This study aimed to explore seasonal calendar, and investigate participation model, tourists' experiences, as well as interpretation theories in the context of creative tourism in environmental issues from creative tourism entrepreneurs' perspective in Thailand. 10 environmental activities from 10 creative tourism entrepreneurs were purposively and snowball sampled. Data were collected by using in-depth interviews together with voice and digital photo recordings, note taking, observations, and GPS application records. Data were then analyzed by content analysis, and triangulated with different data collection methods. Results advised an optimum seasonal calendar of creative tourism in environmental issues in Thailand, and also indicated that almost all the creative tourists participated in all types of participation model. Active participation was the key at creative tourism activities that made creative tourists reach experiences of cognitive, affective, and sensory kinds. In addition, participation in sharing ideas brought added value in both monetary and non-monetary terms. Personal and non-personal interpretations were also used, and especially emerging technologies in communication were found to influence participation in sharing creative ideas via websites and social media, which has not been reported in earlier interpretation research findings.
