Good Time
Hanle in June
Ladakh, India
June is the first reliable month for reaching Hanle. The road from Leh via Nyoma is open, Inner Line Permits are being processed in Leh (1-2 days), and the weather is manageable at 5-20°C. The observatory is visible from the village — a white dome on a 4500m ridge that looks like it belongs on another planet. The Changthang plateau is brown turning green, with marmots emerging from burrows and black-necked cranes arriving at the wetlands near Tso Kar. The night sky in June is Hanle's core product: the Milky Way is visible to the naked eye with a clarity that makes city people weep. Bring your own telescope or binoculars.
The June story
The observatory sits on a 4500m ridge above the village — the 30-minute walk up is breathtaking in both senses. Daytime, the dome is closed and the site quiet. Contact IIA Bangalore's public outreach office at least 6 weeks ahead for tour possibilities — they occasionally accommodate small groups. Even without entering, the setting is extraordinary: a modern telescope dome surrounded by 360 degrees of Changthang plateau, the curvature of the earth almost perceptible at the horizon. The Hanle Monastery below has original 17th-century murals that rival Alchi and Tabo in quality — fewer tourists have seen them than almost any comparable artwork in Ladakh. For stargazing, set up after 9 PM: the Milky Way core is visible from June onwards, and with a basic DSLR (ISO 3200, f/2.8, 20-second exposure) you can capture images that look professionally processed. Homestay meals: breakfast chai with tsampa, lunch and dinner of dal-rice-sabzi, ₹1500-2500 per night all-inclusive. The nearest anything — shop, fuel, hospital — is Nyoma, 100 km east.
