Prisma Health Boo in the Zoo is the Greenville Zoo’s signature Halloween event, featuring 20 trick-or-treat stations, character photo opportunities, an extinct species graveyard, Dragon Alley and Alice's Fun House. 

The event also features a free park and ride service provided by Greenlink. Each night, three buses will transport event attendees from County Square (301 University Ridge) to the zoo, running continuously between the two locations. Shuttle service will be available from an hour before the event starts until an hour after the event ends.
