Starting in Beasain, you will get through Aralar’s Natural Park, crossing Lazkaomendi and Enirio.
The ascent is long and hard, especially the final stage, close to Igaratza. Once there, it starts a pleasant downhill to Lareo reservoir. Get down the road to Ataun, where you will have to go up a short but steep slope, into the town of Olaberria. From here you will be getting closer to Beasain, seeing the beautiful caseríos of the area, and going down passing Indar’s factory and Igartza Monument Complex.
