Tourism development plays a crucial role in regional economic growth, especially through optimizing the potential of local destinations. Gajah Mungkur Reservoir in Wonogiri is one such destination that attracts visitors through its natural beauty, facilities, and cultural uniqueness. This study aims to analyze the influence of Electronic Word of Mouth (e-WOM), facilities, and attractions and uniqueness on tourists' decisions to visit the Gajah Mungkur Reservoir. A quantitative method was employed using multiple linear regression analysis. The results indicate that all three independent variables—e-WOM (β = 0.416; p = 0.006), facilities (β = 0.265; p = 0.048), and attractions and uniqueness (β = 0.371; p = 0.041)—have a positive and significant effect on tourists' visiting decisions. The F-test also confirms that these variables simultaneously have a significant influence (F = 12.645; p < 0.05). The Adjusted R² value of 0.416 shows that 41.6% of the variation in visiting decisions can be explained by the model. These findings suggest that enhancing digital promotion, improving tourist facilities, and emphasizing unique local attractions are key strategies to increase tourism competitiveness and visitor interest.
