Kosamphi Forest Park

Kosamphi Forest Park is a protected forest park in Hua Khwang Subdistrict, Kosum Phisai District, Maha Sarakham Province, northeastern Thailand, situated along the Chi River. Established as a forest park to conserve a remnant dry dipterocarp and mixed deciduous forest, it covers about 125 rai. The park is notable for its shaded woodland, riverside setting, troop of long-tailed macaques, and as a local recreation and nature study site near Kosum Phisai town.

Visitors can expect a small, shaded forest park with walking trails through dry dipterocarp and mixed deciduous woodland along the Chi River. The setting is quiet and natural with tall trees, riverside views, open pavilions and picnic areas. A resident troop of long-tailed macaques is commonly seen in the forest. There are simple nature trails, viewpoints toward the river, and areas for strolling, photography and relaxation. Facilities are basic and the park is primarily for nature observation and short walks.

Established on 1 October 1981 as Vanasathan (Forest Park) under the Royal Forest Department, now Department of National Parks, Wildlife and Plant Conservation, to protect a remaining tract of dry dipterocarp forest on the Chi River floodplain in Kosum Phisai District.

Serves as a community recreation and nature education site for Kosum Phisai and Maha Sarakham residents, known locally for its riverside forest and long-tailed macaque population that is part of the local natural heritage.
