Once Islas is a new eco-cultural tourism attraction which opened to public last July 2018. It is composed of 11 islands along the Moro Gulf, which belong to the barangays of Panubigan and Dita in Zamboanga del Sur. Of these islands, 4 are opened to the public and can be reached by registering at the office of Barangay Panubigan. These are Bisaya-Bisaya, Sirommon, Baung-Baung and Buh-Buh. The first three are ideal for swimming and snorkeling, while the last one is for cultural touring.
