Doi Luang Chiang Dao is a limestone mountain in the Chiang Dao Wildlife Reserve area, Amphoe Chiang Dao.  This cone-shaped mountain is 2,195 metres from sea level, which makes it the third highest mountain in Thailand after Doi Inthanon and Doi Pha Hom Pok.  Narrow plains on top of the mountain overlook spectacular views that include a sea of fog on the Amphoe 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 highland flowers, birds, and butterflies.  Visiting Doi Chiang Dao needs an approval letter from the Director of Wildlife Reserve Division, Royal Forest Department.  Travel must be arranged at least 2 weeks in advance.
