Main image

Heckscher State Park is a state-run park on the south shore of Long Island in Suffolk County, New York. The park was created from land donated by August Heckscher in the early 20th century.

The park offers saltwater shoreline on the Great South Bay, wooded trails, open lawns and picnic areas, and shoreline access for fishing and birdwatching. Recreational facilities and waterfront areas make it popular for family outings and local day use.

The park originated when August Heckscher gifted land to New York State to create public parkland; it has since been managed as a state park. Over time the park has been developed with visitor facilities while retaining shoreline and natural areas.

The park sits on the south shore of Long Island in Suffolk County near the communities of Great River and Islip. It is part of Long Island’s coastal park system and is accessible by road from other parts of the island.

  • Founding donation: The park sits on Long Island's south shore and was donated to New York State by philanthropist August Heckscher.
  • Best time to visit: Best visited in summer for beach access and in spring and fall for birdwatching along the bay.
