It's not Txindoki, but it's also very fun to climb. I recommend descending via the side area where I went.

No wonder they call it "the Basque Matterhorn". Pointy but beautiful. Worth it. And not exposed at all.

A good summit, easy to climb. I couldn't enjoy the views because the sky was overcast, and rain and a strong storm arrived.

The region around Zaldibia, serving as a gateway to the Aralar Natural Park, features several notable peaks. Txindoki (Larrunarri), often called the "Basque Matterhorn," is an iconic summit known for its striking pyramidal shape and panoramic views. Another significant peak is Auza Gaztelu, which offers excellent vistas and historical importance with its medieval castle ruins. You can also explore Gamboa Summit, considered easy to climb, and Sarastarri Summit, known for its surrounding cavities and caves.
From peaks like Txindoki, you can enjoy spectacular panoramic views of the surrounding mountains, Gipuzkoa, and the Aralar Natural Park on a clear day. Auza Gaztelu, despite being lower, offers magnificent views of the Aralar mountains, including a unique perspective of Txindoki itself, and on clear days, you might even see the Aizkorri mountain range and Anboto. Sarastarri Summit and Errenaga Summit also provide stupendous views of the natural park.
While some peaks are challenging, areas like Lizarrusti Pass offer family-friendly amenities. Lizarrusti has a large parking area, a fountain, a children's playground, picnic tables, and information panels about Aralar Natural Park. It serves as a starting point for many excursions into the park, some of which are suitable for families. The routes to Auza Gaztelu, starting from Zaldibia and Larraitz through beautiful beech forests, are also considered pleasant walks.
The difficulty varies. Txindoki is considered a challenging ascent, especially towards the summit, though the main route from Larraitz is well-marked. Gamboa Summit, on the other hand, is described as easy to climb. Other peaks like Sarastarri Summit and Errenaga Summit are generally intermediate. Routes to Auza Gaztelu involve a considerable elevation gain from Zaldibia (730m), making for a rewarding hike.
Txindoki holds significant mythological importance, believed to be one of the dwellings of Mari, the most important goddess in Basque mythology. Auza Gaztelu is historically important, with ruins of a medieval castle on its summit that served as a Navarrese border stronghold in the 13th and 14th centuries. The Errenaga Summit was historically a border point between Gipuzkoa and Navarra, where a customs office once controlled the passage of goods.
