Weekdays: For the most peaceful experience, visit on weekday mornings, especially right after opening at 9am. The first projection show (around 9:30am) is usually the quietest, offering a nearly empty venue.

Weekends: Tend to be busier, especially during cultural events. Arriving just before opening (9am) gives you the best chance to skip long lines and enjoy the cistern in a calmer setting.
