If one takes in the entire county park complex, especially across the street from Union County College, yes there is a playground and a restroom building. But if one is just interested in Lenape Park, park area furthest from the college campus; no playground and only a porto-john. Nice little lake in both areas, however.
The answers above are correct. There are playgrounds and restrooms in adjacent Nomahagen as well as Echo Lake parks, but not in Lenape itself.
Nearby, but not inside of.
