🍂 Suspiro Route (3 km – easy level)

Its name says it all: it is a relaxing route, designed for a calm walk among beech and chestnut forests. The route is circular and takes just about an hour, making it a favorite option for families or for those looking for a walk without great demands. During autumn, the carpet of leaves turns this trail into a visual spectacle.

🌄 Plazazelai Viewpoint Route (5 km – medium level)

This route offers one of the best viewpoints in the park. After a moderate ascent, you reach the Plazazelai viewpoint, from which you can see much of the Baztan Valley and the surrounding mountains. The walk is perfect for those looking for something intermediate: neither too short nor too demanding.

🏰 Aizkolegi Route (11 km – medium/high level)

The most famous route in the park. This route leads to Aizkolegi Palace, a modernist building from the early 20th century that is now in ruins. Along the way you cross lush forests and, upon reaching the summit, enjoy spectacular views of all of Baztan and part of the Basque coast. It is a demanding route, taking about 4–5 hours, but absolutely recommended.

⛰️ Xorilepo Route (10 km – high level)

Ideal for experienced hikers. It is a more demanding route that combines elevation changes, forest passages, and open stretches with panoramic views. The route is not as popular as the Aizkolegi one, but for lovers of wild nature it is a true gem.

In short, the Bertiz routes let you choose according to your physical condition and the time you have available. All of them are well signposted, and at the visitor center you can ask for an updated map with times and elevation changes.

🌺 The Botanical Garden: the jewel of Señorío de Bertiz

If there is one place that captivates all visitors, it is the historic garden. Created at the beginning of the 20th century, it features species brought from the five continents. Walking through this space is like traveling the world without leaving Navarre.

📸 A paradise for photography

The garden changes with each season: in spring the camellias and magnolias fill the air with color; in summer the coolness of the bamboos creates natural passages; in autumn, red and gold dominate the landscape; and in winter, the mist adds a magical and mysterious touch.

🧑‍🏫 Educational value

Beyond its beauty, the garden is an ideal educational resource. Schools, institutes, and nature groups visit it to learn about botany, ecology, and conservation. It is an example of how nature can be an outdoor classroom.
