OverviewThis is the shortest route to climb Txamantxoia.
You will have to get there from Pamplona or Huesca, the biggest closer cities. Follow the road linking both of them (N-240) until the crossing of Venta Carrica. This is a crossing about (will check) sixty kilometres from Pamplona, where you can find a petrol station and the beginning of the road to Sigüés / Salvatierra de Esca / Roncal (signal of ski resort of Arette as well). Follow this road (NA-137) for 13 km, until Isaba. After Isaba keep going north (NA-1370) for three more kilometres and turn right on the crossing marked as (Zuriza /Ansó). This small road (NA-2000) will take you across the valley of Belabarce and to the camping area at Zuriza, under the Sierra de los Alanos. When you finish coming down from Belabarce (that will be some thirteen kilometers after Isaba), turn left for the camping area and drive around it until the end of the road. It is not in a very good state, so don't drive fast. You will see the dirt roads to Barranco de las Eras and Barranco de Gamueta to the right, but pay them no attention. Keep going on the main road until a final turn right, around a rocky hill, sets you on the small flat valley known as Plano de la Casa and the mountain hut of Linza. A few of meters before the Hut is the track closed with a barrier.
