Discovery Saturdays


Make a discovery at the Arboretum and enjoy a unique family experience. Drop by the Stackhouse Education Center on Saturdays, any time between 9:00 am and 1:00 pm, for an interactive exploration of nature. Each week discover a new plant, animal or environmental topic through experiments, stories, games and crafts. Borrow an Arboretum backpack loaded with binoculars, field guides, a magnifying glass and everything else needed for an outdoor Arboretum adventure! No pre-registration is necessary. Adults must be accompanied by a child.
