Hanle Dark Sky Reserve

Hanle is home to one of the world's highest astronomical observatories at 4,500 m — the Indian Astronomical Observatory (IAO) run by the Indian Institute of Astrophysics. Located in the remote Changthang plateau near the India-China border, Hanle is also one of India's premier dark sky destinations and a top stargazing location in Ladakh. Requires Inner Line Permit. The stark high-altitude landscape with virtually zero light pollution makes it ideal for astrophotography.
