Why the Nacedero del Urederra will win you over
Turquoise water in a karst valley
The river Urederra is born in the Nacedero del Urederra, in the Sierra de Urbasa, in Navarra, the natural outlet of the Urbasa karst massif aquifer. Its name means "beautiful water" in Basque.
The turquoise colour comes from the karst terrain: the limestone rock dissolved by the water creates caves, cracks and springs. The water, loaded with calcium carbonate and microalgae, scatters light and produces those tones. The tufa, a light stone created by lime deposits, shapes ledges, horsetails and "giant's kettles".
In spring and autumn, the oblique light and the generous flow enhance the spectacle; in summer, the flow decreases and the forest provides cool shade. A cold and sweet murmur accompanies every step as if the forest were breathing.
It is a very sensitive and valuable reserve for the biodiversity of the Urbasa-Andía Natural Park, with woodland birds, amphibians and a humid flora of an Atlantic character. The communities of Améscoa Baja take care of the access points and organise visits with a quota system to protect the place; visiting it with respect contributes to its conservation.

Essential information: location, opening times and capacity
The Nacedero del Urederra is in Navarra, in the municipality of Améscoa Baja, and you enter from the town of Baquedano, within the Urbasa-Andía Natural Park. It is located north of Estella-Lizarra, about 20–25 km away, between Pamplona and Vitoria-Gasteiz, on the southern slope of the Urbasa massif.
By car, Estella-Lizarra is 30–35 minutes away; Vitoria-Gasteiz, 60–70 minutes via the A-1/NA-718, with mountain passes and curves; and Pamplona/Iruña, 60–75 minutes via the A-12 to Estella and then the NA-718. Calculate between 2 and 3.5 hours for your visit, depending on your stops and your pace.
The terrain is a dirt path with occasional boardwalks, areas with roots, mud and small ramps. It is not wheelchair accessible, and with strollers, you can only use off-road models and only up to the first viewpoints, with caution.
The best time is spring, with high flow and intense greens, and autumn, with the colours of the beech forest. In summer there are more people and less flow, and in winter the days are short and there may be frosts.
The site operates with seasonal opening times: access opens in the mid-morning and closes in the afternoon, with wider time slots in spring-summer and shorter ones in autumn-winter. In case of heavy rain or risk of strong wind or snow, access may be restricted for safety and conservation reasons, so check the updated information from the Urbasa-Andía Natural Park or from Turismo de Navarra.
The Nacedero has a daily quota to limit impact: it is essential to book in advance on the official website, and the quota sells out quickly on weekends and holidays in spring and autumn and in summer. During the week there is usually more availability.
Access is free, but you must pay the Baquedano parking fee: cars 5€, motorcycles 2€, motorhomes 10€, minibuses 25€ and large buses 50€. It is mandatory to park in the reception area car park and parking in the streets of the village without authorisation is prohibited. The entrance barrier opens automatically with a QR code, on your mobile or printed.
Access to the final section of the route is prohibited for conservation reasons and flying drones is prohibited to avoid disturbing the wildlife. There are no drinking fountains on the route, so bring enough water.
To sleep, Estella-Lizarra has services and restaurants, and Zudaire or Eulate, in the valleys of Améscoa, and the rural houses around Baquedano are good bases. In high season it is advisable to book in advance, and sleeping nearby allows you to enter early, with soft light and fewer people.
Before setting off, check opening times, available capacity and possible temporary closures in official sources (Gobierno de Navarra, Parque Natural de Urbasa-Andía, Ayuntamiento de Améscoa Baja).
How to get to and park in Baquedano
To get to the Nacedero del Urederra, take the NA-718 and, from there, the NA-7187 to the parking lot at km 13,8. Baquedano is the starting point for this mountain route in the Améscoa Baja valley.
From Estella-Lizarra, head out via the NA-718 towards Urbasa-Andía/Olazti. After passing Zudaire, follow the signs towards Baquedano and the Nacedero to the marked parking lot at the edge of the forest: 30–35 min with final bends.
From Pamplona/Iruña, take the A-12 to Estella-Lizarra and continue via the NA-718.
From Vitoria-Gasteiz, go via the A-1 to Alsasua/Olazti and join the NA-718 towards Urbasa. Cross the Urbasa pass, where bends and fog are possible, descend to Améscoa Baja and detour to Baquedano following the signage: 60–70 min.
The NA-718 is in good condition, but it is a mountain road in its high sections. Reduce your speed on the bends and watch out for cyclists and potential wildlife at sunrise and sunset. In winter, there may be ice and fog banks, so check the report before setting off.
The parking lot requires payment: cars usually pay a fixed daily rate, with different rates for motorcycles, minibuses, and buses. Access to the Nacedero is free. Confirm amounts and payment methods upon arrival.
The parking lot is spacious, but it fills up on weekends and bank holidays. If it is full, do not park in the verges or in non-designated areas. Return early or late, leave your car in towns within the valley that have designated areas and hire a local taxi for the final stretch, or visit on a weekday.
Access requires prior booking due to the limited capacity of 500 people per day. During peak season, there is control by staff who verify the permit and, if applicable, the reserved registration number. Access to the final section of the path is prohibited: the source of the river is not open to visitors.
Without a car, keep in mind that there is no nearby train station; the most useful ones are in Pamplona or Vitoria. There are regional lines to Estella-Lizarra from Pamplona and occasional connections towards the Améscoa valley (Zudaire/Eulate), from Monday to Saturday except Sundays and holidays, with limited schedules and changes. Check the current frequencies.
During the season, there are operators that organise outings with transport included from nearby hubs. If you want to forget about the car, it is a convenient option.
Arrive early and avoid the peak crowds, such as 11:30–15:30 on weekends. On hot days or after rain, the parking lot may operate on demand depending on the safety of the path. Bring some cash in case card machines fail and respect the local signage.
Permits and bookings: steps, costs and checks
Nacedero del Urederra limits access to 500 people per day. The permit exists to protect a fragile ecosystem: it controls capacity and schedules for conservation and safety.
The access permit is free; parking in Baquedano must be paid for separately. Bookings are managed through the official platform of the Nacedero, the Town Hall and the Natural Park, and during the season there may be information points in Baquedano for any issues.
Weekends, holidays and long weekends sell out days or weeks in advance during high season; during the week there is usually more availability. Tickets are organised by time slots or shifts, so arrive during your assigned window.
To book online, choose the available date and time slot and indicate the number of people, adults and minors. If you are using the parking, add the vehicle registration number. Then enter your email and contact details, accept the conditions, confirm and save the receipt with the code or QR code that arrives by email.
Carry the permit on your mobile phone on the day of your visit and, if you can, also a printed copy in case the signal fails. Arrive with a 15–30 minute margin for access control and parking. If the email does not arrive, check your spam and promotions folder; if you change cars, update the registration number via the link in your confirmation or contact the information point.
Organised groups, especially those with a bus, must arrange the booking further in advance and confirm the specific access conditions. Bring your ID or identification document: staff may request verification.
The cancellation policy may vary by season; in general, you can cancel or modify your booking via the confirmation link with enough notice to release the spot. If there is a closure due to weather or safety reasons, local authorities will inform via their channels: check for updates the day before and on the morning itself.
The permit does not grant the right to swim or to leave the paths, and access to the final section of the trail and to the source of the river is prohibited to guarantee its conservation. If you arrive without a booking on control days, you will likely be unable to enter.
The 6 km route (round trip) starts in the village of Baquedano and lasts approximately 2 hours.
Rules and responsible conduct for the booking
A single step off the path can break tufa that took decades to form. The rules of the Nacedero del Urederra protect the forest, the water and your own safety, and products that reach the river alter its turquoise hue.
Respect ropes, handrails and walkways: do not cross onto the tufa islands or skirt around the pools. Bathing and splashing are not permitted in protected areas and can lead to a fine. The water is cold and the pools are deep, so a rescue puts emergency teams at risk.
Fire and cigarette butts are strictly prohibited due to the risk of fire. Apply "zero waste": everything that goes up comes down with you. Do not collect plants or mushrooms, do not disturb the animals and leave logs and stones where they are. Keep your volume low and avoid speakers and music. Dogs must always be on a lead; pick up their droppings and prevent them from entering the water.
The Nacedero is a karst system with calcareous tufa, bryophytes and amphibians sensitive to turbidity and chemicals; disorderly movement erodes banks and compacts soil. Failing to comply with environmental rules in a Natural Park leads to administrative sanctions in accordance with regional regulations, with fines that can be high.
Plan your visit by choosing off-peak hours and checking the weather, walk along the path and yield the way in narrow sections. Do not feed the wildlife: keep your picnics packed and eat far from the pools. Use the toilets at the car park before entering and group your photo stops at the marked viewpoints. If you are in a group, walk in a line and converse in a low voice.
Report inappropriate behaviour or damage to the access control staff or to the Améscoa Baja Town Hall. If you detect litter, pick it up if it is safe to do so and, if not, notify the park services. Remember that it is necessary to book in advance.
What to see and recommended 6 km itinerary
Turquoise waterfalls and pools: where and when to see them
The Urederra path links thin veils, slides and jumps with still pools. The colour changes with the flow: with generous water, in spring, after moderate rains and in autumn, the turquoises intensify; in summer the water is low, clear and calmer.
The first viewpoints serve to familiarise you with the colour and to take close-up shots without leaving the path. In the middle sections, the river meanders in emerald pools and the wooden handrails give you safe angles. At the final viewpoint of the nacedero, the water springs out at the foot of the cliff, surrounded by limestone walls: respect the distance and the boundaries.
Light is as important as the flow. Avoid the sunny midday due to reflections and harsh contrasts; look for the early hours (9:00–11:00) or the last light (16:00–18:00 depending on the season). Cloudy days diffuse the light and saturate greens and turquoises.
If you carry a camera, a polariser reduces reflections. With a tripod, exposure times of 0.3–1 s give a smooth silk effect to the water, always from designated areas.
Viewpoints, geology and the landscape that sustains them
Official viewpoints have panels and railings, and from them you can see the surroundings without eroding them. There, you will find tuff ledges, a porous rock formed by lime deposits, and "giant's kettles", circular pools carved by water swirling with sand.
Active tuffs have fragile edges: do not step on them or sit on them. Stay behind the railings, do not invade the ledges and avoid approaching cliffs or slippery slopes.
The limestone cliff is the wall where the river is born, with seepages that exude mineralised water. The incised meanders form stepped pools over bedrock.
Balcón de Pilatos is a complementary visit to Nacedero del Urederra. You park next to the viewpoint in Zudaire, on the NA-718 road, and the route uses sections of the Camino Natural Senda del Pastoreo and the SL-NA 296 (Sendero del Circo kárstico de Ubaba). The route is demanding due to distance and elevation gain and requires good physical fitness; in return, you have views over the Améscoa valley and the rocky wall of the source of the Urederra river, with frequent sightings of griffon vultures and other raptors.
Balcón de Ubaba is walked from the Ubaba car park: a couple of kilometres there and back, flat and without elevation changes, returning via the same path.
To conserve the environment, it is enough to look, photograph and take notes without stepping off the path.
Recommended 6 km itinerary: times and key points
Six kilometres and 124 m of gentle cumulative elevation gain separate the Baquedano car park from the Urederra waterfalls. The route starts there and can be done with family, with a camera or at a hiker's pace.
The car park is regulated and you must book your entry online on the official website. The best time is spring, because of the flow, or autumn, because of the colours of the European beech forest. The spring is the natural outlet of the aquifer formed in the Urbasa karst massif, and the forest brings together European beech, oak, elm, maple and European yew, with Egyptian vultures, black kites and sparrowhawks.
The first section goes from the car park to the first pools: a dirt track that goes into the European beech forest, with a signposted diversion to the river and a first viewpoint with intensely coloured pools. Then the waterfalls and the walkways arrive, via a narrow path with railings, some short ramps, roots and viewpoints with railings among the tree trunks.
The third section goes up to the spring viewpoint, at the end of the valley: a short and comfortable climb, with a final section of strict boundaries and a frontal view of the source. The return goes via the opposite bank, through a wider forest path with fewer approaches to the water, between clearings in the European beech forest and mushrooms in autumn (without collecting).
Times depend on your pace. Families do well at 20–25 min/km, with breaks at the viewpoints. Photographers need 15–20 min per viewpoint, with a tripod and filters, and it is advisable to enter early. Hikers advance at 12–15 min/km.
Save water for the return journey, which has fewer areas next to the river. With mud, poles help on the short ramps. And do not improvise shortcuts: the ropes are not suggestions, they are limits.
Variants and alternatives: family route and hiking extension
With children or with off-road strollers, the most comfortable option is to go and return to the first viewpoints of the turquoise pools, always via the same path. The family variant is less demanding, allows more time at spacious viewpoints, and makes managing schedules easier. In exchange, you do not reach the final spring or some of the connected jumps.
The hiking extension adds loops via parallel forest paths marked on the return side. You gain silence, fewer people, and more beech forest, but you lose contact with the pools and the terrain is more slippery after rain.
Outside of this itinerary is the Balcón de Ubaba or Pilatos, in the upper part of the massif, with an independent route and access. It offers an aerial panorama of the valley; it is not advisable to combine it on the same morning if you want light and tranquillity at the river.
All these variants require the same access permit when it is in effect. If you plan long photo stops, choose an early time slot.
Tips, frequently asked questions and next steps
Practical tips: equipment, safety, best times and photography
Going light and well-prepared changes the visit: the cool shade of the beech forest invites you to extend your stop. Wear boots or hiking trainers with good soles, as there is frequent mud in shaded areas. Calculate 1–1.5 L of water per person and snacks that do not produce waste.
Pack light layers and a waterproof jacket in your backpack even if the forecast is stable; in autumn-winter, add thin gloves. A cap, sunglasses, and sunscreen complete the kit, and apply the cream far from the pools. A pair of poles, a mini first-aid kit, and a headlamp will serve you if you run out of daylight.
Check the weather and the report for the NA-718, the Estella-Olazagutía road. After heavy rain, the flow increases and the path becomes slippery: assess the situation and avoid approaching the banks. At the railings, always keep children by the hand. Mobile coverage is irregular, so download offline maps before setting off.
On weekends, book the permit and the Baquedano car park early to avoid changes in plans, and bring cash in case the parking card reader fails. Spring and autumn are the safe bets for flow and colours. In summer, enter first thing in the morning or late in the afternoon to avoid heat and crowds.
Cloudy days soften reflections; with sun, look for side light in the morning or afternoon. Use a polariser to tame reflections and ND filters if you want a silk effect. Use a tripod only in areas where you do not obstruct the path: if there are people, give way. Do not move stones or clean the banks, and avoid using flash with fauna, including birds and amphibians.
Plan the route via Estella or Vitoria depending on your origin. On the NA-718, be patient on the curves and pay attention to cyclists. Arrive with a margin for your time slot, park, and enter without rushing.
Do I need a permit?
Yes. Capacity is limited to 500 people per day and requires prior reservation. Confirm the availability of Urederra reservations before setting off.
How much does it cost?
Entry to the reserve is free. Parking in Baquedano is paid per vehicle: 5 € for a car, 2 € for a motorcycle, 10 € for a caravan, 25 € for a minibus, and 50 € for a bus.
Can you swim?
No. Swimming is prohibited for conservation and safety reasons, with possible sanctions and real environmental damage.
Can you reach the spring?
No. Access to the final section of the path is prohibited and the river spring is not visitable.
What is the parking like in Baquedano?
It is the official access point, with control during the season. It fills up during peak hours, so book and arrive early.
Is there mobile signal?
It is irregular: it works better in the car park and in the open stretches, and inside the beech forest there may be none. Carry offline maps and agree on meeting points.
Is it suitable for children?
Yes, with supervision. The 6 km Urederra route has railings at key points, but there are roots, mud and proximity to water. For the little ones, shorten the route to the first viewpoints.
Can I bring a dog?
Yes, always on a lead. Pick up excrement and keep your distance from the water and the wildlife. During hot hours, prevent them from suffering due to temperature and dehydration.
