The cave is located atop Phuong Hoang (Phoenix) Mountain. Visitors spend half an hour climbing up 100m to the cave. Seeing from its foot, the mountain has the shape of two laying phoenixes. Legend goes that a long time age, there were a couple of phoenixes living very happily and they were born two eggs. Everyday, that father bird looked for food and the mother bird sat the eggs. One say lured by a new flock, the father bird forgot his task and did not come back. Until he remembered his task and returned to the nest, his wife had been transmuted into a rock. Feeling regrettable , he laid on the opposite mountain, looking toward the nest with the hope that his wife could revive. Waiting hopelessly for a long time, he was also trans-muted into stone. Since then he mountain has been named Phuong Hoang.
Reaching the mouth of the cave, visitors can see the landscape of this land. The cave includes 3 layers: the upper layer is Doi (Bat)
Cave, the central is Sang (Light) Cave, and the lower is Toi (Park) Cave. The Light Cave is spacious and well-ventilated. The stalactites in the cave litter fancifully thanks to the light from the three main mouths of the caves. Visitors can freely imagine the forms of these stalactites such as a mother is carrying her son or her back on the way to the field, ancient people are hunting wild animals, and lanterns.
At the foot of the Phuong Hoang Mountain, there is Mo Ga (Chicken’s Beak) Stream Cave. Its entrance is 100m wide and there is a stream that flows out from the cave. In front, there are many rocks and small natural pool. The water is clear and the landscape is fantastic.
The complex of Phuong Hoang Cave and the stream in Mo Ga Cave were listed as National Site by the Government in1994.
