Beautiful, magical place. The final stretch is difficult to access. Not suitable for everyone. Very steep slope and lots of loose stones. The ground is also quite rocky, so on rainy or humid days it has to be very slippery. Otherwise, it is beautiful and you can take it easy and enjoy it.

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.
