The Loop Playground in Mountainside NJ (with Photos)

The Loop Playground is another one of those playgrounds that we accidently discovered back in 2019. We were visiting the Trailside Nature Center and as we explored the property and the hiking trails, we stumbled upon the Loop Playground in Mountainside, New Jersey.

We couldn’t help ourselves. We had to stop and play. As it turned out Melanie had visited this Mountainside playground first and blogged about it here in 2014. With our visit we decided to take more pictures, create a video, and expand on what we had to say about this amazing and fun North Jersey playground. Now, we’re updating our Mountainside playground review again in 2022 with those pictures and more to help you see how fun this area can be.
