<![CDATA[Background: The Oya River is a nature-based tourism destination in Imogiri, Bantul, Yogyakarta. Visitors can take part in activities such as swimming, canoeing, and camping, all of which carry a high potential risk. Unsafe actions are still frequently observed, including swimming without a life jacket, jumping from cliffs, canoeing without a life jacket, and disregarding the rules set by the management. Tourist safety behavior therefore needs to be improved, in part by strengthening the factors that drive its formation. This study aimed to analyze tourist safety behavior based on the antecedent–behavior–consequence (ABC) theory at the Oya River tourism destination. Method: A qualitative approach with a descriptive method was used. Data were collected through interviews and observation, with the researcher acting as the main instrument. Informants were selected purposively and comprised tourists and officers at the Oya River tourism destination. Observation was carried out using a checklist based on the ABC theory. Results: Most tourists at the Oya River tourism destination already displayed safe actions. This was supported by the efforts of the tourism officers, which satisfied the antecedent, behavior, and consequence factors that reinforce safe behavior among tourists. The remaining shortcoming is the absence of clear consequences from the destination management. Conclusion: Tourist safety behavior is influenced by the main components of the ABC theory. All three components need strengthening, particularly the consequence component, through the consistent enforcement of sanctions and the provision of rewards]]>
