The garden itself is nothing special, but the beauty of the Taj Mahal is definitely worth a visit. Tickets for foreign tourists are now 300 rupees (250 if you buy tickets online). Make sure you have enough time to arrive before sunset (around 4pm) so you can sit in the front row against the wall and take the best picture. You cannot enjoy the complete sunset, as the garden closes at five o'clock in the afternoon and the doormen will come and kick you out, and nonetheless, it is well worth it.
