Grass Hills National Park

Grass Hills National Park is a protected shola-grassland tract within the Anamalai Tiger Reserve near Valparai in Coimbatore District, Tamil Nadu. Located in the Western Ghats, it covers rolling montane grasslands interspersed with evergreen shola forests. Noted for high biodiversity, endemic flora and fauna, and pristine wilderness, access is strictly regulated by the Tamil Nadu Forest Department and allowed only with prior permission and guide.

Visitors can expect a pristine, restricted-access wilderness of undulating montane grasslands and patches of shola forest in the Western Ghats. Entry is only with prior permission from the Tamil Nadu Forest Department and a mandatory forest guide. The experience involves a guided trek of several kilometres through open grasslands and forest patches with opportunities to see endemic plants, birds, Nilgiri tahr and other wildlife. There are no tourist facilities inside; the landscape is undeveloped and tranquil.

Grass Hills forms part of the Indira Gandhi Wildlife Sanctuary notified in 1976, with the Grass Hills area notified as a National Park in 1989. It was later included as a core area of the Anamalai Tiger Reserve. The shola-grassland landscape represents an ancient, ecologically significant ecosystem of the Western Ghats conserved for its biodiversity.
