Acker Park is a hidden gem that is located on the intersection of Lehigh Avenue and Woodland Avenue in Roselle Park. This park was recently funded and renovated.

It is completely fenced, although the main entrance is kept open during park hours.

I found this virtual tour of Acker Park Playground.
