Kids can soon Trick or Treat at Busch Gardens! Howl-O-Scream has started at Busch Gardens Tampa, but not everything is scary. Kids will soon be able to Trick or Treat! It will take place on Saturdays and Sundays, October 3 through November 1. There are other kid friendly activities as well. Unlike Howl-O-Scream, Trick or Treating is included with your general admission. You can learn more information here.
