With 14 acres of exhibits throughout indoor and outdoor spaces, we have plenty of room for you to enjoy a safe and socially distanced experience. As you prepare for your visit, we want you to be aware of the following new guidelines and safety measures in place. These may be subject to change in the following months. 


Please note that Monday through Thursday all visitors should plan to enter through our East Box Office (stingray building). Both the East and West Box Offices will be open Friday through Sunday.

Additionally, the grill will be open Fridays, Saturdays and Sundays from 11 a.m. - 3 p.m.

Regarding the use of face masks per the CDC: “fully vaccinated people no longer need to wear a mask or physically distance in any setting”. For youth ages 3 to 12 and those who are unvaccinated, the CDC strongly recommends you continue wearing masks while indoors or unable to social distance.
