Phu Chi Fa, also Phu Chee Fah, is a mountain area and national forest park in Thailand. It is located at the northeastern end of the Phi Pan Nam Range, 12 km to the southwest of Doi Pha Tang at the eastern edge of Thoeng District, Chiang Rai Province. The cliff is part of an elevated area, the Doi Pha Mon sub-range, which rises near the border with Laos sloping towards the Mekong River. The highest point of the ridge is 1628 m high Doi Pha Mon. With views over the surrounding mountains, it is one of the famous tourist attractions of the Thai highlands near Chiang Rai. Tourists visit the mountain especially at dawn in order to catch a glimpse of the "sea of mist", the view of the fog-surrounded hills, with heights ranging between 1,200–1,600 m to the east of the mountain. The weather on Phu Chi Fa is cool, averaging around 20° C. It has three seasons: hot, rainy, and cool, influenced by the tropical monsoon.
