No, there is no timed entry. Doors open at 5 p.m. Last entry to the event is 8 p.m., and the event concludes at 8:30 p.m.
 

Parking is available on the North and South Lots.

While parking for the event is free, lots are filled on a first-come, first-served basis and may reach capacity. If lots are full, limited street parking within the boundaries of Forest Park also is available for free.

Prior to the event, the Zoo closes to the public at 4 p.m. (all pathways, restaurants, exhibits and attractions will no longer be open.) Doors will re-open at 5 p.m. for the event. Zoo guests planning to attend Boo at the Zoo will need to exit the Zoo and have their event tickets scanned for re-entry starting at 5 p.m.
 

Buying tickets online is the best option as the Zoo is experiencing high call volumes. Tickets do sell out, so buying in advance is recommended.
