One day
Start before dawn at the Taj Mahal as the gates open, and give it a slow hour or two in the morning light. Mid-morning, cross to the Agra Fort for the Mughal palaces and the emperor's tower with its view back to the Taj, then break for a Mughlai lunch and some petha in the old city. In the late afternoon, cross the river to Mehtab Bagh for the sunset reflection, or visit the delicate Baby Taj on the way.
