Larraitz (Abaltzisketa) and Lizarrusti (Ataun) are the two gateways to this Park. We are in one of the most important mountainous areas in terms of extension, altitude, land use and natural values of the Basque Country, as well as being one of the most frequented. Framed between the regions of Goierri and Tolosaldea, it is a landscape reference of the first order, with the emblematic summit of Txindoki (Larrunarri).
