From the top of Muniketa or Montecalvo, there are exceptional views and you can see the sea and Urdaibai on one side, as well as the Duranguesado on the other. Muniketa is a dispersed neighborhood with several typical hamlets and until 1848 it was the main route of communication to the south through Durango. That year the Autzagane road was improved. In Muniketa is the Astei agrotourism, a rehabilitated farmhouse with restaurant service from where we can perfectly see a slope of Mount Oiz and Goraño. From Artatza, the ascent is a 3.7-kilometre climb with 261 meters of positive elevation gain, 12 beautiful horseshoe curves and a very regular slope of around 7%. From Muxika, the ascent is 9 kilometers and a total of 382 meters of positive slope. More info at: https://www.muxikakoudala.eus/es-ES/informacion-cultural/Barrios/Paginas/Muniketa.aspx
