There are a large number of buses reaching out to even the most remote areas. They start early at 4 am and ply till almost midnight. Auto rickshaws are the best mode of transport, though getting one in a residential area late at night is difficult. They do not ply by the meter unless you take them to task. After 10 pm, autos charge 50 per cent over the meter and may charge extra to go to far away places. If invited for dinner, it would be a good idea to get a lift back. If hiring an auto for a round trip, fix the fare in advance and be explicit in your instructions to the auto driver regarding the time of your pick up and so on. For the well heeled, there are AC and non-AC cabs. There are several cab companies offering round the clock service. You need to fix the fare before you set out on your journey. There are however standard rates, usually charged per kilometer. The ferry service operates from 0800 - 1700 between the Harbour and Yarada hills. It is advisable to take one to visit the Dolphin Lighthouse.
