A boy and his grandfather spend the afternoon together. The grandson wants to climb the tree, but doesn't think he will be able to. He soon discovers that you don't have to be especially strong or big to climb to the top of the tree. The ants and lizards can climb it! The boy realizes that every tree has its own path and it is sometimes necessary to watch and wait patiently for it to be disclosed. Los caminos de los árboles es un álbum escrito por Pep Bruno y magistralmente ilustrado por Mariona Cabassa. Está publicado por la editorial La fragatina, siendo éste el título que inaugura la colección "Lo mullarero".
