Happy Halloween! The Arboretum invites you to our annual ArBOOretum fall festival. At ArBOOretum all the little ghouls and goblins and their parents come to play, learn, and have an enchanting day enjoying festive activities on the grounds of our nature sanctuary.

This fantastic family event features a Trick-or-Treat Trail where kids learn about different creatures and collect candy while traveling along one of our nature trails.

ArBOOretum filled with a witch’s brew of activities including:
  • Trick or treating
  • Train rides
  • Live owls and reptiles
  • Petting zoo 
  • Pony rides
  • Pumpkin decorating
  • Face painting
  • Food trucks
  • …and more!
Come have a ghostly good time in our SUPER-natural environment.
