This study focuses on sustainable sea turtle tourism development in small islands, focusing on a case study on Gili Trawangan, Indonesia. All species of sea turtles are globally endangered, largely due to impacts of unsustainable tourism development. Gili Trawangan is an island dependent upon a flourishing marine tourism industry. It is crucial to determine stakeholder perspectives to reveal barriers and influences in tourism development to help promote sea turtle conservation and protect the livelihoods of local communities. The study was conducted in 2010 to examine an opportunity for stakeholder collaboration to promote conservation in sea turtle tourism. The study applied qualitative data methods to deepen the knowledge on stakeholder collaboration in the development of sustainable tourism in small islands. Key findings provide insight on what influences conservation through sea turtle tourism, and recommendations to promote sustainable tourism development in other small islands facing similar situations.
