How to Get There

The Indian Astronomical Observatory (IAO) is located in Hanle village, about 255 km from Leh, via Karu – Chumathang – Nyoma – Loma – Hanle. The drive takes 7–8 hours, and the route is motorable during the warmer months.

• Indian tourists need an Inner Line Permit (ILP).

• Foreign tourists need a Protected Area Permit (PAP), applied through a registered agent.

Both Indian and foreign travelers can stay overnight in Hanle and visit the observatory area with proper permits.

What to Expect

Perched at 4,500 m, this is one of the highest observatories in the world, operated by the Indian Institute of Astrophysics. Though the core facility is closed to the public, the surroundings are accessible and perfect for unfiltered night skies and clear views of the Milky Way. You won’t find city lights or noise—just silence, stars, and space.

For the Curious

• Home to the Himalayan Chandra Telescope, remotely operated from Bengaluru.

• Site was chosen for its high altitude, dry air, and zero light pollution.

• Hanle has become a hotspot for amateur astronomers and astro-photographers.

• You can’t go inside the observatory, but the sky itself is the main event.
