In the Philippines, tourism is considered one of the significant sectors as it plays an important role in the economy. The purpose of the study is to provide a tourism inventory and tour trek design towards community-based tourism in Siruma, Camarines Sur, Philippines. Specifically, the study aims to identify potential tourism attractions, conduct site evaluation and site prioritization and propose a tour trek design to promote community-based tourism. The methodology applied in the study has three major phases: preparatory activities; field activities, and a validation workshop. Focus group discussion, interviews, site visits, and site evaluation were conducted to achieve the objectives of the study. Results revealed that Siruma has numerous potential destinations, including beaches, sandbars, islands, rock formations, hills, and other landmarks. The site evaluation and prioritization show that beaches in Barangay Pinitan and San Ramon and the Tinalohungan hills, shared by Barangay Bagong Sirang and Barangay San Andres, are the top three potential tourism destinations. The proposed tour trek design based on the inventory, site evaluation, and site prioritization highlights the vast untapped natural resources and unique heritage of Siruma. Furthermore, the study shows the need for the government to create ordinances and guidelines to protect and promote natural resources and local culture, as well as improve infrastructure and transportation accessibility for the safety of tourists and the community. The local government unit and the community acknowledge the significance of tourism development and the necessity for all stakeholders to participate towards sustainable community-based tourism.
