Points of interest

The Señorío de Bértiz Natural Park is located in the municipality of Bertizarana 49 kilometres north of Pamplona along the banks of the river Bidasoa. (Access is via the village of Oronoz in the Baztan valley or Oiergi in the Bertizarana valley).

The protected area was once privately owned and belonged to the sitting Lord of Bertiz from the 1600’s until 1898, when it was acquired by Pedro Ciga Mayo who oversaw the planting and reforesting schemes that can be seen today. He donated it to the local community of Navarre in 1949, with the condition that it was “maintained in its current condition and used exclusively for recreational, educational and scientific purposes”.

To the south, in the lower zone of the Bidassoa river and close to the town of Oronoz-Mugaire, are the palace and gardens standing on 3.4 hectares which include an abundant botanical collection, with species represented from all over the world.

The northern area of the Señorío de Bértiz Natural Park is a succession of valleys and mountains covered with native atlantic forest of beech and oak.

There are several forest tracks and footpaths that lead to the top of Mount Aizkolegi where there is a castle house, now abandoned, from which you can enjoy magnificent views of the park.


The tranquility that this Natural Park enjoys allows the observation of some of the common mammals in the area such as wild boar, fox, badger, stone marten, hedgehog, roe deer. Others also present although with less density are otter, polecat, genet and wild cat.
