The park is one of the few remaining reliable habitats in Thailand for the wild green peafowl, an endangered species.
The name 'Doi Phu Nang' translates to 'Mountain of the Lady', derived from local folklore regarding the jagged peaks.
The limestone formations within the park create unique geological features, including small caves and steep cliffs.
The Tan Sawan waterfall features a distinctive multi-level drop that creates natural swimming pools at its base.
The park's elevation profile ranges from 200 meters at the valley floor to 1,202 meters at the summit.
Much of the park's vegetation is classified as dry dipterocarp forest, which undergoes a distinct color shift during the dry season.
Doi Phu Nang National Park is a protected area in the Chiang Muan District of Phayao province, primarily known for its rugged limestone mountain ranges and the notable Tan Sawan waterfall. The park supports a diverse ecosystem that serves as a natural habitat for green peafowl, which are frequently spotted in the wild. The landscape consists of mixed deciduous and dry dipterocarp forests covering approximately 850 square kilometers. Several tiered waterfalls, including Huai Kon and Tan Sawan, provide central focal points for visitors hiking through the forested trails. The terrain varies from low-lying valleys to peaks reaching up to 1,202 meters above sea level at Doi Phu Nang. It functions as a critical watershed area for the Yom River basin.
The mid-level viewing platform of the Tan Sawan waterfall provides the best vantage point for capturing the cascading water against the forest backdrop.
Bring insect repellent as the dense forest cover maintains high humidity levels throughout the year.
Carry sufficient water, as trail facilities are limited once you move away from the main visitor center.
Visit during the early morning hours to increase your chances of observing wild peafowl near the forest edges.
Do not attempt to hike the higher mountain trails without informing the park office, as paths can be poorly marked.
Parts of the park may close during the peak rainy season due to trail safety concerns; check with local forest authorities before planning a trip between July and September.
Maintain silence near wildlife viewing areas; wear sturdy, closed-toe footwear for uneven forest terrain; do not remove any natural materials like rocks or plants.
