Ecotourism is an alternative to conventional tourism where tourists can enjoy natural scenery by prioritizing conservation aspects as a form of expressing responsibility to the environment. There are several popular ecotourism sites in Indonesia, one of which is Banyuwangi Regency, which was the world winner of the 12th United Nations World Tourism Organization (UNWTO) awards. This study was conducted to analyze the factors that influence the behavioral intention of tourists to ecotourism at Banyuwangi Regency. By knowing the factors influencing behavioral intention, tourism managers and local governments can gain better insight into strategies that can be adopted to increase consumers’ positive intention toward ecotourism. This research was conducted with multivariate structural equation modeling (SEM), and twelve hypotheses were tested. A total of 344 respondents participated. Six accepted hypotheses were revealed. A positive and significant influence was found on the subjective norm and destination image variables on ecotourism behavioral intention. The analysis found a positive and significant effect between ecotourism self-identity and subjective norm variables. Other results found that the biosphere value had a positive and significant effect on the environmental attitude, and the future time perspective and destination image variables were found to have a positive and significant effect on the environmental concern variable. Most respondents in this study admitted that they are individuals who have a love for nature and are willing to dispose of their garbage in its proper place. Further theoretical and practical implications were described.
