The Detroit Zoo’s annual “merry, not-scary” Zoo Boo celebration returns this Halloween season, featuring a festively decorated half-mile trick-or-treat trail through the front of the park. Those who dare can follow a trail of eerie fog and mysterious sounds through a spooky graveyard to the Haunted Reptile House, where witches, mummies, vampires and other monsters have taken up residence for the Halloween season.

Zoo Boo will be held on the evenings of Oct. 17 to 19, Oct. 24 to 26, and Oct. 30 - 31 from 6 p.m. to 8 p.m., rain or shine.

Advance tickets for Zoo Boo can be purchased at Guest Relations and at Window One at the front of the Detroit Zoo or by visiting the Detroit Zoo website www.detroitzoo.org.  Tickets are $6 per person, ages 2 and up. If a date and time slot is not sold out, a limited number of tickets will be available at the gate after 5 p.m. that day for $10 per person.
