The Serra da Bodoquena is the region in the state of Mato Gros¬so do Sul, Brazil in which the municipality of Bonito is located. This municipality is the primary calling card for tourism in the state and is one of the most developed areas of ecotourism and speleotourism in the country. The tourism there is entitled ecotourism, and is designed to be sustainable. The present case study focuses on the ecologically sustainable aspects of the spe¬leotourism practiced there, especially the proposals for tourist carrying capacity adopted. The results and discussion provide suggestions for the adoption of a different formulation of car¬rying capacity focusing on both operational and quantitative aspects. Ecologically sustainable speleotourism in the Serra da Bodoquena should be possible as long as new proposals limit¬ing visitation are adopted which conform to technical environ¬mental management procedures and consider the interests of local stakeholders.
