Liérganes: Hiking Trails and Cultural Heritage

Liérganes lies at the foot of the two small hills of Marimón and Cotillamón, known locally as “las tetas de Liérganes” (“the breasts of Liérganes”). The town’s historic ensemble was designated a site of national historical and artistic interest in 1978 and features valuable 17th- and 18th-century Neoclassical architecture. This offers two distinct areas of focus when planning a stay: the landscape along the Río Miera and the town’s architectural and cultural history.

Hiking Trails and Landscape along the Río Miera

Liérganes’ hiking trails wind through karst landscapes and along the densely wooded banks of the Río Miera. The Circuito por los Picos de Busampiro circular route offers panoramic views of the Liérganes valley, the central Cantabrian coast, and the steep limestone formations of the upper Miera Valley. The route therefore takes in both the valley and the coastal and mountain landscapes.

The short hiking trails in the middle Río Miera basin are marked with the characteristic white and yellow trail markers and are approved by the Federación Cántabra de Montañismo. Check local trail conditions before setting out.

The listed routes vary considerably in length and duration. The Mercadillo Route is 1.5 kilometers long and takes approximately 25 minutes. It connects Mercadillo or Marqués de Valdecilla squares with Vitote, San Pantaleón, and the Puente Mayor. The monumental route covers 4 kilometers and takes about an hour; it passes Baroque and Neoclassical architecture, traditional Montañés manor houses and Indianos’ palaces, as well as churches, chapels, hermitages, a bridge, and a mill. A longer hike is the PR-S 25 Ruta de los Pozos de Noja: it runs from Liérganes to Rubalcaba, is about 18 kilometers long, takes approximately 5 hours and 15 minutes, and reaches a maximum elevation of 850 meters. Check local trail conditions for this route as well.

The Pozos de Noja are two small artificial reservoirs south of the municipality, on the border with Miera. They were the origin of the electricity company Electra Pasiega, which supplied Liérganes and other towns in the region with electricity. The lakes’ history adds an industrial dimension to the landscape.

Cultural History and Townscape

The Ecomuseo-Fluviarium de la Montaña y Cuencas Fluviales Pasiegas is located in Liérganes and explores the natural and ethnographic heritage of the Pasiegos and Eastern Mountains and their river basins. Aquariums, replicas, and exhibitions bring together science, nature, and tradition. The legend of the Hombre Pez is also part of the intangible heritage of Liérganes and Cantabria, and is considered a local tourist attraction.

The La Leyenda del Hombre-Pez audio guide route, described in 2025, includes 17 information points in the historic town center and two more in nearby Rubalcaba. Check whether the audio guide route is available before your trip. The Centro de Interpretación del Hombre Pez is housed in a restored mill dating from 1667 in Mercadillo. It contains two mill wheels for grinding corn and one for wheat. If you plan to visit the Fluviarium or the interpretation center, check the latest visitor information beforehand.

The historic center of El Mercadil includes the Palacio de Rañada, also known as Cuesta-Mercadillo. A prominent landmark on the monumental route is the Puente Mayor de Liérganes: construction began in 1587 to a design by master builder Bartolomé de Hermosa, and the bridge was inaugurated in 1606.

Other buildings include the church of San Pedro ad Víncula, one of the few Renaissance religious buildings in Cantabria. Construction began in 1591 on the foundations of an older Romanesque temple; its remains are still visible in the apse area. The church of San Pantaleón preserves features of the Romanesque tradition. Some authors date it to the second half of the 13th century; in the 15th century, the original building was expanded into a three-aisled church.

The history of the thermal baths can also be traced through time: the Liérganes spa was built in 1862, while the healing properties of the so-called Fuente Santa had been known much earlier. The spa is surrounded by a three-hectare park with numerous trees, including a 32-meter-tall beech, a horse chestnut, and a magnolia, which were included in the Cantabrian catalog of notable trees because of their beauty and size.
