The Legend Behind the Name
Hang Mua takes its name from a legend about the Trần Dynasty king Trần Thái Tông, who came to this valley to watch court performers dance (múa) in the cave at the mountain's base after establishing Am Thái Vi pagoda nearby.
The Climb and the View
Today the cave is a minor footnote; the draw is the 486 stone steps carved up the side of Ngọa Long peak to a summit at 200 metres, from which the entire Tam Cốc valley unfolds. The Ngô Đồng River threads through the karst below, rice fields extend in every direction, and the distant limestone ridges of Tràng An mark the horizon.
The summit has two focal points reached by a junction midway up: left leads to a giant dragon statue jutting from the cliff face; right leads to a five-tiered Buddhist stone tower. Both see the same valley panorama from slightly different angles.
Harvest and Lotus Season
In May and June when the rice harvest turns the fields gold and the lotus ponds at the base bloom simultaneously, Hang Mua produces one of the most reliably photogenic landscape combinations in northern Vietnam.
