Berijam Lake Travel Guide

Origins & Colonial Hydrology: The Pristine Catchment of 1867

Hidden 21 kilometres southwest of Kodaikanal within the deeply folded, mist-shrouded valleys of the upper Palani Hills, Berijam Lake is a magnificent 24-hectare freshwater reservoir resting at an elevation of 2,165 metres above sea level. Unlike Kodaikanal Lake, which is encircled by urban hotels and tourist bazaars, Berijam Lake remains completely untouched by commercial construction, surrounded by an amphitheater of dense shola cloud forests, montane grasslands, and towering pine ridges.

The lake has a fascinating hydrological history. Originally a natural marshy valley known as the "Fort Hamilton" site, the reservoir was engineered in 1867 by Colonel Douglas Hamilton of the British Army, who surveyed the plateau for military sanatoriums. In 1912, the colonial government constructed a masonry dam across the outflowing stream to create a protected reservoir, with water piped via subterranean aqueducts to provide unpolluted drinking water for the downstream agricultural township of Periyakulam in the plains.

In 2013, the surrounding wilderness was officially notified as part of the *Kodaikanal Wildlife Sanctuary*, establishing stringent ecological protections that halted all commercial resort construction, restricted vehicular traffic, and preserved the lake basin as an inviolate biological sanctuary.

The Enchanted Forest Drive: Moir Point, Silent Valley & Caps Fly

The journey to Berijam Lake along the restricted *Berijam Forest Road* is one of the most scenic wilderness drives in India. Passing through the Forest Department checkpost at *Moir Point* (named after Sir Thomas Moir, who initiated the road in 1929), vehicles enter a protected realm of moss-draped cypress, eucalyptus, and wattle groves.

The first scenic stop along the route is *Silent Valley View*. Perched high above a precipitous gorge, the viewpoint looks down upon an astonishingly deep, untouched valley enveloped in velvet green rainforest canopy. The silence here is profound, with swirling morning mists creating dramatic visual chiaroscuro as clouds rise from the plains.

Further along sits the curious geological phenomenon known as *Caps Fly Valley* (or the Boomerang Viewpoint). Due to extraordinary aerodynamic wind shear created by the convergence of mountain ridges, any light object thrown over the cliff edge—such as a cloth cap, cardboard cup, or dry leaves—is instantly caught by powerful ascending air currents and propelled right back up into the thrower’s hands.

The Lake Basin: Crystal Waters & Shola Ecology

Arriving at the lake basin, visitors step into an extraordinarily peaceful landscape. The waters of Berijam Lake are crystal clear, reflecting the dark emerald shadows of the surrounding shola trees and the azure sky above. The shoreline is bordered by reeds, white water lilies, and native sedges that filter rainfall before it enters the reservoir.

The forest surrounding the lake is home to ancient shola trees including *Syzygium*, *Litsea*, and *Rhododendron arboreum nilagiricum*, whose bright scarlet blossoms illuminate the mountain canopy between January and April. The forest understorey is famous for its diversity of rare medicinal plants, including *Hypericum mysorense* (St. John’s wort) and *Gaultheria fragrantissima* (wintergreen oil plant).

A modest forest rest house, constructed during the British colonial era with timber gables and stone chimneys, sits on a grassy knoll overlooking the lake. The grounds feature a small botanical medicinal garden maintained by the Forest Department, showcasing indigenous herbal species used in traditional Siddha and Ayurvedic medicine.

Wildlife Sanctuary Haven: Gaurs, Elephants & Nilgiri Tahr

Because civilian human access is strictly regulated and nighttime presence is prohibited, Berijam Lake functions as an active wildlife haven. The open montane grasslands surrounding the water are favored grazing grounds for large herds of *Indian gaur* (the magnificent wild bison of South India), whose muscular dark frames can frequently be seen grazing peacefully on the reed banks in the early morning.

The lake also lies along an ancient migratory corridor utilized by wild Asian elephant herds moving across the high plateau between the Chinnar Wildlife Sanctuary in Kerala and the Palani hills forests in Tamil Nadu. Fresh elephant foot tracks and crushed vegetation along the water’s edge are common sights for visitors.

Other wildlife inhabiting the sanctuary includes the leopard, the dhole (wild dog), the sambar deer, the barking deer (muntjac), the wild boar, and on the higher crags near Mathikettan Shola, small populations of the endangered *Nilgiri tahr*. Birdwatchers can spot rare highland endemics including the Nilgiri wood pigeon, the Nilgiri flycatcher, the White-bellied shortwing, the Pied bushchat, and migratory crested serpent eagles.

The Drinking Water Lifeline & Zero-Plastic Conservation

The uncompromising ecological protection of Berijam Lake is rooted in its role as a vital municipal lifeline. The reservoir provides pure, untreated drinking water to over 100,000 residents in the municipal towns of the plains below. Any chemical contamination, petroleum spillage, or plastic litter would pose an immediate public health emergency.

Consequently, the Tamil Nadu Forest Department enforces strict conservation regulations: all single-use plastics are prohibited, vehicles must maintain low speeds (20 km/h) to avoid disturbing wildlife, and visitors are required to stay strictly within designated perimeter viewing zones. Walking to the water’s edge or discarding food waste is strictly penalized.

These conservation efforts have successfully preserved Berijam as one of the cleanest, least disturbed freshwater ecosystems in the Western Ghats, demonstrating how strategic eco-tourism regulations can harmonize public access with water security and wildlife protection.

Permit Logistics, Visiting Windows & Travel Planning

A visit to Berijam Lake is conducted as a four- to five-hour half-day excursion originating from Kodaikanal town. To undertake the trip, travelers must first obtain an official Forest Entry Permit from the District Forest Office (DFO) in Kodaikanal (located on Club Road, open from 08:30 to 10:00). Due to the daily cap of 80 to 100 vehicles, obtaining permits during peak holiday seasons (April–May and long weekends) requires queuing up early by 07:30.

Alternatively, travelers without private vehicles can book a tour through the Tamil Nadu Forest Department’s authorized safari mini-buses, which depart from the forestry reception center daily, providing an informative, hassle-free eco-guided tour through the sanctuary.

The sanctuary gate at Moir Point opens for permitted vehicles at 09:30, and all vehicles must exit the forest checkpost before 15:00. There are no food stalls or commercial shops inside the sanctuary; visitors should carry their own packed food and reusable water bottles from Kodaikanal, ensuring that all trash is carried back out.
