North Bay Avenue & Oak Avenue, Toms River, NJ. What a great playground, my sons both had a wonderful time. We spent the day at Blackbeard’s cave http://www.blackbeardscave.com/ ($18 for wristband from 12-5pm on sunday) and then came over here for some more play. It was a full day and the kids want to go back! At Castle Park II there are 2 playgrounds, a pre-school age 2-5 and school-age 5-10. It is a very popular place with tons of kids. There are 2 toddler swings and more bigger swings. Slides, sway-fun (big swaying apparatus, see pic), and lots of castle structures. See the pics for details.
