How much just to enter the park?

Per website: Admission is charged to enter regional parks on weekends and holidays only. $1.50 per person (ages 6 and up) $8 maximum charge per vehicle (six to nine occupants) $20 maximum charge per commercial vehicle/school bus There is no fee to enter Boaters Park, nature centers, natural areas, and Deerfield Island Park. At Hollywood North Beach Park, a parking fee is charged instead of the gate entrance fee.

Pretty sure it's free. It's a public park.
