This study aims to develop tourism development priorities and marine tourism policy directions in Pariaman City. To assess the suitability of marine tourism land, 10 indicators are used, namely water brightness, beach type, beach depth, substrate, current speed, live coral cover, disaster proneness, and accessibility. The analytic hierarchy process approach, considering four criteria; government support, tourism industry, community support, and land availability-is used to determine the tourism potential index. Findings from 10 observation points reveal that two observation locations were very suitable (S1) for marine tourism, four fall into the appropriate category (S2), and the remaining 4 are marginally suitable (S3). Based on the tourism development potential index, the top three priority observation points are P5, P6, and P7. The results indicate that observation point P6 has the highest value, while observation point P2 has the lowest. The prioritised policy direction strategy for developing marine tourism in Pariaman City includes three subelements: A6 (attracting investors for marine tourism development), A5 (increasing the frequency of tourist attractions), and A1 (improving beach cleanliness).
