The Ruta 3 Reyes is a tourist destination that unites the towns of Alcañiz (Aragon), Morella (Comunitat Valenciana), and Tortosa (Catalonia) under a single proposal. The geographical proximity between them has created important links over the years, including legends such as the one that gives its name to this route. But what does the Ruta 3 Reyes offer? Nothing more and nothing less than imposing castles, robust walls, beautiful churches, underground passages, precious landscapes, great rivers, and a lot of history through which to discover the treasures of the land of the natural Gothic.
