The Morton Arboretum covers 1700 Acres. Nice combination of a tree research facility and diverse collections of trees. You won't find this diversity of species in the county forest preserves. Many kid-focused and educational areas. A single-person membership is only $60/yr; for me that's a great value, and I look forward to exploring the Arboretum throughout the year.
