Sustainable tourism is tourism that considers the future and that can contribute to the survival of the industry. Regrettably, sustainable tourism has not been fully integrated into society at the anticipated magnitude. This study was aimed to identify any factors that enable sustainable tourism development. The study employed a quantitative approach and used nonprobability sampling with a sample examination of as many as 200 respondents. The data was collected through online surveys using a Likert scale. This study applies to external and internal models completed using structural equation modeling 3.0. Based on the research results and analysis, it can be concluded that variables such as tourism perception, positive impact, experiential satisfaction, destination image, and motivation have a positive and significant influence on the sustainable tourism development attitude, and it is possible to conclude that all hypotheses are accepted. This research is expected to contribute to developing knowledge about how tourists can preserve natural resources and contribute to future tourism development, especially from the perception of tourists from different countries. Thus, this research provides valuable contributions in filling the gaps in knowledge about the real attitudes of tourists toward preserving and contributing to environmental sustainability to develop future tourism.
