Las Peñas de Haya is a mountain in Spain in the Irun’s suburbs. The french noun about this mountain is translate by “les trois couronnes”.
These three summits are:
Irumugarrieta, 806 m
Txurrumurru, 827 m
Erroilbide, 837 m
The mountain ridge is the border of “La Peña de Haya” Natural Park or in Basque “Aiako Harria”, declared preserved natural area since April, 1995. This park rests on the oldest materials of Basque country , the granite rock which began to form 270 million years ago.
The trekking to reach the three summits is really adventuress, regulated by steep trails like-looking more a climbing rather than a hikking. The scenery changes as you travel along. Besides, I advice you to wear a good trekking or hiking shoes and not city shoes!
To do 15 kilometers, we needed 5 hours walking!
Only reserved to harden people!
