Tamil Nadu Launches First Dark Sky Park in Kolli Hills

Tamil Nadu has inaugurated its first Dark Sky Park at the Ariyur Shola Reserve Forest in Kolli Hills, Namakkal district, marking a significant step towards promoting astro-tourism in the State. The facility was launched by Forest Minister R. S. Rajakannappan from Chennai. The initiative positions the State as an emerging destination for night-sky observation and scientific tourism.

Located in an ecologically sensitive forest landscape, the park offers clear views of celestial bodies including stars, planets, the Milky Way galaxy and the moon. The site was selected after detailed ecological and sky visibility assessments.

Strategic Location and Infrastructure

Kolli Hills was identified as an ideal site due to its elevated terrain, dense forest cover and minimal urban light pollution. Nearly a 1.5 km radius around the park remains free from artificial light, ensuring optimal dark-sky conditions. The higher altitude and natural terrain further reduce external light interference.

Established at a cost of ₹1 crore, the park is equipped with three advanced telescopes and solar-powered infrastructure to ensure sustainable operations. The centre will function both at night for stargazing and during the day to promote scientific literacy among students, researchers and visitors.

Operational Plan and Visitor Management

The park will operate primarily from January 15 to June 15, when skies remain clear for nearly six months annually. It will remain closed during the monsoon season. Structured stargazing sessions and whole-night observation camps will be organised two to three times a month, particularly during the new moon phase for enhanced visibility.

The Forest Department has partnered with Trek Tamil Nadu, which has signed a memorandum of understanding with Starvoirs to conduct astronomical events and overnight programmes. Accommodation will be available at Agaya Gangai eco-huts, with transport arrangements facilitated by the department.

Safety Measures and Sustainable Tourism

Robust safety arrangements have been implemented at the site. A watchtower has been constructed approximately 20 metres from the park, with a frontline forest staff member stationed during night hours. CCTV cameras have been installed for continuous monitoring. Two Eco-Development Committee members will assist in visitor facilitation and operational management.

Important Facts for Exams

Blending Conservation with Astro-Tourism

The initiative reflects Tamil Nadu’s broader approach to combine conservation, environmental stewardship and responsible tourism. By integrating regulated visitor access, scientific education and livelihood opportunities for local communities, the Dark Sky Park model seeks to create a sustainable framework for nature-based tourism while preserving fragile forest ecosystems.
