Central Park is huge, and as such has many many things to see and do. There are a number of food vendors around, try the hot nuts, you won't be disappointed. It was winter during my visit and so we went ice skating, it was quite busy and expensive. Apparently there is a free skating rink at the north end of the park but we didn't venture up there. If you really want to see the whole park, either allocate a whole day for walking or hire bicycles because it is truly immense.
