Winter road trips can be more than a simple commute from point A to point B: they’re an opportunity to uncover landscapes dawned with frost or shrouded in fog that often go unnoticed by those who hustle through traffic lights and urban bustle. When the cold quiets cities and tourists dwindle, Spain offers surprises for travelers who dare to take lesser-used highways. Among them, a northern corner stands out for defying the usual: a road that passes through a cave to reach a small Asturian village.
In the municipality of Ribadesella, beside the Sella river, lies Cuevas del Agua, a village with just over a hundred residents that is accessible only through La Cuevona, a natural cave more than 300 meters long. Unlike a conventional tunnel, the passage was not carved by humans; it follows the course of limestone formations carved by water over millions of years. Inside, stalactites, stalagmites, and rock columns accompany visitors, creating an underground landscape that is as surprising as it is impressive. The road that traverses La Cuevona allows travel by car or on foot, though many choose to stop and walk the stretch to savor the cave’s details at a slower pace. Its singularity also draws hikers and the curious who want to plunge into the cool interior and enjoy the place’s special acoustics.
A Safe and Accessible Experience
Despite its narrow width, the road remains bidirectional and sees a steady flow of vehicles. To ensure safety, regulations require turning on low-beam headlights before entering, and along the route discreet lighting points have been installed to aid visibility, though there are shadowy zones that demand caution. Informational panels and a small parking area at the entrance allow visitors to leave their cars and explore the cave on foot, a choice increasingly popular for those seeking a calmer, more contemplative experience. Exiting at the southern end delivers an immediate contrast: the humid, dark interior of the cavern gives way to brightly colored houses and traditional granaries (hórreos), elements that define the Asturian rural landscape. Cuevas del Agua preserves several old mills and signposted routes that let you explore the surroundings. The most popular is the Ruta de los Molinos, also accessible by bicycle, offering a stroll through the history and nature of the municipality.
@brus_siberianhusky Ruta de los Molinos, Cuevas del Agua, Ribadesella A very beautiful route to do with kids and your dogs. I’ll tell you a bit: it runs along the Sella river and you slowly venture into lush, incredibly pretty forests; to reach the village of Cuevas you have to go into a huge cave of almost 300m (La Cuevona), which is the only access. Incredible, right? We parked before the cave and crossed it on foot because it’s Definitely worth it; once it’s over we continue through the village, which I found super picturesque and very charming, and it’s always a good idea to end a route with a drink at the little place at the entrance. From there the route is well signposted and you can see various water mills until you reach Tresmonte; there you have the option to return by road or go back the same way. For us this was the best option, as you get to see the route from another perspective. Want to know a bit more about the mills? Mills were essential community facilities for farmers where they ground their cereals (corn, barley) to obtain flour that would later become the bread at home. Many of them were built by the neighbors for common use, while others belonged to owners who charged for use by grain (the maquila). In Asturias, given its geographic setup, a large milling industry developed and flourished with maize cultivation, introduced from the Americas, beginning in the 17th century. Cuevas – Arroyo Ginestral del Castiello – Tresmonte. Municipality of Ribadesella. Duration 2.5 hours. We paused along the way, took photos, and even stopped to eat. The information panel at the village entrance says 4 hours, but that seems a long time to me.

The fame of this place as the only village in Spain accessed by passing through a cave has turned Cuevas del Agua into a small tourist phenomenon. Located less than ten kilometers from Ribadesella and a short distance from the prehistoric Tito Bustillo caves, La Cuevona has become a must-visit destination for those who enjoy different routes, charming roads, and experiences that blend adventure, scenery, and natural heritage.
