All out-of-state residents living in the Rio Grande Valley for the winter will be able to visit the Zoo for the special admission price of $4.50. Residents will need to show proof of out-of-state residency. Identification such as a driver’s license, utility receipt or school ID will suffice. At least one family member must show proof of residency at the gate. In addition to the discount, we’ll also have activities, refreshments, tours and door prizes from 10:00 a.m. to 3:00 p.m.
