If you’re running late, don’t panic! The aquarium may still allow entry depending on capacity, but it’s always best to arrive on time to make the most of your visit.

While flexibility can depend on daily crowd levels, staff usually try to accommodate early arrivals when possible—especially during quieter hours.

Generally, the hours remain consistent throughout the year. However, on major public holidays or special occasions, they might tweak the schedule—so it’s always wise to check the latest updates online before heading out.
