Aralar Natural Park

The magic of vastness

Quite a symbol

Limestone mountains, rivers and natural springs, diverse vegetation and fauna, myths, legends… Aralar has been the main icon of mountain and nature in Euskadi since ancient times.

Geological wealth

The limestones formed during jurassic and cretaceous periods have created an spectacular mountain range, with a wide variety of structures, fossils, mines and even the remains of Euskadi’s only glacier.

Beauty underground

Aralar is like a sponge, as the water enters the subsoil and comes up all year round at natural springs such as Pardelus. Aralar’s inner part is a labyrinth of caves, underground rivers and chasms as deep as 600m.

Between beech woods

A fourth or Aralar Natural Park’s area is covered in beech trees. But the forests are very diverse, creating spectacular landscapes.




A place where shepherding is still very much alive

The middle part is used as pasture, widely used by a big “latxa” sheep herd. Shepherding has existed here for thousands of years, proof of this activiy is the concentration of megalithic monuments: dolmens, tumulus, cromlechs and menhirs.

The three entrances to the Park

Aralar Natural Park has three entrances in Tolosaldea: Amezketa, (San Martin), Abaltzisketa (Larraitz) and Bedaio.

Aralar is often visited by mountaineers thanks to all the different options it offers, although the climb of its mountains requires some practice. Here we’ll highlight some of the most interesting features.




Arritzaga, Euskadi’s only glacier valley

Arritzaga valley in Aralar keeps the remains of Euskadi’s only glacier. Here in the past, at an altitude of almost 1,000m, is where Buruntzunzin mines were located, with its remains still visible. The stream forms very particular natural pools at different heights.

Ausa Gaztelu, the remains of a castle

Named after a medieval castle that used to be at the peak, with the purpose protecting the Erinio, Gipuzkoa and Navarre Road. There are still remains of the 19m diametre circular building at the peak, where a family of ‘jentikak’ (creatures of the Basque mythology) used to live. The view with Txindoki as background is outstanding.
