The Zoo invites you to join us for Boo at the Zoo, a merry-not-scary trick-or-treating extravaganza. Wear your best costumes and visit the Zoo on October 22, 23 and October 29 and 30th. Children can visit treat stations throughout the Zoo, make a memory at the Safari Snapshot photo booth and wander throughout the merry-not-scary Hay Maze. Admissions are open from 9:30 a.m. to 4:00 p.m. Zoo grounds close at 5 p.m.
