Is the summer entertainment budget running low but the kids don't go back to school for another month? Looking for something to do with out-of-state guests but don't want to break the bank? Or just looking for an inexpensive way to spend your weekends?

Not a problem. New Jersey has lots of free activities and events to keep adults and children busy year-round.

The Garden State is packed with parks (all state parks have free entry this year), museums and events at no cost. Here are 10 of them.

This is a great time to visit the state's museum as local artists' works are on display. The "New Jersey Arts Annual: Reemergence" highlights the work of visual artists and craftspeople from around the state. This year’s exhibition shows artists from the state taking steps to "reemerge into an altered landscape" following the pandemic. There are 127 works by 95 artists in the exhibit. Here is the complete list of artists included.

The museum also features its "Jaw Dropping World of Sharks" display through January 2023.

If you really love sharks, the museum holds a free sharks lecture on the second Saturday of each month at 2 p.m.

The museum also houses 12,000 other works of art, a collection of more than 2 million prehistoric and historic specimens, 13,000 artifacts that document the state’s history and a Civil War flags gallery showcasing the flags carried by New Jersey soldiers during the war, among others.
