Tagging a park entrance

I would like to add the access points for the High Line Park in New York City. For those not familiar, this was an old elevated railway recently converted to a park. Since it’s elevated, there are only certain locations where visitors can enter the park. What’s the best way to tag these POIs to make it clear that they are part of the park. “Parking area” doesn’t seem to make much sense.

Aren’t these all highway=steps? Since the High Line is elevated (bridge=yes), it will by default not connect to intersecting streets. So even if there’s a ramp rather than stairs, highway=footway on the connection should be enough.
