It was once the provincial capital. Mae Chan's name lies in its silver and tribal handicrafts. Once officially unrecognized by the Thai government, Doi Mae Salong is a Chinese KMT (Kuomintang) area renowned for its natural beauty and unique Yunnanese culture. Besides the Chinese 93rd Infantry of the Kuomintang, several other ethnic minorities have settled down in the region including the Tai Yai, Tai Lue, Tai Khoen and Tai Yuan.

         "sleeping woman mountain", is unusual land feature located in Mae Chan district on the western side of the highway between Chiang Rai and Mae Sai.[3] The silhouette of the mountain range takes the shape of a reclining woman when seen from certain angles. There is a viewpoint at Mae Chan, from where this land feature can be observed best.



Legend


         The main local legend on how this land feature came into being says that there was once a beautiful young lady in the area whose husband went away but failed to come back at the expected time. His wife became anxious and waited, but time passed and he wouldn't come. Suddenly the woman thought that her husband might be lost and went out of the house to search for him. She wandered anxiously for days through fields and forests all across the region, but couldn't find him. However, the lady didn't give up and walked and walked until she could walk no more.


         At that point the young lady was so exhausted she fell down on her back. Looking at the sky she cried bitterly, finally dying of despair. After her death the woman's ghost grew to a huge size and was covered by the surrounding earth, taking the shape of a sleeping lady with her face looking skywards.




Tourism


         There is a viewpoint at Amphoe Mae Chan (Mae Chan district), from where the "sleeping lady" can be observed best. Local tour guides like to joke that Doi Nang Non is "the highest mountain in the world", if the lady would get up and stand on her feet.


         There are a number of caves and water courses in these hills. Some of them have been developed as a tourist attraction.

Tum Luang is a cave inside the Doi Nang Non mountain massif with numerous stalactites and stalagmites. It is a very long cave with branches that go on for several kilometres.

Khun Naam Naang Non is a natural pond into which water flows from the rocks above. This water is said to be the tears of the lady's ghost.
