Perceptions of Cipó Mountain Range National Park (MG, Brazil) Visitors for Geotourism
Published 2018-08-01“…The results show that: visitors are tourists (70%); do not seek the geology (62%) of the park, being the main motivations “waterfalls” (24%) and “contemplation of nature” (12%); believe that knowledge of geology helps in understanding the landscape (32%); relate geological heritage to rocks and relief (28%) and that their importance is due to life on Earth (24%), that their degradation diminishes the attractiveness of the landscape (96%) and they are interested (98%) in knowing more, in particular geology and geomorphology (58%); do not know what is geotourism (46%) and of these believe that the park can be conserved through geotourism (96%); do not know what a geopark is (66%) but correlate it to the protection of geological heritage (35%) and consider that geopark benefits include preservation, scientific research and education (65%). …”
