Infernuko errota

Infernuko errota is a restored water mill tucked into the Baztán Valley in northern Navarre, close to the border with the neighbouring municipality of Etxalar. Its Basque name translates as "the mill of hell," taken from the stream running past it, the Infernuko erreka — "the stream of hell." The spot combines history and nature on an easy walk, which is why it draws families with children as well as anyone curious about rural Basque heritage.

How do you get to the mill?

The usual starting point is near the Etxebertzeko Borda restaurant, in the Orabidea neighbourhood, part of the village of Lekaroz. From there, a marked path follows the Infernuko erreka stream all the way to the mill. The walk is short and undemanding: reaching the mill takes about 20 minutes, and the full round trip is usually done in around an hour at a relaxed pace. The gentle terrain makes the route suitable for children and older visitors alike, and since the path simply follows the water the whole way, getting lost is not really a concern.

What will you see along the way?

The walk itself is as much a part of the experience as the mill at the end of it. Along the stream, the path passes a trout farm, a small waterfall, and a striking ravine carved into the rock by the water — details that turn a simple approach walk into a small outing in its own right. The mill itself had fallen into disrepair after years of abandonment before being fully rehabilitated by the Argarate family, who also own the nearby Etxebertzeko Borda restaurant. Today the building looks close to its historical state, set among dense greenery, rock, and the constant sound of running water — a combination often described as enchanting.

What is the history behind it?

The mill dates back to the Carlist Wars of the 19th century, when it served an important role for troops scattered around the area, who came here for flour supplies. For generations, local residents also brought their corn to be ground here, one of the everyday functions water mills fulfilled throughout this part of Navarre. Its most notable chapter came during the Spanish Civil War, when Infernuko errota was the only mill in the area that kept working — operating clandestinely despite the risks involved. In the decades that followed, the mill fell silent and gradually deteriorated, until it was eventually restored to its current condition.

When is the best time to visit?

Given that the route is a forest walk along a stream, spring and autumn tend to be the most pleasant seasons, with mild temperatures and enough water flow to make the most of the waterfall and ravine. In summer, the valley's cool microclimate and the shade of the trees make it a comfortable alternative to more exposed trails in the region. Sturdy footwear is worth bringing, since parts of the path, while easy, run over uneven natural ground.
