It has mountainous topography with elevation varying from 200 m – 1761 m. The area emerged from "uplifting and exposure of the underlying sedimentary (Indosinias schist-clay-sandstone) complex". Sandstones are also seen spread in layers. Extensive flat uplands with sandstones with hardly any soil cover are also part of the topography of the park.

The park has monsoonal climate with recorded annual rainfall of 1,936.1 mm (with higher reaches recording more rainfall). The mean annual temperature is 26.6 °C with recorded the mean maximum of 31.6 °C and the mean minimum temperature of 21.5 °C.

The forests are evergreen, Shorea mixed deciduous forest, dry dipterocarp and pine type; particularly coniferous forest, of monospecific stands of Pinus latteri, Fokienia hodgsinsii, bamboo, and fire-climax grasslands.

Animals found in the park include elephants, tigers, bears, 13 pairs of white-cheeked gibbons, langurs, reptiles, amphibians and birds. Sightings of the green peafowl have been reported near Ban Nakhay and Ban Nakhan Thoung, although it was generally once considered extinct in Laos. Conservation management has increased its population.
