Each week a Hoyt Naturalist will be stationed out in the Arboretum Visitors Center to teach about an environmental education theme. Family Forest Days will be accompanied with a self-lead activity to learn with your children as you stroll along the wooded trails. For ages 4 to 12, will run rain or shine.
