At the base of the H'Chan hydroelectric power station lies an ancient rock formation in De Ar Commune, Mang Yang District. The power plant is situated alongside the Ayun River. The rock field is about 45 kilometers from the center of Pleiku, the capital of Gia Lai Province. There are several steep and winding stretches on the concrete access road.
This rock formation is about three hectares large. A forest station manager in the area said that it is currently the dry season so tourists can easily visit the rocky beach. However, visitors should avoid climbing the extremely slick high areas.
The hexagon-shaped rocks are either perpendicular to the ground or stand upright. The rocks here have eroded under the immense pressure of the Ayun River, resulting in their strange shapes.
Nguyen Quang Tue, head of the local Department of Culture, Sports and Tourism, said that after discovering the valuable rock field, he studied and consulted with geological researchers. "The ancient rock fields in the Central Highlands are all millions of years old," he said.
