Thrills, chills, and animals await you at Franklin Park Zoo’s annual Zoo Howl! During this popular Halloween event, children throughout New England are invited to trick-or-treat among the animals at the Zoo. Other haunted happenings include creepy crafts, ghoulish games, costume contests and a haunted maze! Throughout the day, guests can learn about the importance of enrichment as they watch as many of the animals receive pumpkins, generously provided by Whole Foods Market of Jamaica Plain, as enrichment items.
