Best dark-sky sites near Bengaluru for stargazing and astrophotography

Bengaluru is Bortle 8-9 in the city core — useful for the moon, planets, and the brightest Messier objects only. The good news: within 3 hours of drive, you can reach Bortle 4 sites and the Milky Way comes back. Here is the practical list.

Skandagiri (≈ 70 km, 1.5h)

Bortle 4 at the base, 3-4 from the summit (if you trek up). North-facing horizon is clean. Light dome from Chikkaballapur on the east horizon — frame shots to the west. Best winter, when north humidity drops.

Nandi Hills (≈ 60 km, 1.5h)

Bortle 5 — closer than Skandagiri but more light bleed from Chikkaballapur + Devanahalli. Decent for visual under a moonless sky; deep-sky imaging is tougher without narrowband filters. Popular and crowded on weekends.

Coorg / Madikeri (≈ 250 km, 6h)

Bortle 3 on average, 2-3 from the higher coffee estates. The catch: monsoon (June-Sep) is fully overcast and post-monsoon (Oct-Nov) is unstable. December through February is the window. Pair with a homestay.

Hampi (≈ 340 km, 6.5h)

Bortle 3 within the ruins. Genuinely dark, especially north of Anegundi. The hidden cost: hot, dusty, and the seeing isn't as steady as the hill sites. Best November-February when the heat drops.

Hosur outskirts (≈ 50 km, 1.5h)

Bortle 5-6 at the city edge, drops to 4 if you push another 30 minutes south. Cheap, no booking needed, good for grab-and-go visual. Not dark enough for serious deep-sky.

Kemmangundi (≈ 270 km, 5.5h)

Bortle 3, high altitude (~1500m) which means lower atmospheric scatter. Western Ghats terrain — temperamental cloud cover even outside monsoon. Worth it when StarryPic's verdict for Kemmangundi shows Drive with high ensemble agreement.

When to actually go

December-February is the South Indian astro season. Skies stable, humidity low, monsoon long past. October-November is patchy. June-September is monsoon: stay home. April-May has clearest skies but punishing heat.
