Why do I pay a toll before the bridge then another one here?

The state of Florida has 2 toll booths on Pinellas Bayway approaching the park. One costs 75 cents and the other is a 50 cent toll. The $5 per vehicle parking fee at Fort De Soto is collected by Pinellas County.

Patrons can pay the County’s $5 parking fee using either the Flowbird mobile app, pay-by-text, existing parking terminals or annual pass. Please note: If you are using the app or pay-by-text option, there is a $0.35 cent convenience fee for submitting your payment using the app or pay-by-text option. Visa, Mastercard and American Express are accepted.
