What Patton said. You can purchase tickets online and show them to the gatekeeper and walk right in.
No need for a reservation
Just walk in bring your ID with you
No reservations needed however if you plan on taking the train ride that the zoo offers it has certain hours
Yeah the zoo never fills up, you can just walk in. If you buy your ticket online before you go you do get to skip the ticket line though.
Just walk in.
