The elevation drop from peak to valley creates significant temperature variations, sometimes reaching near-freezing levels at high altitudes during winter.
Doi Phu Kha National Park covers 1,704 square kilometers of the Luang Prabang Range in Nan Province, Thailand. It is home to the rare Chomphu Phu Kha (Bretschneidera sinensis), a prehistoric tree species found nowhere else in Thailand. The park features a rugged limestone landscape with high mountain peaks including Doi Phu Kha, the highest point in Nan at 1,980 meters. The area acts as a watershed for the Nan River, feeding various tributaries through deep valleys. Several waterfalls, such as Ton Tong and Huai Kon, are accessible via established forest trails. The park encompasses diverse ecosystems ranging from tropical rainforests to deciduous forests and high-altitude grasslands. It is a critical habitat for endangered wildlife, including the Malayan sun bear and the Asiatic black bear. The park also preserves the cultural history of the local Hmong and Mien hill tribe communities residing in the vicinity. The geography is characterized by deep canyons and karst cliffs, creating distinct microclimates across the altitude range.
