Rail: Delhi is connected to many Indian cities and towns by super-fast and express trains. The city's 3 main railway stations are New Delhi, Old Delhi and Nizamuddin. Luxury trains such as the Palace-on-Wheels, Fairy Queen and Royal Orient Express begin their tour from Delhi Cantonment railway station.
Road: Delhi is well connected to all the major cities of India by a network of highways and roads. There are three Inter State Bus Terminuses (ISBT), at Kashmere Gate, Sarai Kale Khan and Anand Vihar, as well as many starting points in and around the city, from which various state-managed and privately run transport facilities, operate.
Travel within Delhi:
You'll find a range of transport options within Delhi, from luxurious air-conditioned cars to the humble cycle rickshaw.
Tourist taxis ply interstate while the yellow and black taxis can be used to commute anywhere within the city and are relatively expensive but safe. Delhi Transport Corporation (DTC) buses go anywhere in the city and are the cheapest mode of transport. Auto rickshaws are another option, but remember to bargain for a reasonable fare. Luxurious special tourist buses can be arranged for traveling singly or alone. The recently introduced Metro underground railway line can be enjoyed as a joy ride.
Climate:
The summer months are not the ideal time to visit Delhi. It is hot, very dry and dusty. You can even get sunstroke unless you take precautions. Wear light cotton clothing. Try to keep your head covered. Cover your head and take your shoes off in places of worship. Stay away from beggars and touts. Female travelers are quite safe but the hazards of being a woman alone exist.
Best Time to Visit
The best time to visit Delhi is from August to March. Winters in Delhi are sunny and pleasant in the day, ideal weather for sightseeing.
