BASOAK 4* is a mountain biking route in its purest state. It runs through the northwest of Navarra joining the Urbasa / Andia Range in the first stage, and the Aralar Range in the second. To these 2 natural spaces of first order, are added in the final 2 or 3 stages by the Ultzama Valley (the Navarran Switzerland), and the endless forests full of "flow" trails of the Quinto Real recently reinterpreted by the modern philosophy of MTB tracks developed in the area by the EREMUA Trail and MTB Center.

The PIRINEOS PUNTO BIKE proposal to pedal the route is in broad strokes, a Self Guided Pack which includes the Half Board Accommodations, the Tracks of the route and the Luggage Transport from hotel to hotel.

Stage I of BASOAK MTB is the "Andia / Urbasa Ranges" stage.
After the long section of plain that can be guessed in the profile, which corresponds mainly to the River walk of the Arga between Pamplona and Ibero, the route continues for a few kilometers to the Arakil Basin and then tackles a hard ascent to the Andia Range.
It is not easy to make the decision of the route to choose, option 1, which, crossing the Lizarraga mountain pass, enters from the Andia to the Urbasa Range -a division more administrative than geographical- and ends with a "demanding" descent to Etxarri Aranaz, or option 2, which ascends the 1.495 meters of Beriain summit and then descends in a more relaxed way through the town of Unanua. We will have to decide in Portillo de Bizkarluz, at almost 1.200 meters of altitude, and sometimes the weather will be the one that makes us decide from one option to the other.
Neither of them is going to disappoint us, the environment of the Andia / Urbasa Natural Park in which we move, magnifies everything.

Cuenca de Pamplona desde Alto de Goni

After a long section of plain, we leave the Pamplona Basin behind with the ascent to Alto de Goñi, a tough climb of those that are not forgotten.

La mole del Pico Beriain Ascenso al Pico Beriain

If we choose option 2 of the stage, we will ascend to Beriain Pic which at 1.495 meters of altitude is one of the highest and most emblematic cyclable mountains in Navarra.
In the photo below, the mountain fills the horizon behind the cyclists. In this case, a peak that is not forgotten.

Stage A: Arbizu - Lekunberri - Distance: 50 km   Unevenness: 1.545 m


Stage A of BASOAK MTB is the "Aralar Range" stage.
After a first foray into the Altzania Range in which we will cross the impressive path of the Millennial Oaks and a succession of remains of various dolmens, the track of the route enters the Aralar Range. Here there is a clear difference between a 1st part ascending on the Gipuzkoa slope and a 2nd part in the Navarre area where, after going flat for several kilometers through the top of the mountain range, we will proceed to descend to the valley at Lekunberri.
With an ancient pastoral tradition, the Aralar range is currently a Nature Reserve which continues to maintain this tradition despite being in the vicinity of some of the most industrialized areas of the Basque Country.

Descent towards Lekunberri. If the snow paints the summits of the Malloak of Aralar, the cycling season in BASOAK MTB ends.


Stage B: Lekunberri - Zubiri - Distance: 61 km   Unevenness: 1.635 m


For almost 40 kilometers the profile of this 3rd stage is made up of an uninterrupted succession of meadows and forests regularly interspersed with the typical villages of the Ultzama Valley.
Without great slopes but with constant ups / downs we cross a territory that is "friendly" but in which the isolation that little by little is spreading throughout all the peninsular rural territories begins to be noticed.
If we relax too much we will find ourselves face to face with the last section of the day. A constant "wall" with more than 700 meters of unevenness completely alters the profile of the stage and requires us to stand firm. After a last effort, surely setting foot on the ground, we reached the top of Leateko Gaina summit. It is the time of put our helmet on tightly to drop down the 600 meters of the "Magnun" route - from the new EREMUA Trail / BTT Center - to the reservoir of Eugi and by road to Zubiri.
Lovers of the most enduring descents may choose, if they wish, to descend other more demanding routes such as Anaconda Bong or King Goitean. No matter where you get off, it will be difficult not to arrive at the hotel with a smile on your face.


Stage B begins and the Aralar Ranges becomes an horizon.


Already in the first kilometers the forest -BASOAK- takes center stage.


Etxaleku, "type" town in the Ultzama Valley.

Stage F: Zubiri - Pamplona - Distance: 62 km   Unevenness: 1.485 m


La etapa F de BASOAK es la que devuelve a los ciclistas que realizan la ruta, desde los Bosques del norte de Navarra a su capital en Pamplona.
La etapa esta claramente diferenciada en 2 mitades con diferentes ambientes. En la primera se mantiene la "tensión escénica" de los interminables bosques de hayedo que caracterizan BASOAK. La ruta se interna por los rincones de la Selva de Anue, un entorno más conocido como los Montes de Belate y tras un descenso cuidado por los bikers locales por el antiguo sendero de las Minas de Lantz, desciende primero a esta localidad y después a la de Aritzu, ya en el fondo del valle.
En la 2ª mitad de la etapa, el paisaje cambia bruscamente. Entramos en el Valle de La Ultzama, atravesando inicialmente una sucesión de prados y pueblos de carácter apacible y domesticado. Sorprendentemente el ambiente se torna más agreste según abandonamos el valle y nos acercamos a la ciudad. En los últimos kilómetros encadenamos diferentes sendas de las utilizadas por los ciclistas locales en sus salidas rutinarias desde Pamplona.

Variante Valle Esteribar: La etapa F dispone de una opción de ruta (F9) orientada prácticamente en su totalidad hacia el sur. Esta variante aprovecha las nuevas sendas recuperadas por el Centro de BTT y Trail EREMUA en la zona sur del Valle de Esteribar y se dirige hacia Pamplona encadenando una serie de ascensos y descensos que podemos combinar de diferentes maneras para reducir o alargar la dureza de un recorrido que en su versión completa alcanza los 43 kilómetros con un desnivel acumulado de 1.470 metros.
Es esta una opción muy utilizada cuando los ciclistas están finalizando BASOAK MTB y desean realizar el viaje de vuelta a sus lugares de origen el mismo día en que realizan la etapa.

Stage H: Zubiri - Zubiri - Distance: 55 km   Unevenness: 2.015 m


La etapa H de BASOAK MTB es una etapa circular por la sección más occidental de los bosques del Quinto Real.
Diseñada para ofrecer la posibilidad de añadir una etapa a las opciones de BASOAK MTB que hacen noche en el Valle de Esteribar, habitualmente en Zubiri, esta etapa viene a ser el Tour del Adi, una de las montañas más emblemáticas de Navarra, y con un "Rincón" -el de su cara norte- que para nosotros se convierte en uno de los pasos "obligados" de la ruta.

La etapa "respira" el carácter de las nuevas sendas del Centro de BTT EREMUA y las combina con el ambiente de los territorios fronterizos pirenaicos de los pastizales de Sorogain y el desconocido "Quinto Norte" una franja de territorio con peculiaridades históricas tan sorprendentes en las que pese a ser de titularidad española, sus habitantes son franceses. Pastores, carboneros, contrabandistas, militares... los pasos del pasado marcan las sendas del presente.

  • Best time to go: > The route can be done once the snow disappears in the highest mountains of the route. From there, we dare not say that one era is better than another. It really depends on the specific weather of the days we choose.
       Do not underestimate the weather, not even in the middle of summer. The conditions -especially in the Pyrenees- can be identical to those of the Central Pyrenees. To summarize... our advice is: bring even the long culotte and if it doesn´t come out from the suitcase, all the better.
       In summer it is necessary to be aware of the possibility of storms -frequent in the afternoons-.
  • Type of tracks: In general, trails and tracks with more physical than technical demand, both uphill and downhill.
       For the technically demanding sections - that sometimes there are - we offer alternative tracks, although the simplest way not to distort the route is to get off the bike.
  • Ideal bike: Any mountain bike.
  • Orientation: The route must be followed with a GPS device or with the mobile phone App that you are used to using for the same purpose.
       It is not advisable to try to learn how to use an App on the fly.
       We do not provide Apps or GPS user manuals. It is up to the users to have this knowledge.
       There is no on-site signage.
  • Ciclability: Depending on the technical skills and the strengths of each one, the route is 98% cyclable.
  • Philosophy: The route is designed so that the stages can be completed and we still have a large part of the day to enjoy the place where we are.
  • Provisioning: Although sometimes we find refreshment points, depending on the time of the year we can find that some establishments are closed. In the services waypoint file that we deliver at the beginning of the route the information of each stage is given.
