Do I have to pay if I go by bike to enter to the beach?

No motorcycle allowed

No

You only have to pay to park your car. So if you want to ride your bike or walk on its free. Depending if you live in Bridgeport or not changes the price of the parking. I live in Bridgeport and pay $15 to park for the season.

Nope

I don't have any idea

Is free

No fee/charge to bicycle or walk in. The #1 & #9 GBT buses drop-off/pickup at designated stops at Seaside Park.

No you don't
