The park is free, but you need a ticket for the train rides, carousel, and museum. Tickets are $2 each (under 2 are free) or 6 tickets for $10. You can also purchase an all day wristband for $10.
Free
No fee to enter but you buy tickets to ride the train, carousel and enter the museum. Tickets are inexpensive at I think $2 each or several for a discounted price.
