Bayard Cutting Arboretum was donated to the Long Island State Park Region by Mrs. William Bayard Cutting and her daughter, Mrs. Olivia James, in memory of her husband, William Bayard Cutting. The intent of the donation was “to provide an oasis of beauty and quiet for the pleasure, rest and refreshment of those who delight in outdoor beauty; and to bring about a greater appreciation and understanding of the value and importance of informal planting.”

The Arboretum is a passive park, and activities such as biking, picnicking, sports, bathing, and games are not permitted.
