The park is located at the western end of Mott Avenue in Bayswater near Far Rockaway and is built on land that once housed the mansion and estate of banker Louis A. Heinsheimer.

The mansion, which by that point had been damaged by fire, was demolished in 1987 prior to the land being given to New York State in 1988; only the conservatory was left standing.

[5] Between 1994 and 1996, the Audubon Society conducted a research and restoration project at Bayswater Point, seeking to engage the public with the land's conservation.

[9] Bayswater Point State Park was established in order to preserve important habitat for migratory birds in Jamaica Bay.

The park also protects habitat for butterflies such as the Delaware skipper, and its beach is used by horseshoe crabs during their annual mating season.
