Doi Nang Non consists of a long hill tract that lies on the west side of the highway between Chiang Rai and Mae Sai.

The greater part of the range is in Mae Sai District, extending west and southwest of Pong Pha along the border with Myanmar.

[2] The mountain range is an unusual land feature when seen from certain angles as its silhouette takes the shape of a reclining woman with long hair.

[14] Food and medical supplies were delivered but a three-hour-long journey, continued rains and mountainous terrain above the cave delayed their escape.

The distraught princess stabbed herself to death and the legend says her blood became the water that flows through the cave, while her body is the surrounding mountains, said to look like a sleeping woman.

[18] Local tour guides joke that Doi Nang Non would be "the highest mountain in the world", if only the supposed lady would get up and stand on her feet.
