The Arnold Arboretum, founded by Harvard University, is the oldest arboretum in North America. Not just a pretty park, the arboretum is grounds for research on evolution, plant pathology and other treesearch (pun shamefully intended). Admire beautiful views of the Boston city skyline from Peters Hill or go for a cycle along the many paths for a perfect spring afternoon.
Every one of the 14,980 individual plants in the Arnold Arboretum living collection is tagged with its species name and other information, making for an educational park experience.
