Adarra (short for "Adarramendi", meaning 'mount of horns' in Basque) is a mountain south of the city of San Sebastian in the Basque Country. It is a popular peak with the local residents. The mountain is flanked on the north by the minor summits of Oindi or Onddi (, 545 m) and Onddo (781 m) to the south, all of them located at the top of a long mountain range of modest height between the Urumea and Leitzaran valleys, which extends south right to the edge of the Navarrese town of Leitza. Geology and vegetation The mountain stands on the westernmost end of the Pyrenees. Outcrops of slate, sandstone, conglomerates, red silt and other materials can be found on the peak, largely from the Paleozoic Era and Mesozoic Era. On its eastern slopes, patches of indigenous forest and vegetation abound, while on the western side (especially on the way down to Leitzaran) pine tree used for logging prevails. Grassland strips used for grazing sheep and horses interspersed with forest are common. Prehistoric monuments The mountain and the whole area show several examples of megalithic art, for the most part small monuments which are common on the Atlantic basin of the Basque Country, dating from the Neolithic and Bronze Age. 34 stone circles, four dolmens, three cists and two menhirs can be found locally, dating from the megalithic era. According to the anthropologist Jose Miguel Barandiaran, legend states that the Basque mythological giant Sanson got angry with a crowd of people dancing in Arano, so he intended to kill them. Yet when he was about to hurl a stone at them from the mountain Buruntza, he slipped on cow dung and the stone fell short on this spot, resulting in the current stone of Eteneta The ancient remains of a man buried with a dog and lamb were unearthed in a local cavern, dating from around 4,000 BC. The surroundings of the cavern are currently somewhat in a poor condition due to a polluted stream nearby. Events Early on New Years Day, people of all ages, the bravest of whom had been celebrating the night before, pour into Adarra to see the sunrise or just to start the year in a good way. Some people may carry music instruments, including a trikitixa, tabor and pipe, etc. to enliven the atmosphere. Access points and trails Besabi The main access point lies at
