Buruntza is a minor mountain in the Basque Country (Spain) 12 km south of San Sebastian. Several towns lie at its foot, namely Andoain (S), Lasarte-Oria (N) and Urnieta (E). The mountain stretches out in a north-east to south-west disposition, starting at the pass of Azkorte (hermitage) on to a quarry at the southern end, by the neighbourhood Buruntza in Andoain. The mountain rises opposite to Adarra (E) and stands in turn to the east of the mountain Andatza. There is a big cross fixed at the summit.
