Willowwood Arboretum spans 131 acres of cultivated and natural landscapes in Morris County, welcoming visitors daily as part of the county park system. Thoughtfully designed plantings, specimen collections, and gently winding paths invite exploration through seasonal gardens, woodlands, and open lawns. From April through November, visitors can deepen their experience by following a self-guided cell phone tour that shares insights about the gardens and their design as you move through the landscape. Together, the grounds offer a relaxed way to explore horticulture, seasonal change, and quiet moments outdoors.
