An early 5:30 AM pickup for a sunrise boat ride along the Ganges — Varanasi is considered one of the oldest continuously inhabited cities in the world, and the ghats along the river have been the site of Hindu pilgrimage, cremation rites, and daily ritual bathing for thousands of years. The day continues with visits to the old city, Banaras Hindu University, and temples, closing with the evening Ganga Aarti prayer ceremony viewed by boat, before an overnight train to Agra. Tip: the sunrise boat ride is Varanasi's signature experience — dress warmly if traveling in winter months, since mornings on the river can be considerably colder than the city itself. The overnight train means packing an overnight bag separately from your main luggage for easier access.
