No admission ticket is necessary. There is a separate charge for the activities like corn maze and hay ride. You pay only for what you want to do.
I found it to be a little pricey because everything was separate and I spent 70 just for pumpkins not including the activities. Also they don't accept credit. There is a Mac machine though. For instance schaeffer farms which is near flemington charge a flat rate for pumpkins small one price med another and large more.
