This study aimed at uncovering the influences of coastal resort vacationers' environmental and climate satisfactions on their perceived destination restorative qualities (PDRQs), to provide a new perspective in understanding how the environment and the climate impact tourists'mental and physical health and restoration, as well as a better understanding of PDRQs. The data were collected via a questionnaire survey in two typical coastal resorts in Sanya City, Hainan Province Dadonghai and Yalong Bay (N=527). Applying the principal componentbased structural equation modeling technique of partial least squares (PLS_SEM), the results show that both vacationers' climate satisfaction and environmental satisfaction significantly and positively influenced their PDRQs (compatibility, extent, mentally away, physically away, and fascination). Implications for the sustainable development of resort destinations are provided. Specifically, for companies and managers in coastal resort destinations, improving vacationers' satisfaction with the environment and the climate through publicizing information on the environmental and climate conditions and protecting the natural environment would facilitate vacationers in experiencing more of the restorative qualities, and thus having a deeper mental and physical restoration. Finally, the increase of perceived destination restorative qualities would help a resort destination to strengthen its competitive edges in the tourism market.
