Liérganes, just over half an hour from Bareyo, is worth visiting for its historic centre of El Mercadillo, the legend of the Fish-Man with its interpretation centre by the Puente Mayor, the thermal spa that once attracted royalty, and the hiking trails up to the Busampiro peaks.
Less than thirty kilometres from the coast, Liérganes breaks with the beach-and-cliff image usually associated with Cantabria. Here the valley takes centre stage: the Miera river runs through the village under stone bridges, mansions bearing coats of arms line up alongside arcades, and twin mountains watch over the horizon. It's a change of scenery that works well as a day trip from Bareyo, especially combined with Cabárceno or Santander, both a stone's throw away.
But what has made Liérganes famous beyond Cantabria is a legend: that of the Fish-Man. And the curious thing is that it's not just folklore — it starts with a real villager who vanished in the 17th century, whose story is still told, almost with devotion, next to the bridge where tradition says he was last seen. Between that legend, a century-old spa and a handful of hiking trails, a couple of hours in Liérganes fill up effortlessly.
What to see in El Mercadillo, Liérganes' historic centre
Liérganes' historic centre, known as El Mercadillo, is a listed historic-artistic site and can be walked in a little over half an hour, though it's worth taking it slowly. The Palacio de Rañada, the parish church of San Pedro Ad Víncula, the church of San Sebastián and the houses of the Setién and Cañones families make up the core of mountain-style mansions that give the district its name. On either side of the river stand the new bridge and the Puente Mayor — Roman in origin, according to local tradition — which is also the central setting of the legend that made the village famous. It's worth checking the opening hours of the Liérganes tourist office before visiting, as they vary by season.
The legend of the Fish-Man and its interpretation centre
Legend has it that Francisco de la Vega, born in Liérganes in 1660, threw himself into the Miera river as a young man and vanished for years, until fishermen claimed to have found him, turned into an amphibious creature, in the bay of Cádiz. Having lost his reason and speech, he was returned to his village, where tradition says he died years later without recovering either. Whatever truth lies within it, the legend has become the town's identity: a bronze statue commemorates the Fish-Man beneath the Puente Mayor, and an old flour mill by the river houses the Interpretation Centre dedicated to his story, with panels and recreations explaining the myth and its historical context. Admission costs one euro and is free for children under seven.
The spa that attracted royalty
The waters of the Fuente Santa in Liérganes had been known for their medicinal properties for centuries when, in 1862, the spa opened that turned the village into a rest destination, with visitors as distinguished as Alfonso XIII. Today the complex, surrounded by a three-hectare park with century-old trees, combines two hotels, a restaurant and a range of thermal circuits and treatments, from mud therapy to Eastern-style massages. You don't need to be a guest to come and see the building and its grounds, though the thermal circuits do require booking in advance.
The Busampiro peaks and hiking trails
Anyone wanting to stretch their legs before or after visiting the village has the Busampiro peaks close by, twin summits popularly known as "Liérganes' breasts" that serve as a visual landmark across much of the valley. The trail up to them starts in the village itself and offers wide views over the Miera valley and, on clear days, the bay of Santander. It's a demanding route in its final stretch, but requires no technical experience, and rewards you with scenery very different from what you see on the Bareyo coast.
What you need to know
Liérganes is just over half an hour by car from Bareyo via the A-8 and the CA-142, and pairs easily with a visit to Cabárceno Park, barely ten minutes away. The historic centre can be seen well in two to three hours; add the Fish-Man Interpretation Centre and a walk up to the Busampiro peaks, and it's worth setting aside half a day. The best time to go is from spring to autumn, when the valley is greener and the hiking trails can be enjoyed without mud. If the spa is part of the plan, book the thermal circuits in advance, especially at weekends.
"In Liérganes, every corner of El Mercadillo still seems to echo with the legend that made it famous"
Liérganes is the kind of trip worth keeping in mind when you want a different kind of day without straying far from the coast: a village with history, a legend passed down from generation to generation, and a green valley that contrasts with the beaches of Trasmiera. If you liked our guide to the best spas in Cantabria, add Liérganes' to the list: it's one of the oldest in the region. From Villa Camino and Villa Monte, the two Bareyo Residences villas, these inland getaways are a stone's throw away for anyone looking to combine beach and mountains in the same stay.
