The initial section of the route, until reaching the bridge that crosses over the Besiberri ravine, takes place with an average slope and along a comfortable and well-trodden path. From the bridge, the path becomes noticeably steeper, presenting areas of steep slope, and the terrain becomes more rocky; however, it can be traveled without too many difficulties.
