3. Unmissable highlights of an excursion to Da Dia Reef
3.1. Unique geological formations
Da Dia Reef features an extraordinary landscape that captivates visitors with its unique rock formations and ever-changing colors throughout the day. According to scientists, the basalt rocks at Da Dia Reef were formed nearly 200 million years ago due to volcanic activity in Van Hoa Plateau about 30 kilometers away.
Spanning over 50 meters in width and 200 meters in length, the reef appears from a distance like a giant honeycomb, with its mysterious black stones standing out against the blue sky and sea. As you get closer, you will be astonished by the sight of tens of thousands of stone columns with hexagonal, square, or circular cross-sections, which are perfectly stacked atop one another. Some of these columns rise straight up, while others are laid out flat or tilted.
