This national park is centred on 2000m-high Doi Phu Kha, the province's highest peak, in Amphoe Pua and Amphoe Bo Kleua in northeastern Nan Province (about 75km from Nan). There are several Htin, Mien, Hmong and Thai Lü villages in the park and vicinity, as well as a couple of caves and waterfalls, and endless opportunities for forest walks. The park headquarters has a basic map and staff can arrange a local guide for walks or more extended excursions around the area, as well as rafting on the Nam Wa. The park is often cold in the cool season and especially wet in the wet season.
The park offers a variety of bungalows, and there is a nearby restaurant and basic shop.
