This national park is centred on 2000m-high Doi Phu Kha, the province’s highest peak, in Amphoe Pua and Amphoe Bo Kleua, about 75km northeast of 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 is often cold in the cool season and especially wet in the wet season.

Park HQ has a basic map and staff can arrange a local guide for walks or more extended excursions around the area, plus rafting on Nam Wa.

The park offers a variety of bungalows (two to seven people 300B to 2000B), and there is a nearby restaurant and basic shop.

To reach the national park by public transport you must first take a bus or sŏrng·tăa·ou (passenger pick-up truck) to Pua (50B, two hours, hourly from 7am to 5pm). Get off at the 7-Eleven then cross the highway to board one of the three daily sŏrng·tăa·ou (50B, 30 minutes) that depart at 7.30am, 9.30am and 11.30am.
