Rough Guide to India
Shouldn’t be a problem to pick up the new India guide from your local bookshop before you leave as it should be in stock by then, but I’m afraid we can’t guarantee. Good luck and please write back with any Delhi tips/highlights after your trip!
If you don’t quite get the new guide the last RG India is excellent, and can easily be supplemented with up to date info from the internet, TA, or forums such as this one. Have a look here to get you started
