It is an ideal place for seeing the biodiversity of high elevation shola-grassland ecosystem. The park offers a magnificent view of the tea plantations and also of the rolling hills caressed by blankets of mist. The park becomes a hot destination when the hill slopes get covered in a carpet of blue, resulting from the flowering of Neelakurinji. It is a plant endemic to this part of the Western Ghats which blooms once in 12 years.
