Boo at the Zoo brings a spooky twist to Austin Zoo in Austin, Texas. Kids can show off their costumes on a creepy train ride, pick between scary and not-scary haunted-house options, and wander past the zoo animals after dark. Bring flashlights for the evening outing, since the zoo gets a little extra spooky once the sun goes down. It's a fun pick for families who want a Halloween outing with a wild side.
