Doi Suan Ya Luang was originally an opium-growing area on the hills of the Mien (Yao) hill tribe in San Charoen Village, Tha Wang Pha District, about 77 kilometers from Nan City, but at present, it becomes another famous coffee plantation area. Tourists will not only be able to see the atmosphere of the coffee plantation on the mountain range but also experience the simple way of life without electricity. Only the moonlight and the stars in the night sky are friends. Furthermore, traveling from San Charoen Village up to Suan Ya Luang must be a 4WD vehicle only, with a one-day cost of 1,300 baht and an overnight stay at 1,600 baht for ten people. For those who love a tent, you can bring a tent up and spread it on the mountain.
