Hi Scott, the Zoo is open from 10:00 am - 5:00 pm during the summer with the last admission at 4:30 pm (April – September).
The last tickets for the day are sold 30 mibutes before closing...summer hours are closing at 5pm, so the final ticket sales for the day are at 4:30pm.
One half hour before closing time.
3:30 I believe but try to get there earlier because sometimes there's a line
They close the zoo at 4pm. Open 11am. Tickets sold up to 330
I believe it's a half hour before closing time. 430 I think.
