When I set foot on the ancient rock rapids at Da Dia stream in Van village, I couldn't help but be amazed by the majestic beauty that nature bestows on the land of Gia Lai. Located in the heart of the Central Highlands, the ancient rock rapids appear like a perfect picture, where rocks are stacked on top of each other, winding along both sides of the clear stream. It is not only a precious geological heritage but also a silent account of millions of years of history of formation and change of land and sky in the Central Highlands.
