Municipalities are allowed to decide whether to keep local municipal parks open or to close them. The following are municipalities in our area where officials have made announcements about whether local parks will remain open or closed.

Princeton – In Princeton, municipal parks are still open. In a message on Planet Princeton’s Facebook page, Councilwoman Eve Niedergang wrote, “Princeton has no inclination at this point to close all the parks; if PPD (Princeton Police) and PHD (Princeton Health Department) think that there is a problem in a particular park, that park will be closed.” Community garden plots in Princeton are closed until at least May 1. All municipal basketball, tennis, and platform tennis courts are closed. All municipal playgrounds and sandboxes are closed, and the use of municipal fields and facilities by all sports organizations is suspended through April 30. Men’s and women’s platform tennis is canceled for the rest of the season.

If you have information we should add to this list, please let us know in comments or via email. Thank you.


  1. Is it possible to get a list of the municipal parks in Princeton still open? Went online and could not easily find anything. The princetonnj.gov website info on parks is “under construction” (& unhelpfully refers to another parks recreation site that only lists sports league news).

  2. How about rosedale park? I live near it, see a flashing sign that says closed But everyday, I see cars and walkers there. Not sure if the sign was put up to keep non locals out. Thank you!

    1. Rosedale seems to be now part of Mercer Meadows(?) and the County closed that. Thought that Rosedale belonged to Hopewell, but…. ?
