All parts of the Washington Park Arboretum (except the Japanese Garden), are free of charge and open to the public every day from dawn to 8pm.
Seasonal interest at the Arboretum
The Arboretum has 230 acres of landscaped gardens, natural areas, and wetlands, plus a world-class collection of 10,000 trees, shrubs, and other plants—plenty of material for wide-eyed, hands-on learning. All year round you’ll find something of interest along the trails that wind through the park:
Winter at the Arboretum
