Accessibility is one of the key factors influencing tourists’ decisions to visit a destination. The Sangiran Early Man Site, as an educational tourism destination and a world cultural heritage site, needs to be supported by adequate accessibility in order to increase tourists’ interest in visiting. Studies that specifically examine the influence of accessibility on visiting decisions in cultural tourism destinations based on world heritage sites, particularly the Sangiran Early Man Site, are still limited. This condition indicates a research gap that needs further investigation. This study aims to analyze the effect of accessibility on tourists’ visiting decisions to the Sangiran Early Man Site. The research method used is quantitative, with a sample of 100 visitors. The sample size was determined using the Slovin formula. The collected data were analyzed using validity tests, reliability tests, normality tests, simple linear regression analysis, and hypothesis testing using IBM SPSS Statistics 26 software. The results show that all research instruments are valid and reliable, and the data are normally distributed. The results of the simple linear regression analysis indicate that accessibility has a positive effect of 0.189 on tourists’ visiting decisions. Hypothesis testing proves that this effect is statistically significant, with a value of 0.015 < 0.05. Therefore, it can be concluded that the better the accessibility provided, the higher the tourists’ decision to visit the Sangiran Early Man Site.
