The present dissertation deals with the applicability of geomorphologic cartography and geodiversity to the geotourism of Tijuca National Park, located in the Municipality of Rio de Janeiro (RJ). The work has as objective the construction of geomorphological mapping and characterization of the geodiversity of the Park, providing proposals for application to geotourism. The study area is inserted in the Tijuca Massif in the upper course of the Tijuca river drainage basin (Sector A- Tijuca Forest). The methods used were based on geoprocessing techniques and field work, divided into geomorphological mapping, geodiversity index, geological mapping and geodiversity site inventory. The geology is characterized by the presence of orthoderivative and paraderivative gneisses, quartzite and granite. The relief is represented by rugged mountains, high hills, hills and thallus ramps, colluvium and alluvium. The geomorphological map was based on the analysis of the topographic position index, which generated 10 classes, providing details about the slopes. The geodiversity index, represented by kernel density, provided the spatialization of the variety of abiotic elements, alternating between very low and very high. The geological map presented the details of the lithologies found in the Tijuca River basin, highlighting the large presence of quartzite of the São Fidélis Group and orthogneiss of the Rio Negro Complex. A total of 28 geodiversity sites were described, providing much useful information for the promotion of geotourism within the Park. Most of the visitation sites in the upper Tijuca River basin have a geological and geomorphological character, but information on geodiversity is not available. The creation of signs, folders, maps and dialogues with visitors and residents of the neighboring areas of the Park will contribute to the public awareness and impulse of the scientific dissemination.
