Hiking in the Izki Natural Park

The Izki Natural Park, in Alava, is a true temple of nature, crisscrossed by countless hiking routes. The woods and villages rival the steep mountains where they grow. These mountains are home to the tranquil Izki River, from which the park takes its name. The house of the park or parketxe is located in the village of Corres-Korres and is the starting point for a good number of the paths that pass through this valuable natural area. Paths that intertwine with each other, such as the Path The Agin or the Path Antoñana, allowing us to draw the route that best suits our tastes.

Path The Agin or the Path Antoñana

The 7.4 km circular route formed by these two Izki paths takes us to say goodbye to Korres and to climb up to the Avellanado Pass. From there we have the not inconsiderable possibility of approaching the summit of Soila, following the imposing rocky ridge that separates us from it. After visiting this summit and enjoying the spectacular landscape it offers, and the vertiginous cave that is hidden in the ridge that we have visited, we return to the pass to begin the entertaining descent that we have ahead of us. A dizzying trail goes along the strip that cuts the mountain cliff. The rope with which it is equipped serves as a handrail and also helps us to master this vertical cliff.

Path The Agin and Path of Antoñana Izki Natural Park

Once in the forest, the descent leads us to visit one of the lords of the forest. Some big linden trees and the majestic yew tree are waiting for us in this part of the route that takes us to the encounter of the Path of Antoñana, by which we will return. A return route that offers us the possibility of extending it by following the detour that links it to the Path of Bujanda. On the other hand, the Antoñana path, before taking us to Korres, allows us to look out over a spectacular viewpoint, from where we can contemplate a large part of the Izki Natural Park before reaching Korres, the end point of this hiking route.

Path The Agin and Path of Antoñana Izki Natural Park

The Trick

From the Korres itself, routes of different levels start, from ideal routes for the family, with children, to routes of considerable demand. In many cases, the paths communicate with each other, either directly or through duly signposted links, which considerably broadens the possibilities. In this case we can join the Path Antoñana with the Path Bujanda and have a circular route of great interest and somewhat less exposed than the one described here.

How to get to Corres

The main access route is the A-132, the road that connects Vitoria-Gasteiz and Lizarra-Estella. In Maeztu we find the road that goes to Corres-Korres. Another possibility is the road that connects Santa Cruz de Campezo and Bernedo, passing through Bujanda. It is on this road that we can turn off to the town of Corres. Once in Corres-Korres, next to the house in the park, there is a car park with spaces for cars where we can park our vehicle and start the route.

Pet area, mountain with my dog

Like all natural parks, Izki has its own specific regulations for pets. As it is a nesting area, you should check first, as there may be some restrictions depending on the time of year.

This is a route that should not cause you any major complications. It is important to bring, as always, some food and water. Be very careful in the area of the ridge, we don't want any trouble.

It is not strange to meet the cattle and other pets along the route. It is advisable to take a look at the end of the route to rule out parasites.

Description of the Path The Agin and Path of Antoñana

From Korres to Soila 2.6 Km

The Izki Natural Park House in Korres (0h 00min) is the starting point for our hiking route.​

We started the route in Korres

Our route begins in the large car park next to the Izki parketxe, taking us up the street that enters from the nearby road.

We left the house in the park behind

Right at the end of the building, the path begins along which we must continue. At the moment we begin to gain height surrounded by thick vegetation, a prelude to what awaits us.

We follow the Path The Agin of the Natural Park of Izki

Vegetation that practically swallows up the road we were climbing. We quickly come across a first crossing, where a post indicates the continuation of the trail we are following.

Vegetation covers the entrance

Luckily, the vegetation that almost prevented us from passing leaves us some margin, allowing us to enjoy a pleasant tour.

The vegetation gives us a break

The trail we follow, in spite of the lush vegetation that surrounds us at times, keeps its footprint. There will be several junctions that we will leave behind as we continue to gain height with each step.

We went through several crossroads

The different paths that we cross and that run through this part of the park do not confuse the direction we should take. After a while, a fence gets in our way, allowing us to cross it without any problem.

Atentos a las marcas del sendero

The path we must follow, although signposted, forces us to be vigilant at the various crossroads we pass through.

The marks are not seen on some junctions.

In some of them the marks of the path are not as visible as in most cases.

The bushes take over the trail again

Once again the vegetation makes our progress difficult, although fortunately the path continues to be visible below it. The slope alternates moments of greater demand with others much more relaxed.

A small clearing in the forest

We also alternate sections where the vegetation gives us a break allowing us to enjoy the landscape around us.

The section with the greatest slope begins

Soon the slope increases, warning us of the proximity of the ridge towards which we are heading. This area forces us to make a greater effort in order to keep gaining height.

The zigzagging trail

As it could not be otherwise, our trail begins to wind along the mountainside looking to soften its slope.

The trail turns again

Little by little we are gaining height by following the paved path that is guiding us in this section of the route. A solitary post warns us of our arrival at the pass where the descent towards Antoñana begins.

We reached the ridge

We leave this descent for later and set a course for Soila by climbing the ridge that separates us from it.

We advance towards the Soila

This area, now unmarked, continues to combine sections where the vegetation almost prevents passage with others that are more open.

Don't lose height

We have to find several trails, in any case it is best not to lose the height gained and stay close to the ridge that we are bordering.

The summit is already near

There will also be several trails that we will leave behind and that will rush down the slope. The summit of Soila (1h 00min) awaits us to give us wonderful views of the Izki Natural Park from the villages in the area, which more than make up for this detour.

From Soila to Korres 4,8 Km

After enjoying this place we will return to the crossroads that we left behind and that marks the beginning of the spectacular descent that we have ahead of us.

We retrace our steps

Once there, we looked at the most aerial section of the entire route. This is a trail that borders the strip that crosses the rocky outcrop that crowns the mountain.

Watch out in this area

To avoid problems, we have a rope that we use to pass through this dizzying passage.

We have to go down this way

The same rope marks the point where we must leave the cliff.

It's not complicated but you have to be careful

This short descent has good grips and the invaluable help of the mentioned rope.

We continue to descend

After saving this first hurdle we continue with the descent following the, sometimes, decomposed trail that we have to walk.

The trail softens

This trail soon softens its slope and begins to border the cliff we had walked on before, leading us back to the top of the Soila.

We passed under some linden trees and a yew tree

This area has no greater complication than the stony trail. In exchange it allows us to visit the lords of the forest, some huge linden trees and the unique yew tree.

This section of the descent is also delicate

After doing so, a new stretch of dizzying descent begins, in which the company of the rope is missed, even more than in the previous stretch.

Things are definitely smoothing out

Once this steep and rough stretch of the descent has been overcome, both the slope and the difficulty are considerably softened. We continue to be guided by the yellow spots that mark our trail

We went out on a path

After a while the trail reaches its end when it meets a path that goes up the mountain. A path that we will continue to descend without complications.

We walk through a beautiful forest

This section of the route allows us to enjoy the freshness of the beech forest we are walking through.

We go out to the Path of Antoñana in the Natural Park of Izki

Almost without realising it, we arrive at the crossroads with the Path of Antoñana (1h 40min). Here we have to decide whether to walk the short kilometre and a half that separates us from this village or to head towards Korres.

The way forward is clear

In this case we will begin a new stretch of ascent that becomes harder than expected at this point of the route. Here we will also be leaving behind the paths that come out in our path.

We leave the link with the Bujanda Path

Paths such as the one that connects our path, the Antoñana path, with the Bujanda Path (1h 55min) and which allows us to return to Korres through it by crossing the gorge it runs through.

We continue to ascend

In our case we continue to climb without abandoning the Path of Antoñana that will take us to Korres. This section of the route also has the freshness of the thick vegetation that covers these mountains, but in this case does not complicate our progress.

We approached the viewpoint

The rocks that characterize Izki can be seen without complexes, giving a special touch to this part of the tour.

We swerved to the lookout point

A route that takes us to the proximity of a magnificent viewpoint (2h 15min) to which without hesitation we turn.

We return to the path of Antoñana

After taking a well-deserved break in this unique corner of Izki, we return to our path to continue towards Korres.

We start the descent

After passing another gate we start the final descent that will take us to this town in Alava. Although we still have a long way to go to reach it.

Watch out at the crossroads

Once again, there will be several trails to follow. Until we reach the end of the path we were following.

We go out to the Korres road

Here, in addition to the signs along the way, logic shows us the way to go. This path gradually brings us closer to our final destination Korres.

We arrived in Korres

The one we got to after going through another fence that cut us off. The route takes us around the village church to leave us in front of the street where we must continue.

We finish the trekking route

This street leads us directly to the Izki Natural Park House in Korres (2h 50min), where we will put an end to this entertaining trekking route.

Technical data sheet of the route

ico-distancia-totalDistance. 7.4Km

If our starting point is the recreational area we will have to add a little more than 2 kilometres to this figure.

ico-tiempo-totalTime. 2:50h

If we decide to approach Antoñana we will have to increase this figure by almost 1h. It will also take longer than that if we return along the Path of Bujanda.

ico-calendarioTime of year

Autumn and spring are the most recommended periods because of the colorful landscape. Since it is mostly in the shade of the woods it passes through, this is an acceptable route in summer. Mud and wet stones are not the most advisable for the descent section.

ico-materialRequired equipment

At least long pants, it is the minimum recommended if we do not want to be exposed to scratches with the bushes and possible parasites, ticks, which are probably waiting for us. We should not miss some water either, as there is no water on the whole route. Food and walking sticks, some gloves to protect our hands in the sections where we will surely have to use them, is not a bad idea either. Consult our list of material and equipment for hiking. Read more.

ico-dificultadDifficulty. Medium


If we follow the route in the described direction, we should not have problems with this section since the difference in level to be overcome is distributed over a longer distance. While if we would do it the other way around it would be concentrated in a shorter space of land. The distance is also not so remarkable as to increase the degree of difficulty in this section.

Severity of the environment

This is where much of the difficulty lies. We will go through quite exposed sections where we have to take extreme precautions, not only because of the possibility of falling into the void, but also because of the many possibilities that we have of stones falling from the areas we have over our heads. We must also pay attention to the parts of the descent that, without being equipped with a rope, are much more complicated or prone to complications than the cliffs.


The vegetation and the different paths and tracks we will come across will be the ones that generate the greatest complications in this section. Although the route is well signposted, we will pass through areas where the marks are not so visible to the naked eye. The detour to the summit of Soila is not signposted and as you walk along it you will come across several paths that descend towards the area of Korres, which of course you do not have to follow.
