In spite of going up the Puerto de Urbasa to the high part of the Sierra, this route can be classified as of medium physical difficulty since the presence of asphalt and concrete is important and, except for this first ascent, the rest of the route does not present great difficulties.
We could also call it the route of the villages of Las Améscoas since, except for Larraona and Urra, the rest are included in this route. Why the name Lezarugi, because it is the most popular point of the campsite, which we will reach after ascending Urbasa and crossing the Raso, and also because it is a very charming corner in the middle of the Sierra.
