Aizkorri-Aratz Natural Park

One of the highest peaks in the Basque Country at 1551 metres.

Be sure to visit the tunnel of San Adrián, a cave that served as a natural passageway to the neighbouring Alava. This area is steeped in legends and spectacular views. Tucked inside the tunnel is a small chapel, an essential landmark on the Way of St James. The ascent from the Arantzazu Sanctuary to the Urbia Field is another must for hikers. Two 'parketxes' or interpretation centres, will provide you with all the information you need: Parketxe de Andueza Zegama. 943 80 21 87 Parketxe de Arantzazu Oñati. 943 782 894
