Tamil Nadu’s First Dark Sky Park: Stargazing Magic Unveiled in Kolli Hills (Opened 27 February 2026)
A Gateway to the Cosmos: Tamil Nadu’s Newest Sanctuary for the Stars | Blog By Ravi Gopal
Imagine standing 1,350 meters above the plains on a clear February night in 2026. The cool mountain air carries the faint scent of wild jasmine and eucalyptus. As your eyes slowly adapt to the darkness over the next 20 minutes, the sky ignites into a breathtaking spectacle not just a few twinkling points, but thousands upon thousands of stars. The majestic Milky Way arches overhead like a glittering river of diamonds, the faint spiral arms of the Andromeda Galaxy become visible to the naked eye, and the glowing clouds of the Orion Nebula shimmer softly. This is not a faraway dream. This is the everyday reality at Tamil Nadu’s first Dark Sky Park, officially inaugurated on 27 February 2026 at the pristine Ariyur Shola Reserve Forest in Kolli Hills, Namakkal district.
Forest Minister R.S. Rajakannappan inaugurated the ₹1 crore project remotely from Chennai in the presence of Environment Secretary Supriya Sahu and senior forest officials. First announced in the Tamil Nadu Legislative Assembly on 25 June 2024, this landmark initiative transforms a protected shola forest into a dedicated sanctuary for stargazing, astrophotography, and environmental education complete with strict zero-light policies, solar-powered infrastructure, and three advanced telescopes.
In a country where more than 80% of the population can no longer see the Milky Way because of light pollution, Kolli Hills brings world-class, accessible dark-sky experiences to southern India. No need for expensive expeditions to the Himalayas or deserts. Whether you are a beginner family, a passionate photographer, a student group, or a solo traveller seeking peace, this park offers an intimate, magical connection with the universe right here in Tamil Nadu.
Why Kolli Hills Was Chosen: The Perfect Trifecta of Conditions
The Ariyur Shola Reserve Forest was selected only after rigorous scientific surveys measuring light propagation, atmospheric stability, and ecological sensitivity. The site delivers a rare “trifecta” that makes it ideal:
Natural Light Shield – Dense shola forests and surrounding ridges completely block skyglow from Salem, Namakkal, Trichy, and distant urban areas.
Altitude Advantage – Located at 1,350–1,450 metres, the park sits above the thickest layers of dust, haze, and turbulence, delivering sharper, steadier views of celestial objects.
Strict 1.5 km No-Light Zone – The core area enforces a total ban on artificial lighting, creating Bortle Class 3–4 skies — exceptional for southern India.
Beyond science, Kolli Hills is steeped in ancient Tamil culture. Known as “Kolli Malai” (Mountain of the Kolli Pavai), the hills feature in Sangam literature and legends of Lord Shiva’s cosmic dance. Siddhar sages meditated in its caves for centuries. The surrounding shola-grassland ecosystem is a biodiversity hotspot: over 200 bird species, 40+ butterfly species, the elusive Nilgiri marten, and the famous Neelakurinji flower that blooms once every 12 years.
Facilities & What You Can Experience at the Park
Three computer-guided telescopes (8-inch, 10-inch, and large equatorial mount) for effortless tracking of planets, clusters, and galaxies.
Guided stargazing sessions and overnight new-moon camps (organized 2–3 times every month).
Astrophotography workshops and daytime educational programmes for students on light pollution and celestial science.
Solar-powered operations, CCTV security, forest staff on duty, and a visitor interpretation centre.
Maximum 20 visitors per session to preserve serenity and darkness.
Staying Safe, Comfortable, and How to Reach Kolli Hills Dark Sky Park

Stargazing 101 for Beginners
Dark adaptation takes 15–20 minutes — avoid all white light (especially phone screens). Use only red-light torches. With the naked eye you can see up to 2,500+ stars, five to seven planets, and the Milky Way in glorious detail. Beginners can easily spot Jupiter’s moons and Saturn’s rings through the park telescopes.

Why Dark Sky Parks Matter in 2026
Protecting dark skies is essential for human health, wildlife, energy conservation, and cultural heritage. Light pollution disrupts sleep cycles, disorients migratory birds and sea turtles, wastes billions of rupees in energy, and severs our ancient connection with the cosmos.
