All major cities have numerous Internet cafes for email and general surfing. For security purposes, you will have to produce an I.D. to surf.
Please take particular care when attending a religious place (such as a temple). Dress and behave appropriately – don’t wear shorts and sleeveless tops (this applies to men, too), and do not smoke or hold hands. Shoes and western head ware must also be removed. No carvings or statues of deities must be touched within the temple or religious place. Photography is prohibited in certain sections of sacred sites. Please ask your local guide or tour leader for further information if you are in doubt. Please also be aware that some temples may have off-limit sections that prevent tourist entry.
All major international airports in India, including Delhi, Mumbai, Bangalore, etc., have exchange counters at their terminals.
The best time to explore India is between October and March.
It is quite an issue for women. The best option is to stay fairly covered. Baring a lot of skin is unwelcome in smaller towns, and men would ogle at you, whereas, in bigger towns like Delhi and Mumbai and beach areas like Goa, people are comfortable. Especially when going to religious or historical sites, be mindful of what you wear to avoid offending anyone.
