The characterization of a geothermal system requires the integration of geological, geochemical and geophysical studies. The purpose of this reserach is to contribute to the knowledge of the geothermal system of Doña Juana Volcanic Complex through the hydrochemical analyses of hot springs and fluid-rock interaction, together with conceptual hydrogeological modeling. In this study, we use the chemical data of the water was obtained from the National Inventory summary of hot springs by the Geological Survey of Colombia and was divided in two groups named Doña Juana system and Las Animas system, together with a preliminary hydrogeological model, to highlight the recreational use of geothermal springs along the Doña Juana Volcanic Complex National Park (e.g. Tajumbina spring). The general conclusion is that both techniques are suggesting a mixing process between geothermal fluids and meteoric waters where related to the upflow with a reservoir temperature around 180 °C, showing a high temperature system in which the fault systems apparently play an important role in the flow of the geothermal fluids. Such characteristics are also adding to the standard attractions offered by this National Park natural Geothermal resource in Tourism as a possible economical sustainable answer, that may support the implementation of the pace agreement in Colombia, involving the women empowering in the rural processes in the Northern Andes. Therefore, this place can be developed into a unique tourist destinations with a high geoheritage value.
