Central Zone (King Kothi, Abids, Lakdikapul, Mehdipatnam, Tolichowki, Banjara Hills, Jubilee Hills, Ameerpet, Pujagutta, Himayat Nagar, Kacheguda, Narayanguda, Chikkadpally and Nallakunta.) The center of Hyderabad has upscale neighborhoods along with venues of entertainment and dining. There is lots to see and do.
South Zone (Charminar, Patthargatti, Afzalgunj, Shalibanda, Falaknuma, Dabirpura, Yakutpura and Purani Haveli.) This is where most of Hyderabad's famous historical sights are. Also called Old City or Purana Shahr, this is home to Hyderabad's most lively and authentic shopping experience. The Taj Falaknuma, once a palace, now a luxury hotel, is located here.
North Zone (Begumpet,Secunderabad, Malkajgiri, Trimulghery, Alwal and Kundanbagh.) The North Zone was the site of the former British military installation in Secunderabad. Completely different from the South Zone, this zone is far more cleaner and well planned than the South.
West Zone (Kukkatpally, Miyapur, Bharat Nagar, Gacchibowli, Nanakramguda and HITEC City.) This is home to Hyderabad biodiversity development. Many of Hyderabad's business travelers stay in this area.
East Zone (Uppal, Kapra, Dilsukhnagar, LB Nagar, Gaddiannaram and Saroornagar.) Home to many educational institutes.
Because most travel to Hyderabad involves business, many never see the 400-year-old Hyderabad. The image that one immediately observes is of a sprawling metropolis featuring office buildings and shopping malls with glass facades. The whole of the city seems to be under construction or renovation. The "old city" that was once the seat of the Nizam, the ruler of the largest and the most opulent "princely state" and its twin city of Secunderabad can be seen only if one makes the effort.
Hyderabad is known by many names, including the City of Pearls, the City of Nawabs, the Biryani City and, because of its concentration of high-tech corporate offices, Cyberabad.
