We stopped at the municipal motorhome area in Puente San Miguel, near Santillana del Mar, in October. The car park was moderately busy, but we easily found a space for our 23-foot motorhome. It is next to the railway line, so trains pass close to the parking area, but during our stay it was not particularly noisy and we had a pleasant stop. Unfortunately, the whole area was very dirty and run-down, with clear signs of a lack of maintenance. The biggest advantage is that parking is completely free. The location is also practical for visiting the surrounding area, including Santillana del Mar and the Altamira Museum.
The parking area is beside the River Saja and the local FEVE railway station. According to the municipality, it was designed to accommodate around ten to twelve motorhomes, with facilities for filling drinking water and emptying wastewater. The area is paved and also used by other vehicles, so availability depends on how busy it is. The railway is both an advantage and a disadvantage: although you can hear the trains, the station makes it possible to leave the motorhome parked and travel towards Santander by public transport. The condition of the area was disappointing when we visited, however, and it would benefit from better cleaning and maintenance.
Puente San Miguel is the main settlement of the municipality of Reocín, in Cantabria, northern Spain. Although it is not a major tourist destination in its own right, it has a long history connected with the River Saja, the surrounding agricultural settlements and the development of transport through the region. Its location between Torrelavega and Santillana del Mar also makes it a useful base for exploring the area.
The name of the settlement comes from the historic bridge over the Saja and the nearby Hermitage of San Miguel. The municipality’s historical account records that a medieval bridge and religious building once stood here, alongside a small hospital or lazareto that provided assistance to poor people and pilgrims. The hospital was maintained by the Abbey of Santillana and was still operating in 1701, although it had fallen into ruin by the middle of the eighteenth century. The old bridge connected the settlement with the route towards Santillana del Mar, helping explain the importance of this crossing long before the arrival of the railway.
The remains of the medieval religious building can still be seen near the present-day Ermita de los Nueve Valles, historically associated with San Miguel. The original Romanesque church fell into ruin, and a replacement chapel was built during the first half of the eighteenth century. Later alterations changed its appearance, and only part of the old structure survives. Although the remains are modest, they provide a reminder of the settlement’s medieval origins and its connection with the surrounding villages.
One of the most important historical sites in Puente San Miguel is the Casa de Juntas de los Nueve Valles. On 28 July 1778, representatives of the Province of the Nine Valleys of the Asturias de Santillana met here and agreed to establish the Province of Cantabria. This meeting is regarded as a key moment in the institutional history of the region. The present building is a reconstruction located in Parque de La Robleda, where the annual Día de las Instituciones commemorates the event. The celebration takes place on 28 July and remains one of the most significant dates in the local calendar.
Parque de La Robleda is one of the main public green spaces in the settlement. It contains the reconstructed Casa de Juntas and provides an area for walking and recreation. The park is particularly important for understanding the history of Cantabria because it connects the landscape with the political developments that led to the creation of the province. It is not a large attraction requiring a full day, but it is worth visiting while exploring the town.
Another notable place is the Historic Garden of Puente San Miguel, situated within the private estate of the Sanz de Sautuola family, later associated with the Botín family. The garden is protected as a Cultural Heritage Site in the category of Historic Garden and covers more than seven hectares. Its origins are connected with the botanical interests of Marcelino Sanz de Sautuola, the Cantabrian naturalist and archaeologist best known for his role in the discovery of the prehistoric paintings of Altamira.
The garden contains mature trees from different parts of the world, including American redwoods, metasequoias, horse chestnuts and cedars of Lebanon. One of its particularly notable trees is a eucalyptus planted in 1867. The estate developed over several generations, as the family expanded and maintained the original grounds. Access is restricted because the property is privately owned, and visits require an advance reservation. The municipal website publishes the current arrangements, so it is best to check before planning a visit.
The connection with Marcelino Sanz de Sautuola leads naturally to the nearby Cave of Altamira, one of the most important prehistoric sites in Europe. The cave is famous for its Upper Palaeolithic paintings, especially the bison painted on the ceiling using the shape and relief of the rock to give the animals a three-dimensional appearance. The paintings are thousands of years old and provide evidence of the artistic abilities and symbolic culture of prehistoric communities.
The original cave has very restricted access to protect the paintings, but the Museo Nacional y Centro de Investigación de Altamira includes the Neocueva, a detailed reconstruction that allows visitors to understand the cave’s layout and see reproductions of its most important paintings. The museum is close to Puente San Miguel and provides one of the main reasons to stay in this part of Cantabria.
Santillana del Mar is another nearby destination. Its historic centre is known for medieval stone houses, noble mansions, cobbled streets and the Collegiate Church of Santa Juliana, an important Romanesque building. The town developed around the monastery and became one of the best-preserved historic settlements in Cantabria. Although it is a popular tourist destination, its main streets and monuments can be explored on foot, making it a straightforward visit from Puente San Miguel.
The wider municipality of Reocín also has an industrial history. Mining played an important role in the local economy, particularly the extraction of zinc. The Reocín mine became one of Spain’s major zinc-producing operations, and the activity continued for more than a century before the mine closed in 2003. The mining industry transformed the area, providing jobs and contributing to the development of transport and services. Today, the legacy of that industry remains part of the municipality’s history, alongside its traditional settlements and historic buildings.
Puente San Miguel’s position also makes it suitable for exploring other parts of the Saja-Nansa area and western Cantabria. The River Saja and the surrounding countryside offer walking opportunities, while the nearby towns provide shops, cafés and other practical services. The railway connection is particularly useful for people who want to visit Santander without taking their motorhome into the city.
For us, the free motorhome area was convenient despite its poor condition. We found a space easily, the railway noise was manageable during our stay, and the location worked well for exploring the surrounding area. The main drawback was the lack of maintenance, which made the parking area feel dirty and neglected. Nevertheless, Puente San Miguel is a useful practical stop for visiting Santillana del Mar, the Altamira Museum and the historical sites around Reocín, especially for travellers who value free parking and a nearby railway connection.
