Elephants, tigers, wild dog, flying squirrel and lion-tailed macaque are found here. Vehicular traffic is allowed upto Mukkali from Mannarghat. From Mukkali one has to cover at least 24 km on foot to reach the source of river Kuntipuzha, which flows through the valley. Admission to the park is restricted.
Prior permission is required to visit the park.
