This is a city park that is great fun for the little kids. And if you cross Baker street (to the west) the ducks in Riverside Park are fun, although they can be a bit aggressive. (And there's another good cache there).
The cache coordinates will take you to a large tree. From there go straight south to the hedgerow of skinny trees. It should be an easy find, so I won't say more unless you need a hint.
Bring your own pen/pencil.
