The Pambar River, which feeds the falls, is one of the few rivers in Kerala that flows eastward, eventually joining the Amaravathi River in Tamil Nadu.
The trekking route to the waterfall is a habitat for the grizzled giant squirrel, which is endemic to South India.
The falls are situated within the Chinnar Wildlife Sanctuary, which contains the only dry deciduous forest in Kerala due to its location in the rain shadow region of the Western Ghats.
The site features ancient dolmens and rock paintings nearby, indicating historical human habitation in the surrounding Marayoor region.
Thoovanam Waterfalls is a significant cascade located within the protected area of the Chinnar Wildlife Sanctuary in the Idukki district of Kerala. The waterfall is formed by the Pambar River, which flows through the sanctuary’s dry deciduous forest landscape. Access requires a guided trek through forest trails monitored by the Kerala Forest Department to ensure environmental protection. The falls are known for their proximity to natural habitats of endangered species, including the grizzled giant squirrel. The water drops over a series of rocky tiers, creating a series of natural pools at the base. The site is remote and lacks developed tourist infrastructure, preserving the natural state of the riverine ecosystem.
From the rocky outcrops directly facing the main plunge of the waterfall.
Hire a mandatory forest guide at the sanctuary entry gate to ensure safety and navigation on forest trails.
Carry sufficient water and snacks, as there are no food or beverage outlets near the waterfall.
Wear sturdy, closed-toe hiking shoes with good grip due to the uneven and often slippery terrain along the riverbank.
Attempting the trek without a designated forest guide or during heavy rainfall when trails become hazardous.
Trekking activities may be suspended during extreme monsoon weather or high forest fire risk periods; verify with the forest office before arrival.
Do not litter, carry back all plastics, and maintain silence to avoid disturbing local wildlife.
