Tourism is one of the worlds fastest-growing sectors and is considered a major contributor to environmental changes and vulnerable to climate change (CC). Quan Lan Island, one of the popular destinations in the region, is facing higher tourism development and is vulnerable to CC and environmental impacts resulting from tourism development. Although the tourism industry on the island has not developed strongly, tourism activities on Quan Lan Island are often affected by climate change and sea level rise. Therefore, this study aims to analyze the relationships between tourism and CC and recommend strategies for enhancing governance compatible with the coastal environment and changing the climate. The study applied a mix of qualitative methodologies. Primary data were collected basically through a semi-structured interview, stakeholder group discussion, and site observation, together with secondary data. The explored relationships prove that the tourism destination is developing in different directions. The tourism sector faces mostly different CC-related impacts and adaptations. To enhance the relationships, proper management of tourism infrastructure and services is suggested for CC and the environment.
