through its quiet streets and discovering corners such as its oil mill, we recommend that you visit the Roman site of Labitolosa (next to the town) and the incredible hermitage of San Román, located in a location that will not leave you indifferent.

The historic center of Graus is a jewel of traditional architecture. Not in vain has it been declared a set of artistic-historical interest for its main square, arcades, cobbled streets and stately homes.

The city of Graus has been declared an artistic-historical complex and its main square is a good example of why. The stone arches, the painted facades of the manor houses and the buildings from different eras create a charming traditional atmosphere to stop and have a drink (don't miss the opportunity to taste the famous Graus sausage).
