Do you have to pay to get in the nature center and how much is it

$2.50 per person or $10 per family

You don't have to pay to walk around but to get into the actual building I think you do but I'm not sure how much it is

According to the website you are supposed to pay $2.50/person or $10/family. We could drive in without paying but we stopped at the building to pay.
