It's one of those things that was simply a dream, but I am so excited and thankful that I will soon be traveling to India for a few short days on our way to Australia.
Delhi to Agra
There are various tour operators that run day trips and overnight trips to Agra, but you can safely travel alone by taking the Shatabdi Express or the Taj Express. The train is the most reliable and fastest way to get to Agra. Trains leave in the early morning from Delhi, arrive in Agra roughly two hours later, and return late in the evening. *It is crucial for foreigners, and especially for foreign female travellers, to buy an AC 3-tier ticket. That is the equivalent of a first-class ticket; it includes a full dinner. You can do all the major sites in Agra in one day, but consider an overnight trip that allows a more relaxing pace.
What time to visit
It's more worth your time to avoid the crowds and visit the Taj Mahal at sunrise. However, if you’re not a morning person, time your visit for sunset and stay as long as you can.
A 30-minute night-viewing ticket of the monument is available five days every month, but instead book a room at one of the several hotels with a view of the Taj Mahal all night long.
