The Urdaibai Biosphere Reserve awaits the GR 38

The valleys and mountains that separate the towns of Durango and Gernika are the incomparable setting through which the GR 38 Route of the wine and of the fish runs in this area of Bizkaia. Green pastures, rounded mountains populated with dense forests, together with the well-tended baserris and villages we will pass through, form the magnificent landscape that will surround us along this route.

GR 38 Route of the wine and of the fish Section 6 Durango-Gernika

The stage 6 Durango-Gernika along its 28 km will discover us hidden corners full of mysticism and traditions. Durango and its splendid monumental ensemble refuse to let us leave, showing us part of its character. Iurreta and its church of San Miguel precede the untiring ascent that we have ahead of us in which the Route through the Hermitages will accompany us in part of the journey. It is the hermitages of San Martín, San Juan and Santa Catalina that we will find in this first part of the stage. At all times we are surrounded by the unique Basque mountains dotted with small towns like Mauma.

GR 38 Route of the wine and of the fish Section 6 Durango-Gernika

There are several routes that go through this area of Bizkaia, the GR 229 or the GR 98 Tour of Urdaibai will accompany us in part of our itinerary in which we will have the opportunity to detour to follow some of the variants of the GR 38 that bring us closer to the coastal towns of Lekeitio and Ondarroa. We jump from valley to valley under the attentive gaze of the Balcony of Bizkaia to reach Albiz, to have our first contact with the landscape that surrounds the town of Gernika a little further on. But first it is Mendata that welcomes us before we start the long descent that will definitely bring us closer to historic Gernika, the final point of this stage of the Wine and Fish Route.

The Trick

Given the physically demanding nature of the route, it is not a bad idea to have the possibility of shortening the stage. We have the towns of Albiz and Mendata, which allow us to have them as an alternative if it is necessary to put a stop and go on the stage.

How to get to Durango

Both the AP-8 motorway and the N-634 road pass through Durango, connecting it with Bilbao and San Sebastian, among other towns. We can also reach Durango from Vitoria, passing through Urkiola first, and from Mondragon. Durango also has an Euskotren station and daily services of several bus lines that communicate it with the nearby towns as well as with the capital.

Pet area, hiking with my dog

Intense route that requires a very good physical preparation of our friend, both for the distance and for the unevenness to overcome. The kilometres of asphalt can also make a dent in our friend.

Be aware of the distances between the different points where we can find water, and pay attention to the long stretches in the company of the always dangerous vehicle traffic.

Loose dogs and cattle in some areas of the route will force us not to lower our guard to avoid problems.


Description of the GR 38 Route of the wine and of the fish Section 6 Durango - Gernika

From Durango to Iurreta 1.3 Km

We take as a starting point in Durango (0h 00min), for this stage of the GR, the Ezkurdi Square.

We started this stage of the GR 38 in Durango

From there we will take the itinerary that marks the street that in the previous stage brought us to this square.

We follow the same street

We continue our journey through the streets of Durango as we finished the previous stage, with no signs to help us verify the correct route.

We crossed the river

Fortunately, we will not have to make a detour until we reach the height of the river that bathes the town.

We continue on the right

As soon as you cross it, the itinerary turns sharply to the right, following the street that comes out to that hand.

Again from the right

A little further on this new street forks into two, with the street on the right again being the right choice.

Now down the tunnel

This street takes us to the mouth of a tunnel that will allow us to cross the national road.

We arrived in Iurreta

On the other side, the beautiful square of Iurreta (0h 15min) awaits us, which houses the church of San Miguel and the town hall, among other buildings.

We bordered the church

And it is between these two illustrious buildings that we must continue our journey.

From Iurreta to Mauma 9.6 km

As soon as we pass by them we find the first signposting of the GR 38, which together with the marks of the Route by the Hermitages, will facilitate our work in part.

We continue on the right

We bordered the church of San Miguel to go in search of the road we will have to follow.

Now for the left

When we reach it, we set a course towards the tunnel that will allow us to cross the nearby highway.

We follow the road on the right

As soon as we do so, we will find to our right the beginning of the hard ascent that awaits us.

Watch out for the GR 38 marks

We go up this paved road without abandoning it at the different crossroads we pass through and which give access to the houses that populate this area.

Finish the asphalt

After a while, the paved road reaches its end leaving us at the gates of the small hermitage of San Martín.

We gain height again

A steep trail will be in charge of making us gain height not without effort. This part of the route covered with vegetation forces us to be attentive to find the few marks of the GR 38 that mark the route.

We left behind several crossroads

Fortunately, in most cases the footprint of our trail and the vegetation that almost covers the other options will serve as a reference in case of doubt.

The path continues on the left

After a while the slope seems to give us a break as we reach the vicinity of a new farmhouse that we left on our right.

We gain height again

That truce that the slope had granted us ends earlier than desired, forcing us once again to make a greater effort to move forward.

The trail ends

The wide trail we were following comes to an end when we come across a conditioned path through which we will continue to climb.

We hit the road

Quickly this path leads us to the meeting of the road by which we will continue to gain height.

We pass by the hermitage of San Juan

As if it were an oasis, the hermitage of San Juan tempts us with its welcoming surroundings.

Now for the hermitage of Santa Catalina

After taking a break and recovering our energy we continue the course of the road that leads us to a new intersection. There is the Santa Catalina hermitage that welcomes us, preceding the hard climb that awaits us.

The slope is important

We started to gain height again quickly, following the steep asphalt track that goes up the mountain. A track that we should not abandon in the few crossroads that come out to our encounter.

We continue on a dirt road

At the end of the track a water well awaits us and the beginning of the path that will lead us from now on. The effort involved in travelling this part of the Wine and Fish Route is partly rewarded by the lush forest that surrounds us.

Pay attention to the signs of the Wine and Fish Route

For the moment we are moving forward without too many complications and with the invaluable help of the GR 38 marks at the crossroads we pass.

Another paved road

Marks that we share with those of the GR 229 whose route will accompany us for some time. Once again we see ourselves walking another conditioned path that brings us closer to a small shelter.

The middle path

Here we will say goodbye to the asphalt again as we cross this recreational area.

The slope is not so strong now

The path continues to make us gain height, although not as demanding as in previous sections. Soon the forest is giving way, forced by the logging activity in this area.

The trees disappear

This activity, besides leaving us rocked by the relentless sun, makes us meet the different paths they build to access every corner of the mountain.

We move forward without seeing many brands of the GR 38

Paths that in most cases do not have signs of the GR 38 as they did not exist previously or the tree where it was located has disappeared. Machines and mud have left some areas quite badly damaged.

We begin to descend

We began to lose altitude in the hope of leaving this part of the route behind as soon as possible.

We continue on the right

The descent takes us to a new junction where we will say goodbye to the GR 229 company and enter another wooded area.

Mud can be an annoying traveling companion

Here, as in the previous sections, it is easy to find some mud that complicates our day. Another lonely baserri comes out in our path marking the beginning of another stretch on the asphalt.

We don't leave the road at any time

We began to gain height once again as we followed the course of the paved road that started from the farmhouse.

We arrived at Mauma

In front of us we can already see the first houses of our next target. The small town of Mauma (3h 10min) invites us to make a stop on the way before continuing with the itinerary we are following.

From Mauma to the detour of the GR 38 variants 3 Km

We continue to ascend following the course marked out by the cemented track from Mauma.

The trees are disappearing again

Once again, industrial activity linked to wood is once again on our path. A path that, if it had rained, could become practically impracticable.

The path can become a quagmire.

The deforestation that the area has suffered, linked to the mud that we can find, can make this part of the route quite complicated.

Attention to the GR 38 signals

Luckily the forest is back in the spotlight, at least for the time being. The GR marks are still a great help to us in following the right course.

The path is a pool

Even inside the thick forest we are walking through, if it has rained, the mud and water may force us to look for alternative steps to the path we are following.

We went through several crossroads

There will be quite a few junctions that we will go through, although they are usually well signposted.

The vegetation almost covers everything

Crossroads where the vegetation also does its bit, while we join the route of the GR 98, also known as the Tour of Urdaibai, and with which we will henceforth share the journey on several occasions.

The mud continues to accompany us

The path that once ran through these forests has been reduced to a trail surrounded by vegetation.

We continue towards Gernika

This entertaining area comes to an end when we come across the cement track where we will continue and where we will find the detour of the GR 38 variants (4h 10min) which if followed would take us either to Lekeitio or to Ondarroa passing first through the town of Bolibar.

From the detour of the GR 38 variants to Albiz 4.1 km

We left behind these variants and began to lose height following the course of this conditioned path.

We left the path

Shortly before hitting the road, it is time to say goodbye to the path and enter a battered trail that borders the tree line on our right.

We crossed the road

This trail leads us directly to the encounter with the road that the previous route wanted to lead us to. We will have to cross this road in order to continue with the route on the other side.

We continue to descend

Once again we are surrounded by colossal trees, following the path we took on the road without any further detours.

The landscape is visible for a moment

We began to lose height little by little as we enjoyed the panoramic views of the area.

The slope is remarkable

The slope begins to become much more evident as we head towards the valley we used to see.

Be careful not to get lost

Also in this section of the route we will come across several crossroads where we will have to be careful not to miss the chosen path.

The vegetation will help us in case of doubt

Although in most cases it will be the vegetation itself that will show us the path to follow.

End of the descent

After a steep descent, the path that follows the course of the river to which we have descended awaits us.

We crossed the river

Ahead we have a short section going up the riverbed until we reach the bridge we will cross.

The slope is very demanding

Already on the other side some hard ramps await us that will make us recover part of the height previously lost.

We approach Albiz

After a zigzagging and notable ascent the forest leaves us warning us of the proximity of the next town we will visit.

We crossed the road

Once again we will be forced to cross the road that cuts us of the pass. Albiz (5h 15min) or rather the outskirts of this town, awaits us on the other side of the road.

From Albiz to Mendata 2.9 Km

We continue to ascend

We continue to gain height, now without so much demand, as we tour this area of the town.

We continue to gain height

Shortly after saying goodbye to her and going through a cattle gate, the path we are following forks and must follow the one on the right.

Now for the left path

This path leads us to the interior of another thick forest where it divides in two again, being in this case the path on the left the correct one.

We go through the forest

A beautiful route awaits us, crossing the forest until we leave it shortly after going through another gate for the cattle.

We continue on the right

It is at the edge of the forest where once again our path divides in two, being in this case the one on the right that we have to follow. From here we can already contemplate the figure of our final destination and intuit the itinerary of the next stage.

We descend again

We begin to lose altitude with our eyes set on the next town to which the Wine and Fish Route takes us.

We continue on the right

But we still have a long way to go before we can visit her.

We go out to the road to Mendata

After a stretch of paved road, the road that we crossed to get to Albiz awaits us, a road that we will follow without major problems thanks to the promenade that runs through it.

The road takes us to Mendata

The road is in charge of driving us to Mendata (6h 05min) not without first forcing us to climb a demanding slope.

From Mendata to Gernika 7,1 Km

We leave Mendata

It is this same road that guides us through the town leading us to the beginning of the path we must follow.

We follow the path on the left

A path that follows the itinerary marked by the enormous crosses located there. Crosses that accompany us until the beginning of the descent that will take us to Gernika.

We're starting to lose altitude again

Once again the steep ramps we face make us lose altitude quickly. There will be several crossroads that we leave behind without these should make us doubt the itinerary to follow.

We go out to another asphalt track

The descent seems to come to an end as we come across a new asphalt track on which we will continue.

We say goodbye to the path

But nothing could be further from the truth, since when we reach the end of this track we will turn to our right to resume the descent.

Watch out at the crossroads

An unevenness that gives us a little break again soon after. This area once again has several crossroads where it is quite clear the option to follow.

We gain height again

Not much later we will be forced to climb another slope that at this point of the route becomes harder than it really is.

We continue to approach Guernica

This section is also well marked by the usual presence of mud that hinders our progress. Gernika looks closer and closer, although there are still a few surprises.

The brands are sending us from the right

A wire fence delimits a new fork in the path, here the official itinerary of the guides does not correspond with the marked route since someone has taken a lot of trouble to mark the path on our left with several of the typical GR crossings that indicate that we should not continue along this path, despite it being the one we were supposed to follow.

We descend again

A meticulous work of signaling that concluded there, since there are no more marks that indicate the path to follow, which has to be the path of our right.

There are no other brands of the GR 38

This path quickly descends again, moving away from the nucleus of houses that separated us from the nearby road to Gernika.

Do not deviate

This battered path leads us to the encounter of a small river. A river that we must not cross if we want to get to the road we are heading for.

We came across some brands of a PR

Luckily the path improves in its state of conservation, anticipating our arrival on the road that awaits us.

We ascend following the road

The road along which we will resume the course of the GR 38 not without first facing a demanding steep slope.

Here we would have left if we had followed the old GR 38 route

Already above we will be joined by those who ignored the marks followed the old course of the GR 38.

The bicycle lane serves as a reference to follow

Once we are together we will see ourselves following the course of the bicycle lane that borders the narrow two-way road that guides us.

We are approaching Guernica

There is no other choice but to cross the industrial area that precedes the town of Gernika. Once again, the absence of marks or signs on the GR 38 obliges us to use the common sense that leads us to pass under the town's ring road.

We follow the street parallel to the Euskotren tracks

Without making a detour at the different crossroads that we pass, as soon as we cross the train tracks, we will reach the street that, parallel to the train tracks, will take us into Gernika.

No detours for the moment

For the time being, we must follow this street that runs alongside the train tracks. Shortly before reaching the train station in Gernika, our street forks, separating us from the tracks that accompanied us here.

Now down the street on the left

A little further on on our right we can see the Euskotren station building. After leaving it behind, our route changes direction radically, making us follow the street that emerges on our left.

We continue to the arcades

A large square is waiting for us a few meters ahead and as soon as we reach it, we will see in front of us the street we have to follow. It is a pedestrian street that makes us pass under some arcades to leave us at the gates of the Foru Square of Gernika (7h 50min) where this stage of the Wine and Fish Route ends.


Technical data sheet of the route

ico-distancia-totalDistance. 28Km

As is usually the case, the passage through large towns and cities can vary this figure.

ico-tiempo-totalTime. 7:50h

The state of the ground in some parts of the route can influence the time we need to spend in this stage.

ico-calendarioTime of year

Fog and rainy days are not good travel companions and even less so on this stage of the GR 38. The good weather will allow us to make better use of the landscapes that will surround us along the route.

ico-materialRequired equipment

This is a route of a certain distance and in some areas not very well signposted so it is important to take what is necessary to follow the route without the GR signs and bring enough water and food. The mud that we will surely find in several sections also forces us to be proactive and throw the gaiters to the backpack just in case. Consult our list of material and equipment for hiking. Read more.

ico-dificultadDifficulty. Remarkable


Without a doubt, this is one of the most demanding stages of our journey. The distance and the unevenness to be overcome will put our physical condition to the test, not only the hard ascent areas, but also the descents have their wear and tear. The humidity and heat, both separately and together, will make this stage of the Wine and Fish Route even harder.

Severity of the environment

A lot of caution not only to the crossroads with the roads, but also to the long stretches that we will travel through them. We must also pay attention to the urban sections and not just focus on looking for the marks that tell us where we have to continue. The rest of the itinerary, as it mainly goes along paths and tracks, is not very complicated, except for the problems that muddy areas and steep descents can cause.


As usual, and unless someone deigns to correct it, we will find areas well marked and others of total absence of marks and signs. Besides, we will see again how almost at the end of the tour the marks do not coincide with the tracks and explanations that we will find in most of the guides.
