Putzubeltz ur-jauzia

Putzubeltz ur-jauzia is a waterfall tucked into a forested ravine above Arantza, a small village in the Bortziriak (Cinco Villas) district of northern Navarre. The Basque name combines "putzu beltz" (black pool) and "ur-jauzia" (waterfall, literally "water's leap"), a fitting description for a cascade that drops into a dark, deep pool ringed by rock and greenery.

Where is Putzubeltz located?

The waterfall sits inside the so-called Circo de Arantza, a natural basin at the foot of three peaks: Mendaur, Mendieder and Ekaitza. The small Ibarla river runs through this area and creates its most dramatic stretch right here. Arantza itself is roughly 75 km from Pamplona (about an hour's drive) and around 50 km from San Sebastián, which makes the waterfall an easy day-trip destination from either city.

How do you get there?

The walk starts from the centre of Arantza, where a marked footpath leads into the valley. There are two route options:

• Shorter version — around 3 km round trip with a modest 86-metre elevation gain, taking about an hour and a half. It suits families and anyone who simply wants to reach the waterfall itself.
• Longer loop — about 8.5 km, rated moderate, with close to 400 metres of elevation gain, taking roughly two hours and forty-five minutes. This route pushes further into the Circo de Arantza, with views toward Mendaur, Mendieder and Ekaitza.

Both paths follow the course of the Ibarla through dense, damp woodland typical of this part of Navarre.

What will you see on site?

The waterfall itself is not particularly tall, but its setting makes the visit worthwhile: a mossy, fern-covered rock alcove where the water drops straight into a dark, deep pool — the "black pool" that gives the place its name. Flow is much stronger during the spring melt and after heavy rain, making the cascade far more dramatic than in the drier summer months.

Putzubeltz also carries a local legend: according to Basque folklore, lamiak — mythical women with webbed feet — used to bathe in its waters and comb their long hair with golden combs to keep the place pure. The story is still mentioned in trail descriptions and adds a folkloric layer to the hike.

When is the best time to visit?

Spring and autumn are the best seasons, when the Ibarla carries more water and the forest shows off vivid colour — fresh green in spring, autumn tones after the rainy season. In summer the trail tends to get busier while the waterfall itself runs lower and less impressive. Sturdy footwear is worth packing, since the path through the damp forest can turn muddy and rocky in places.

Frequently asked questions

How long does the hike to Putzubeltz take? The short route takes about an hour and a half round trip; the longer loop through the Circo de Arantza takes close to three hours.

Is the trail suitable for children? The shorter path leading directly to the waterfall is easy and works well for families with kids. The longer loop calls for a decent level of fitness.

How far is Arantza from Pamplona? About 75 km, roughly an hour's drive by car.

Is it worth visiting in summer? You can, but water levels tend to be lower than in spring or autumn, so the waterfall is less impressive.
