Lagunas de Montañana

Lagunas de Montañana is a cluster of lagoons formed in former gravel pits along the Ebro River, right next to the small village of Montañana, part of the municipality of Miranda de Ebro (Burgos province, Castile and León).

Where is it and how do you get there?

Montañana sits about 7 km north of downtown Miranda de Ebro, on the BU-735 road between the villages of Guinicio and Suzana. The settlement stretches along the bank of the Ebro River — the province of Álava begins right on the opposite shore. From Miranda de Ebro it's a short drive of a few minutes, and the route is also walkable or bikeable along local paths that follow the riverbank.

How did the lagoons form?

The lagoons, known locally as Lagunas de los Yelsos, formed in a meander of the Ebro on the site of old gravel quarries. Once extraction stopped, the pits gradually filled with water and became a network of calm, shallow lakes. It's a landscape typical of the Ebro valley: a post-industrial site that, over time, turned into a valuable wetland.

What will you find there?

Despite visible traces of past gravel extraction, the surrounding area has kept real ecological value. Patches of melojo oak woodland survive among the farmland, and lush riverside vegetation lines the banks of the Ebro. The lagoons and the adjoining river stretch make for good waterbird watching — the calm surface draws a good variety of species, which birdwatchers will appreciate. In the village itself, look out for the parish church of San Andrés, whose structure blends elements from the 13th to the 18th century, and a striking, centuries-old ash tree that serves as a local landmark.

What trails run through the area?

Montañana lies along the long-distance trail "Agua y Roca: Del Ebro a los Obarenes," roughly 60 km long, linking the Obarenes mountains with the Ebro valley between Pancorbo and Miranda de Ebro. The route also passes through neighboring Suzana and other small villages in the Miranda de Ebro district. The stretch along the right bank of the Ebro opens up wide views over the river valley and chances to spot local flora and fauna, from waterbirds to native riverside plants. It works well both for a short walk around the lagoons and for hikers tackling a longer section of the trail.

When should you visit?

Spring and autumn offer the best conditions for visiting and birdwatching, with mild temperatures and stable water levels in the lagoons. Summers in the Ebro valley can get hot, though the shade of riverside trees softens the heat along the walking routes. Winter is quieter, though several waterbird species stay in the area year-round.
