You can visit any day of the week from 9 am to 6 pm Monday through Friday and from 9:30 am to 5 pm on Saturdays and Sundays. The best time to visit, however, will depend on what you hope to experience. If you want to avoid crowds, consider visiting during off-peak hours or on weekdays. For those seeking an unforgettable experience, visit during special events such as New Year's Eve when visitors can enjoy spectacular fireworks displays from atop this impressive building.
