Visit Dinh Cau Rock (Dinh Cậu), an iconic landmark of Phu Quoc located at the mouth of the Duong Dong River next to the fishing harbour. This small, picturesque temple dedicated to the Goddess of the Sea sits atop an unusual rock formation accessible by a short flight of stone steps. Local fishermen often pray here for safe voyages.

While interesting culturally, Dinh Cau Rock and Temple Phu Quoc is most famous as one of the best sunset spots Phu Quoc. Watching the sun dip below the horizon with views of the colourful fishing boats returning to harbour is a classic Phu Quoc experience.
