Located in Glen Cove on the famous "Gold Coast" of Long Island's North Shore, this lovely piece of land, at one time an estate, now offers a fine example of the tall moist hardwood forests that used to dominate the area.
The Preserve features four blazed trails that are easy to walk. Approaching from the parking area, the path to the left of the mansion is a direct walk down hill to the beach where one can hike along the shore with views across the Long Island Sound. Trails to the right and back of the mansion are more rugged. Trail maps are available on site.
What is now Welwyn Preserve once belonged to Harold Irving Pratt, son of oil magnate and philanthropist Charles Pratt of the late 1800s. The estate includes a Georgian-style mansion, now used by the Holocaust Memorial and Tolerance Center of Nassau County, and several smaller service buildings.
The Preserve offers an impressive abundance of hardwood trees which are protected and have been allowed to mature. Of particular interests are the tulip trees, also known as yellow poplars. The yellow poplar is a tall, beautiful tree, and is the most naturally occurring on Long Island. In addition, a variety of wildflowers may be enjoyed in April and May. Other trees and shrubs are here, including a stand of Austrian black pines, as the result of extensive landscaping carried out in the earlier parts of the last century. The Pratts contracted the work to members of the Olmsted family, whose famous patriarch, Frederick Law Olmsted, designed Central Park.
