In reply to SUColdo:
I've travelled fairly extensively in south India, but have only bouldered at Hampi. The other major climbing areas I'm aware of are:
Badami. Quite near Hampi but sandstone. Some sport, some trad, supposed to be very good.
Ramanagar. Granite domes and other formations, some quite impressive looking, visible from the main road between Bangalore and Mysore. When I was in the area, around 15 years ago, they had a reputation for extremely runout/minimalistic bolting, and I suspect given the climate rock quality wouldn't be up to Tuolumne standards, but if you like scary granite slabs the area would be worth exploring.
Western Ghats between Mumbai and Pune. Further north. Some big impressive-looking formations e.g the Duke's Nose (fa on aid Doug Scott a long time ago). I googled a bit prior to a business trip, but then as it turned out only had time for the hotel gym
Only of interest for locals, I suspect.
... so there's at least some names to start googling for
