this is the highest peak in the area (and the third-highest in all of Thailand after Doi Inthanon and Doi Pha Hom Pok). It is a limestone mountain in the Chiang Dao Wildlife Reserve area. Narrow plains on top of the mountain overlook spectacular views that include a sea of fog on the Chiang Dao side, Doi Sam Phi Nong, the Chiang Dao mountain range, and the far end of Doi Inthanon. The peak is cool and windy. It is full of rare flowers, birds, and butterflies
