On this trail we will visit the slopes that cover the eastern part of the ravine where the river flows. Then we reach a hill where we approach the area of Otsondottiki and take advantage of the Camino de Santiago de Baztán to return over the Ikatzateko Borda stream. At the end we visit the Fuente de los Frailes, where we can rest for a while before returning to the nearby village. A beautiful trail to get to know closely the ways of life, vegetation and forests that carpet these valleys.
