Travesía translates to "journey" or "crossing", but it often implies a long, arduous, or adventurous trip.
In this song, the singer uses travesía to describe his journey back to his childhood home in the plains of Arauca. It evokes a sense of nostalgia and the significant distance, both physical and temporal, he is covering to revisit his roots and memories. It's more evocative than a simple "trip".
This song is a beautiful journey back in time, as the singer, Juan Farfán, takes us on a trip through the Araucanian plains of Venezuela. He's revisiting the places he grew up, the "caminos que se me están olvidando" [roads I'm forgetting], almost as if he's worried he might die before he gets to see them again. It's a nostalgic look at his childhood and the start of his career.
He remembers specific spots like "rincón de los caracaros" [corner of the caracaros] where he worked hard with his parents, and where he took his "primeros pasos como cantante de llano" [first steps as a plains singer]. He even recalls a specific "banco" [bench] where he had a crush, saying "todo parece que fue ayer pero ya hace muchos años" [everything seems like yesterday but it's already many years ago]. It's a heartfelt tribute to his roots, his family, and the simple life that shaped him into the artist he became.
