Adarra

Adarra (short for "Adarramendi", 'mount of horns') is a mountain south of the city of San Sebastian in the Basque Country much appreciated and popular with the donostiarras and other neighbouring inhabitants. It is flanked on the north by the minor mount Oindi or Onddi (IPA:, 545 m) and Onddo (781 m) on the south, all of them located at the top of a long mountain range of modest height establishing the division between the Urumea and Leitzaran valleys, which extends south right to the vicinity of the Navarrese town of Leitza.
