Caumsett State Historic Park

Caumsett State Historic Park is a nature preserve on the Lloyd Neck peninsula in New York, covering roughly 1,520 acres (615 hectares) with woodlands, salt marshes, and rocky shoreline along Long Island Sound. Grasslands extend from the former estate grounds down to the water, broken by winding trails and small coves.

Marshall Field III established the estate starting in 1921 and built an English Revival mansion five years later. New York State acquired the property in 1961 and opened it as a public park.

The name derives from a Dutch word describing the flat, brushy landscape early settlers encountered on this peninsula. Today anglers and riders use trails along the coast and through open meadows, while families walk down to beaches facing the Sound.

Several miles of trails wind through varied terrain and suit walkers, cyclists, and riders with proper permits. Beach sections along the water offer opportunities for fishing and diving, with certain zones protected during nesting season.

Over 200 bird species inhabit the park, including rare piping plovers and least terns that nest along the protected shore. The Henry Lloyd Manor House from 1711 presents colonial life exhibitions managed by the local historical society.
