The present work analyses the uniqueness of the Camino de Santiago (or The Way of Saint James), a religious and medieval pilgrimage route that has become a contemporary tourist product with a deep power of attraction. To this end, a series of factors that have contributed to the change and renewal of its nature are detailed. Firstly, we explain the public promotion of the Camino as a catalyst for a process of physical construction of a pilgrimage route. Secondly, we focus on studying the Santiago pilgrim’s motivation, as it is also a relevant factor in determining slow mobility in urban and rural areas. Finally, these factors interact with each other and result in the definition of the pilgrim as a new tourist who walks or rides a bicycle. All of the above leads to consider new social and territorial dynamics.
