The 19-acre property embraces a large, freshwater pond just above Natural Bridges State Beach, as well as adjacent riparian lands. Antonelli was donated to the Land Trust in four parcels between 1982 and 1994. There are trails for public enjoyment and habitat for abundant flora and fauna. The main entrance to the park, which is open from dawn to dusk, is located on Delaware Avenue between Natural Bridges Drive and Shaffer Road.
