Monkey Falls
"The 18-Meter Natural Cascade & Gateway to the Anamalai Hills"
Monkey Falls is a popular 18-meter (60 feet) natural stepped rock waterfall situated along the Pollachi–Valparai Ghat Road (State Highway 78) near Aliyar Dam at the base of the Anamalai Tiger Reserve in Coimbatore District, Tamil Nadu. Located 29 km from Pollachi and 65 km below Valparai, Monkey Falls serves as the iconic road trip gateway to the 40 hairpin bends mountain pass.
1. Overview, Topography & Identity
Tumbling over smooth, dark charnockite rock terraces in the rugged foothills of the Anamalai mountain range, Monkey Falls is one of the most accessible and refreshing natural water stops in western Tamil Nadu. Situated along State Highway 78 just 5 kilometers past Aliyar Dam in Coimbatore district, the cataract drops 18 vertical meters (60 feet) into a wide, clear shallow pool.
The Pristine Foothills of the Anamalais
The approach to Monkey Falls leads through coconut palm groves and dry deciduous scrub before climbing into the dense moist deciduous forest buffer of the Anamalai Tiger Reserve. The crystal-clear mountain water, rushing over natural stone ledges beneath the shade of tropical trees, provides a welcoming mountain respite for travelers embarking on the steep drive to Valparai.
Pollachi Coconut Capital & Agroforestry Corridor
The plains surrounding Pollachi are internationally acclaimed as the **Coconut Capital of Tamil Nadu**, producing premium GI-tagged tender coconuts, coir fiber products, and organic jaggery. The transitional highway corridor between Pollachi and Monkey Falls features endless green canopies of coconut palms, bordered by traditional water canals fed by the Aliyar River basin.
Fed by an unpolluted mountain stream descending from the high grass ridges of the Anamalai hills, the waterfall drains into the Aliyar River basin, feeding the downstream reservoir before flowing into the Bharathapuzha river system.

2. Geology: Anamalai Charnockites & Aliyar Catchment
The bedrock of Monkey Falls belongs to the Southern Granulite Terrain of the Western Ghats, formed of massive Neoarchaean charnockites and granitic gneisses dating back over 2.5 billion years.
Stepped Rock Terrace Hydrodynamics
The mountain stream encounters a natural fault break in the rocky foothills. Over millennia, the high-velocity flow has smoothed the hard charnockite bedrock into a series of rounded, undulating terraces. The water fans out into multiple cascading white ribbons before crashing into a shallow, gravel-bottomed pool bordered by protective stone embankments.
3. The 40 Hairpin Bends Valparai Ghat Road Gateway
Monkey Falls is the iconic starting landmark for one of South India's greatest mountain engineering drives:
The 40 Hairpin Bends Highway (SH 78)
Immediately past Monkey Falls, State Highway 78 begins its dramatic ascent up the northern face of the Anamalai range through **40 numbered hairpin bends** engineered across 40 kilometers of steep mountain terrain. Travelers pause at Monkey Falls to stretch their legs and cool down before tackling the exhilarating climb to the high-altitude tea plantations of Valparai (1,193m MSL).
Carver Marsh & The Father of Anamalais Heritage
The historic road winding past Monkey Falls owes its origin to pioneer planter **C.R.T. 'Carver' Marsh**, known as the 'Father of the Anamalais'. In the 1890s, Marsh explored the untamed rainforest plateaus above the falls, introducing high-altitude tea and coffee cultivation. Today, his memorial statue stands overlooking the tea estates at Kavarkal on the upper reaches of the ghat road.

4. Anamalai Tiger Reserve Ecology & Bonnet Macaque Fauna
The waterfall is sheltered within the rich biodiversity of the Anamalai Tiger Reserve buffer:
Bonnet Macaque Troops & Forest Wildlife
The waterfall derives its popular name from the large, habituated troops of native **Bonnet Macaques (*Macaca radiata*)** that inhabit the rock overhangs and tree branches. The surrounding forest canopy also hosts the Malabar Giant Squirrel, Indian Spotted Chevrotain, Asian elephant herds moving across the Aliyar corridor, and over 150 species of forest birds including the Indian Pitta and Emerald Dove.
Conservation biologists frequently monitor the higher canopy of the Anamalais above the falls, where small troops of the endangered **Lion-tailed Macaque (*Macaca silenus*)** and the elusive Nilgiri marten (*Martes gwatkinsii*) inhabit undisturbed evergreen shola pockets.

| November – January (Northeast Monsoon & Winter) | Clean, steady crystal-clear cascading stream | Pleasant sunny weather (20°C–28°C) | Best overall window for families & road trips |
| February – March (Late Winter) | Moderate, steady cascade; shallow pool | Warm days; clear mountain roads | Optimal for Valparai hill station weekend getaways |
| April – June (Summer) | Slender stream; exposed rock terraces | Warm days (30°C–36°C); cooling pool splash | Popular summer weekend halt from Coimbatore |
