Best Swimming Lakes in New Jersey for Families in 2020

New Jersey is known for its outstanding beaches, but it also has some of the best swimming lakes in the Northeast. This summer, if you want a break from the pounding waves, dive into the calm waters of one of these beautiful New Jersey lakes, which have started to reopen for the 2020 swimming season.

Swimming is now allowed at the lakes within New Jersey State Parks, but each park is deciding when and if to open. We have updated this NJ swimming lakes article with current information, but please call ahead as things are changing quickly. Parking lots are generally limited to 50% capacity and visitors are often limited to a two-hour stay to allow others to utilize the parks. The NJ State Parks Facebook page regularly updates which parks have reached capacity so be sure and check there before heading out. 

Note that the lakes' swimming hours are subject to change to due weather and staff changes. Check the NJ Department of Environmental Protection's daily swim schedule for updates.
