From morning to noon:
The best tour plan for a Delhi one day sightseeing tour would be, to begin the tour by 8:30 am and first reach Qutub Minar. We suggest qutub Minar as its farthest tourist site in Delhi near Delhi Airport, and its best to come here in morning by 9 am.
Later from 10 am to noon, we suggest to visit Lotus temple and Humayun Tomb. Lotus temple is in South Delhi and quite close to Qutub Minar. Plus one can also visit Delhi’s 1st ISKCON Temple which is quite close to Lotus temple. Humayun Tomb is in central Delhi, and the its the Tomb of Humayun, father of Mughal emperor Akbar. Though do keep in mind that there is quite some walking here.
