Adapted questionnaires were translated into electronic survey form were used to measure the extent and establish the relationship between residents’ perception on tourism development, value orientation, and destination attractiveness to sustainable tourism using the mean, Pearson r, regression, and structural equation modeling as statistical tools. The study revealed high levels of residents’ perception on tourism development and sustainable tourism, while value orientation and destination attractiveness level was very high. Results also show that residents’ perception on tourism development, value orientation, and destination attractiveness have a significant relationship across all dimensions of sustainable tourism, with residents’ perception on tourism development as the greatest influencer for sustainable tourism. Finally, structural equation modeling determined the best fit model characterized by the direct influence of residents’ perception on tourism development and value orientation on sustainable tourism with positive perception, support to tourism, biospheric value orientation, and altruistic value orientation left as indicators. However, destination attractiveness proved to have a negative influence on sustainable tourism.
