Lam Nam Nan National Park, Thailand

Lam Nam Nan National Park covers an area of 999.15 square kilometres in Amphoe Mueang, Phrae and Amphoe Tha Pla and Amphoe Nam Pat, Uttaradit. The National Park gave birth to the main tributaries of the Mae Nam Yom in Phrae. It was declared as the Thailand's national park in 1998.

The Lam Nam Nan National Park features rugged mountain range higher than the highest level of water supply of Sirikit Irrigation. Most of the area consists of steep mountains with plains and is full of forest and wildlife.

Since Monsoon winds have an impact on Thailand's tropical climate, generally, the temperature is usually a little higher and more humid in daytime. Rainfall is more likely during the summer months of May through October and the average rainfall is 1,440 mm. per year. During the winter months, in the mountainous North, the temperature is cool enough for tourism.

Flora and fauna
Mixed deciduous forest, deciduous dipterocarp and dry evergreen forest dominate the National Park including Tectona grandis, Afzelia xylocarpa, Xylia xylocarpa, Dalbergia oliveri, Pterocarpus macrocarpus and Shorea obtusa.
