Hi, The entrance Price is 29$ for an adulte and 18$ for a 5 to 12 years old children. But if you planed to visit NYC for few days, it's more interesting to get a New York City Pass for 110$ which allow you to get Access to 6 differents museum or special place.
It is not free and you will have to book tickets in advance in the high season as the queues are really long to get up there. The prices are vary between $32-$38
