Online reservations for timed tickets are required for all non-member guests. Guests must arrive at their reserved time slot to ensure capacity is not exceeded. Members are not required to make online reservations to visit the Zoo.

Your reserved time slot is your assigned arrival time. Once you arrive within that time frame, you are welcome to enjoy the Zoo until we close at 5:00 p.m.

A portion of each Houston Zoo ticket purchase goes towards protecting animals in the wild.
