Because of the weather and the average temperature, I suggest you move around on a cloudy day or in the evenings. Nonetheless, travelling is not difficult. if you have your own conveyance, nothing like it. Otherwise, there are three options: Cab services, autorickshaw and bus.
However, A.P. Tourism conducts day trips to many locations around Hyderabad. These are city tours covering major places of interest, Ramoji Film City tour, Golconda fort tour and one specially for Husain Sagar(whole day). You can find details on the web page http://www.tourisminap.com/hyderabadtours.htm.
Let's explore the options:
City Cab: I still have to find more details on this but you have many cab services available.
Autorickshaw: Suggested if you want to travel on your own but do not want to travel in the bus. Always prefer travelling on meter, not on fixed rate. But do remember, 90% of them have tampered meters, so you end up paying different amounts for same distance at different times. For example, twice I travelled from Punjagutta to Lumbini Park and the amounts were Rs 27 and Rs. 32 resp. So watch out for such cases.
Bus: The bus services are satisfactory and frequent from one place to another. However, there are areas, where there are no direct buses. So you may have to change one or two buses before reaching your destination.
Best way to see the city is to get a rental bike/car and take your vehicle to anywhere where you want to have a look in side outside of the city.
Major downside of this way is that traffic sense is horrible in hyderabad and if you are not aware of the local traffic sense of driving you might end up injuring urself.
Another best in this case will be the tuk tuk rides.You can bargain them and tkae them anywhere in this city
Auto rickshaw (or just call "auto" for short) is one of the most convenient transportations ones can get in India. In Hyderabad, minimal fare for auto rickshaw is Rs10. If the auto is on meter, Rs25 can really bring you very long distance. But most auto drivers will not use meter, some even remove the meter so that you have no choice but to use their service at the negotiated price.
I even have quarrel with one auto rickshaw guy driving till meter hit more than Rs18 from Women College entrance to one of those restaurants slightly across the bridge towards the Charminar direction. Wasting my time!!
Traffic in Hyderabad is really something, I wouldn't recommend you to drive, the best thing would be much to choose some kind of transportation, including cars which are driven by locals.
There's really big confusion and everything is very hectic.
There are many motorbikes (VESPAs) and trucks, which are painted in yellow, green and they give a dose of joy to traffic:)
Air Deccan, the country's first low cost regional service gets underway, with prices up to 50 per cent less than conventional rates. Air Deccan has flights to all major towns in Karnataka, Tamil Nadu and Andhra Pradesh.
Return flights on the same day will result in huge cost savings by business passengers. The reporting time being 45-minutes before time of departure, the baggage limit per passenger is 15 kg. That makes interstate airtravel very cheap and definetely affordable.
Book u r tickets simply via a phone call or the Internet, take off from the tarmac is assured within 15-20 minutes from the time of departure.
City Cabs the new cab service for hyderabadi's. Well not new though, it has been around for a few years, its just that they have expanded thier network and have become quite cheaper now. The cabs now come with meters, steroes, and a pleasant 24 hours service. Starting at a minimum fare of 40 rupees, they work out quite comfortable and affordable when ur moving in a group. Ya waiting charges are Re. 1 after 10 mins. Pack luggage upto 60 kgs.
Buses are the cheapest transportation and they operate two types of bus services- the ordinary road transport corporation (RTC) buses and the metro liners. The former tends to be a bit crowded and the latter are more comfortable and don't operate on all routes.
Auto Rickshaws are certainly the most popular mode of transport within the city, both a bane and boon...seriously. Though totally safe to travel in, having clear cut directions in advance helps.
Pre-paid taxis are available from the Airport as well as the Railway station. Hire 'City Cabs', and they will take you to any corner of the city. The fares depend on the distance.
If you are just coming to Hyderabad, then it is worth taking a flight. Since this is rarely the case, you can take buses/ trains to the city. There are overnight buses from Bangalore and buses from Mumbai/ Goa & Madras
Auto Rickshaws as usual!!!
from delhi, you can either take a 2 hour long flight (indian airlines/jet airways) or catch a train-- the rajdhani express gets you there in 22 hrs (meals included + airconditioned) or take the AP express, which takes a little longer- 25 hours.
auto rickshaws and taxis are the best way to get around. alternately, you could ask your hotel to arrange a taxi for you.
Get on an Yellow Auto Rickshaw, Please insist on using the meter. occasionally you would get Auto's without meter. Just flag down another. There is plenty around.
