Central Park is a thousand acres, amidst Manhattan, and indeed is amazing.  
The park here is 200 acres, and also, to me, amazing.  It's a huge part of what makes this area desirable, just as Central Park works in Manhattan.
They have smaller parks dotted around.  The potential money taken up by parks I think pays out manifold in property values around said park.
Waterfront parks are also super nice.  I thought Cincinnati really blew a chance back in the day when they put two stadiums on the waterfront when there was room further inland, not the river front there is .... not what I like.
