Na-hkilek
Nā-hki-lek or Na-hkilek is a river village on the Salween River in Shan State of eastern Burma. It lies on the confluence of the Salween and the Nam Pang River. A few miles north beyond the junction is said to be "a strange whirlpool, at the place the river is in a gorge between limestone cliffs, which fall smooth and precipitous to the water's edge."
It is located about 120 km east of Kengtung.
