The nearest airport is aurangabad and not bombay, ellora is 29 kms from auranagabad and ajanta is 120 kms away from aurangabad, wonderfull place but I suggest that both be given equal time by visiting ellora on one day and ajanta on one day.there are many buses from mumbai and other places.plus there are 2 direct trains from mumbaia and one direct train from delhi.there are two flights in a day to bombay and one to delhi.there are a host of 5 star hotels and three star too.a place worth visiting , in the month of december and jan.
