Abstract Tourism activity affects the cave's physical environment in several ways, such as damaging speleothems, altering the cave structure for ease of access, and the shifting of cave microclimate. Nevertheless, it is less clear how the pressure of touristic activities affects the cave fauna. This study aimed to investigate the effects from tourism activities on the cave invertebrate fauna from Gruta de Lanquín Cave (Alta Verapaz, Guatemala). For this, quadrats were placed throughout the cave, where invertebrates were sampled and substrate features were measured. Results showed that the community structure differed among touristic and non‐touristic areas of the cave and the troglobitic species are structured differently than the rest of the invertebrate community in the cave. It was detected that the pathways designated for touristic use have different substrate features than their adjacent areas. In order to maintain the conservation of the invertebrate species, several management recommendations are provided, such as determining a well‐established walking path that avoids cave microhabitats and the maintenance of a supervised guided tour.
