After reaching this peaceful and green hill, where it is sometimes even possible to enjoy horses around, we can have a panoramic view of the area in which, of course, the Mugarra stands out right next to it, imposing itself over the area. If you are going to climb Mugarra, it is an ideal point to stop to regain strength before the last stretch.
