Nacedero del Urederra

Recommended if you are driving Navarra. Go out of season, and skip it if you want a viewpoint from a car park.
One of the strangest, clearest rivers in northern Spain, and you have to walk to it.

The Urederra is not a river you drive to. It emerges from the limestone of the Sierra de Urbasa as a series of springs, and the water is so saturated with dissolved rock that it takes on an unreal blue-green colour in the pools. A path follows it upstream from the village of Baquedano through beech woods, and the whole thing takes a couple of hours there and back. In high summer the numbers are capped and the car park fills; outside July and August it is quiet, and better for it. Wear shoes with grip: the path is wet and stony underfoot.
How it got here
The geology of the Sierra de Urbasa dictated the human occupation of these valleys for centuries. Paleolithic and Neolithic artifacts in the surrounding caves confirm that nomadic groups utilized the mountain pastures and water sources long before permanent settlements formed in the foothills. During the Middle Ages, the Kingdom of Navarra managed these woodlands as commons for livestock grazing and timber extraction. The survival of traditional transhumance routes across the high plateau prevented industrial enclosure, keeping the valley floor relatively unchanged. Today, the village of Baquedano serves as the primary gateway to the karst drainage system that defines the local landscape.
Where it sits
Water carves the limestone of the Sierra de Urbasa, forcing the river through a narrow, forested ravine before it spills into the pools of the Nacedero. Beech and oak trees shade the path from the village, keeping the temperature low even during the height of the Iberian summer. Heavy rainfall in the autumn and spring feeds the springs, swelling the volume of the river considerably. The trails turn to mud during the wetter months, requiring sturdy boots for the uneven rock beds. The quiet of the winter months attracts few visitors to the woods.
What to eat and drink
Navarra produces some of the finest vegetables in the peninsula, particularly the white asparagus from the Ebro valley and piquillo peppers, which are roasted over embers. A hearty meal here often centers on cordero de Navarra, local lamb roasted with salt and rosemary. The region also produces cuajada, a traditional sheep milk curd served in wooden vessels, often with a drizzle of honey. Patxaran, a liqueur made by macerating sloe berries in anise, concludes almost every local meal, providing a sharp and herbal finish to the heavy flavors of the mountain cuisine.
Navarra: the whole region
A region of contrasts packed into a small space: Pyrenean valleys and Atlantic beech forest in the north, Pamplona in the middle, and the Bardenas Reales — a desert of eroded badlands — in the south-east, which nobody expects at this…
