What is the difference between a passive park and an active park?

As a Supervisor of parks for a municipality, I can answer your question. A "Passive Park" is a public area designated as a park, but does not afford facilities or equipment for exercise or play: i.e a nature park or greenspace. It can have benches or trails, but is not conducive for for any "Active" use, such as sport or play. Just reverse that and you have the definition of an "Active" park.
