Phu Quoc is called the island of "99 mountains" because of its many sandstone chains gradually descending from the north to the south. The longest one is Ham Ninh which stretches for 30 km along the eastern edge with its highest peak called Mt. Chua (603m).

Trips to Phu Quoc can be made all year round, but the best time is dry season when the sky is always sunny, clear and blue.
