The burbling of crystalline water, the light filtering among the leaves of the trees, bathing the landscape in a lime green light and the aroma of nature has made this place, listed as a nature reserve since 1987, one of Navarre's most spectacular enclaves
The Source of the Urederra
is located north of Estella-Lizarra. It is the natural outlet of the aquifer lying under the karstic massif of Urbasa. Its first emergence takes place at an altitude of 700 metres, on the southern edge of the plateau, with an impressive 100 metre fall
that, over millions of years, has modelled a rocky amphitheatre of breathtaking beauty.
After this come other waterfalls and abundant turquoise-coloured pools
that are formed as a consequence of the karstic structure, which lets the water repeatedly seep through the cracks in the rocks from the bowels of the earth. The particular hue of these waters probably inspired the name of the river, as "Urederra" means "beautiful water". Apart from the water, there is also a diversity of flora and fauna
occupying this natural space —beech, oak, elm, maple, yew and almond trees, stand out among the more significant plants, while griffon and Egyptian vultures, kites, eagles and ravens represent the animal kingdom.
A low-difficulty trail
, 5.3 kilometres long, accompanies the river up to it's beautiful source. The route, which is clearly marked, begins on the edge of the car park located at the entrance of the town of Baquedano. After taking the main track and crossing a gate, the trail forks. We recommend going up the left branch, which runs nearer the river and returning along the eastern path, which proceeds at a higher elevation.
The place is part of the Urbasa-Andía Nature Reserve
, located in the Amescoa Valley
, a land of bioclimatic transition, flanked by the Urbasa plateau and the precipitous Sierra de Lokiz. Among other attractions, Amescoa offers several nature trails, many megalithic remains and villages that maintain their traditional nature. To top it all off, you can enjoy the excellent local food, based on local products —beans, lamb, ewe's milk junket, Idiazabal cheese and the famous patxaran sloe berry liqueur.
This is followed by a series of waterfalls and numerous turquoise pools that are formed by the Karst process, by which water filters through the cracks in the rocks, rising time and time again from the depths of the earth. The beautiful colour of these waters no doubt served as an inspiration to the person who named this river the Urederra which, in the Basque language means "beautiful water". Apart from the water, particular mention should be made of the diversity of the flora and fauna to be found in the surrounding countryside: beeches, oaks, elms, maples, yews and almond trees, among other plant species, while the area is also the habitat for vultures, Egyptian vultures, kites, harriers and ravens in particular.
An easy-to-walk trail covering a distance of 5.3 kilometres (there and back) runs alongside the river, going upstream to end in the beautiful river source. The route is marked and starts at the car park located at the entrance to the village of Baquedano. Once you're on the forest track and after going through a gate, the trail splits into two. It's best to take the left path, which runs closest to the river, and then return along the eastern path which is higher up.
This beauty spot, which is currently part of the Urbasa-Andía Nature Park, is set in the Améscoa valley, a bioclimatic transition zone, flanked by the plateau of Urbasa and the rugged mountains of Lóquiz. Among other attractions, visitors to Améscoa can enjoy a number of nature trails, visit a wealth of megalithic remains, and discover villages that still maintain a certain flavour of the past. And, for the finishing touch, you can enjoy the excellent regional cuisine, based on local products and produce such as beans, lamb, junket, Idiazabal D.O. cheese and the popular Pacharán, a liqueur made from sloe berries and anise based alcohol.
The total length of the path is 5.3 kilometres (return) and a difference in height of 200 metres.
We recommend good walking boots due to the irregular terrain, which is impermeable when it rains.
The path is not suitable for persons with reduced mobility nor for children's' pushchairs.
