Bayard Cutting Arboretum State Park is a 691-acre (2.80 km2) state park located in the hamlet of Great River, New York, on Long Island. The park includes an arboretum designed by Frederick Law Olmsted for William Bayard Cutting in 1887, as well as a mansion designed by Charles C. Haight.
The house at the heart of the park, Westbrook, is modeled on an English country house. Both the house and property were given to the people of Long Island by Bayard Cutting's widow and daughter "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 park has a nature trail and recreational programs, and there is a food and a gift shop at Westbrook.(Wikipedia)
