When we think of an affective geography, where the world is the stage of a concrete encounter between its sensitive elements and the human being, we understand the landscape as an experience, experienced in a unique way by each person. In this way, the perception is fundamental in the construction of the landscape and the geographicity. Therefore, in order to think and understand the world from the experiences of human beigns in it, we establish a dialogue between geography and phenomenology. We understand that through the affective relationships between the human being and the landscape, there are possibilities for new ways of geographical doing and thinking. For that, we use the Petrópolis-Teresópolis Crossing as the study area, a mountainous environment, locate in the Região Serrana of the state of Rio de Janeiro. The present work, entitled Perceptive trails: the Petrópolis-Teresópolis Crossing , intends to evince and problematize how the geographic science can help in the understanding of the relations established between the various forms of spatial sensitivity. The methodology used was that of narrative interviews, in wich we sought to understand what motivate the persons to make the Crossing, so that it was possible through their reports to know their perceptions about nature and to record aspects of this experiences that are important to them. We understand that the geographic perception is reflected in the way that people relate to the Crossing and, in this way, we intend to contribute to the appreciation of the Geography and Geomorphology that is experienced and is taught.
