The best MTB trails around Olvan

Splendid place a few km from Berga. From there, the old lane leads to Cal Rosal.

A very beautiful path from the Pedret bridge. Some of the sections are quite dark due to the length of the tunnel, but it can be cycled smoothly bit by bit.

Dating back to 1286, this bridge helped improve communications between Berga and the monastery of Sant Pere de la Portella. At first the bridge was made of wood, but a short time later it was rebuilt in stone and in the Gothic style. The central ogive as seen now was added in the 15th century. This bridge is a magnificent example of medieval "cornered" or "donkey's back" bridges, with its central part raised, thus allowing a wider central arch that allows greater water flow. Three smaller ones are added to the sides, two to the right and one to the left, semicircular, somewhat irregular and lowered. The bridge has undergone repairs and reconstructions over time due to floods, and in the 17th and 18th centuries the road was paved with boulders and a stone railing was added.

Documented in 1095 and under the rule of the counts of Cerdanya, this fortification is built on the ancient remains of an Iberian defensive construction. The castle was considerably enlarged during the 13th century, connecting its walls with those of the city of Berga. Scene of conflicts and assaults, it was rebuilt again in the 18th century and again in the 19th century, due to the fact that Berga was the center of the Carlist wars.

The church of Sant Vicenç d'Obiols is a pre-Romanesque construction of the 10th century located in Obiols. Around the temple there is a necropolis of tombs dug directly into the rock.

The Pedret Bridge is a bridge of about 80 m in length, of medieval origin, over the Llobregat river. It served to unite the town of Berga with the church of Sant Quirze de Pedret and is documented in the year 1286. It is in the Gothic style and consists of four arches, although initially it had five, of unequal sizes: the central arch is pointed and much higher than the others, the rest are smaller, two semicircular, lowered, and a third pointed arch. Near the bridge, and dug into the rock, there is a series of rounded holes that correspond to the sockets of the wooden beams that supported an old Romanesque bridge. It is advisable to go up the old path nearby that leads to the church of Sant Quirze de Pedret, and visit it. It is one of the best preserved examples of pre-Romanesque religious architecture in Catalonia, built in the Carolingian period (9th-10th centuries).

Near the Peirota tunnel is the Peirotes or Vilarrassa bridge, made up of a structure over 50 meters long and approximately 3.75 meters wide.

This church is a Romanesque construction from the middle of the 12th century. I think the original altar is in the MNAC in Barcelona. This is a place to see on a hike or mountain bike in this area.
