The Doi Tung royal villa, former residence of the Princess mother(mother of the present king) Somdej Phra Srinagarindra is also located high up on the hill. Thanks to Princess mother's interest and encouragement the hills were reforested. She was also instrumental in fighting against the opium trade, as a result the local hill tribes stopped growing poppies and began to grow other crops.
The royal Villa was originally built as a summer residence for the Princess Mother and now houses a museum and displaying her work to improve the life quality of local tribal people.
