Da Dia Reef

An extraordinary basalt coastline

Tucked away at the end of An Ninh Dong commune, Tuy An district, Da Dia reef is a beguiling natural wonder of Phu Yen with black basalt rock formations rising along the sea. It is only 21 miles away from the city center and the drive itself is relaxing with gentle sea breezes and romantic hometown scenery.

The majestic basalt rock bed surrounding the sea is Da Dia reef's unique trait, which is hard to find elsewhere in the world. It was recognized as a National Heritage site in 1998. Coming to Da Dia reef, tourists get astounded by countless black polygonal rocks stacking up as a result of volcanic eruptions that took place millions of years ago. They form a pitch dark seaside wall that looks like piles of plates.

Its name Da Dia, which means rock plates, describes well this geological characteristic. Looking from afar, the rocks rising from the sea resemble a massive honeycomb. Its black color draws more attention to the vibrant turquoise shade and the crystal clearness of the water, creating a harmonious yet unique fusion. Bring good shoes to climb to where the rocks meet the sea. A drone would come in handy if you want to capture this extraordinary vista from above. Da Dia reef gets quite crowded from May to July due to tourism peak season but if you set out early you can still get amazing pictures. The entrance ticket costs just 1 dollar so this place is budget-friendly as well.

If you are seeking serenity, unique landscape and instagrammable photos, Da Dia reef is the first place to see in a Phu Yen tour.
