Maybe in the plaza area outside of the main entrance/train station you could put the name of the park into the floor. It could be just different blocks or even engraved, although an engraving might be annoying to walk on.

What I meant by annoying is just the elevation change, as it might be distracting, plus it might not look as good as just different blocks.
