Not sure about Credit Cards. It's only $5 per car if you live in Marion Co. If you live outside of Marion Co., it's $6 per car.

The beach itself is a major disappointment. We went once and never again. The water was dirty, there were straw/hay and ants on the beach, and it was tiny. You cannot bring beer. I believe that you can bring a cooler. Head up to Indiana Dunes if you want a nice beach. It is spectacular.

Certainly the building with the birding observation area is accessible. I would think that the trails would be a bit rough but there may be parts that are more conducive to wheelchairs. Call the park for more info.

It only really matters if you plan on driving into the park (if you walk into the park it isn't important). Drivers of Marion county registered cars will pay $5 - otherwise the fee is $6.

It depends on the resident status and whether or not you’re bringing a boat. The most updated pricing is on the Indianapolis Parks website.
