The Taj Mahal is one of the 7 Wonders of the World, and for good reason; it is absolutely exquisite! This marble mausoleum was built by the Emperor Shah Jahan as a memorial to his favorite wife.
We arrived in Agra in the afternoon and visited the Red Fort and Baby Taj. In the morning we woke up to visit the Taj Mahal at 6:00 AM to get there for sunrise, and it was stunning. The day we went was a little rainy (with tons of mosquitoes), but it did not detract from the beauty and wonder of the magnificent building and its surroundings. It's easy to spend a few hours walking the grounds, exploring the Taj, and taking tons of pictures!
I will advise that while Agra may not be the most popular city in India, you really shouldn't miss the Taj Mahal, and should try to at least see the landmark, even if you do not stay in the city for longer than a day.
