This 55-acre arboretum is a great spot to picnic, with picturesque bridges, ponds, and statues dotting the landscape of 6,000 types of trees and bushes. The duck pond, also home to turtles, is a lovely spot for younger children. Check out the fragrance garden with its heady sent of lemon verbena and lavender. There is a small bookstore from which tours are given daily.
