Too much noise? Too many people? Find the bridge between Charminar and North Hyderabad and take the small path down to the river, where you can take a stroll. Make sure not to go alone. We were two students and were told by police that it can be an unsafe route.

 
However, it is a somewhat refreshing (despite the low water quality) way to experience the city. The river is what made the city possible, now she just lies in between major sights, being neglected and overseen. From here, you have a good view of the Osmania General Hospital and the Hyderabad High Court, you might also see some animals... When you walk to the west, you can go up and see one of the older colleges of the city, a pretty old red building.
