Experience the richness of a forest that spans approximately 7,800 acres, teeming with diverse plant life including wildflowers and rare species such as the Chomphu Phuphan tree, Red Neem, Tan Color Orchids, and the Tarakian candle, along with over 100 species of wildlife. The local hill tribe, known as the Yao, refers to the highest peak in this range as "Finja Bao," meaning the dwelling place of angels and celestial beings. There are tales passed down through generations that every full moon on the 15th night, a breathtaking phenomenon occurs – a brilliant white light shining above the peak, creating a wondrous and mystical sight. Regardless of the legends, Phu Langka has become a sought-after destination for nature enthusiasts eager to conquer this summit at least once in their lifetime. This tourism site on Phu Langka offers sweeping views of the sea of fog, the only one of its kind in Phayao Province, from a summit that stands 1,700 meters above sea level. Visitors will be captivated by fields of blooming flowers, which typically bloom from July to December each year. Adventurers can trek through the rich ecosystem of the moist mountain forest and explore the headwaters along designated nature trails. Enjoy a variety of activities, such as conquering multiple peaks in the national park, including Phu Langka and Phu Num summits. Feel refreshed at the Phu Langka waterfall, admire the ancient million-year-old stone fields, and the enchanting limestone formations, as well as marvel at the ancient banyan forest. Additionally, delve into the past with traces of the Communist insurgents who once made their mark in Thailand's history. The national park also provides camping facilities and lodges for visitors.
