The main attractions of the forest park are the "sea of fog" in the valleys in the early morning and the mountains of Doi Hua Ling, Doi Phu Lang Ka and Doi Phu Nom; the latter is a breast-shaped hill rising in an area of grassland.[1]
The vast pink fields of Dok Khlongkhleng (Melastoma malabathricum; Thai: โคลงเคลงขี้นก) are also one of the interesting sights of the park; other plants that are found in the area include Wightia speciosissima, Colquhounia elegans, Dendrobium heterocarpum, Impatiens mengtszeana and Paris polyphylla.[2] Formerly there had been opium cultivation in these mountains.[3]
Phu Langka Forest Park should not be confused with Phu Langka National Park (อุทยานแห่งชาติภูลังกา) in Nakhon Phanom Province.
