Although all indications suggest that the original route of the Via Augusta followed the current N-340 highway, an alternative, less trafficked, and more rural route is proposed, skirting the westernmost part of the Olèrdola Natural Park.
From the Vilafranca train station, the route heads towards the Moja road, where it utilizes the cycle path that leads to Moja (Olèrdola).
In Moja, the route passes through the church square, right next to the 10th-century Moja tower and the Romanesque chapel of Sant Cugat de Moja. Nearby are notable buildings such as the Modernista-style Casa Barber and the Noucentista-style Casa Batlle. Shortly after leaving Moja along the Penyafel road, the route reaches the farmhouse of the same name, a former castle transformed into a farmhouse in the 17th century. Right next to it is the 11 th-century chapel of Santa Maria de Penyafel. At this point, the gravel route continues along the Penyafel road to Santa Margarida i els Monjos. Located between the farmhouse and the chapel, a trail begins with some fairly technical sections due to large slabs of stone, roots, and a few small steps where mountain bikers will need to be careful.
Once inside Olèrdola Natural Park, the route follows tracks through pine forests bordering vineyards, before descending again towards Santa Margarida i els Monjos, entering via the cemetery road. The route ends at the Santa Margarida i els Monjos train station. To continue to the next stage, just past the cemetery, turn left at the Uniland cement factory.

The oldest part of this architectonic complex is the circular tower, which probably dates from the 12th century, which corresponds to the remains of the birthplace of Raymond of Penyafort (1185-1275). In addition to this medieval tower, the complex includes various buildings erected as of the 17th century, which were a Dominican convent up until the confiscations of Mendizábal in 1836. Afterwards, the building passed into the hands of the bourgeois Puig i Llagostera family, who made it their summer residence. This building has had several owners over the decades, who have implemented various improvements and projects, until in 2001 it became the property of the municipality.
The Centre for Interpretation of Republican Aviation and Air Warfare is a museum related to aviation and the civil war that is located beside masia del Serral which had housed the republican airfield of els Monjos that was part of the Vesper de la Gloriosa (Hive of the Glorious).
Next to the centre there is the old air raid shelter, whose two entrances and three ventilation chimneys can be seen. The presence of this shelter is related to the existence of the airfield. It is about 10 m deep and has a capacity for about 120 peoples.
The construction known as Foix Mill (formerly Macià mill) is what remains of the old medieval flour mill, which took advantage of the water carried by the Foix river to mill grain. The entire exterior structure of the mill is preserved, as is part of the pool where the water accumulated.
The building, owned by the municipality, is the headquarters of the Foix Mill Historical and Natural Interpretation Centre, Nature Classroom and Botanical Garden, with native species, where educational activities are carried out for school children and the general public on environmental and natural issues.
A Romanesque chapel situated atop a small hill to the east of the municipality, on the edge of the mountains where the vineyards meet, near the village of Moja. The hermitage of Mare de Déu de Penyafel has been a site of pilgrimages and gatherings, sometimes even organized by neighboring towns. Located near the Penyafel farmhouse and built slightly higher up, both buildings are visible from almost anywhere within the municipality.
The Penyafel chapel is already mentioned in a document from 1131 under the name "Penna Fedel." Inside, the image of the dark-skinned Mare de Déu de Penyafel is venerated, and until the early 20th century, it housed two 15th-century Gothic altarpieces.
