Are there park benches near the beach? Walking with a cane, being able to sit for a while would be helpful.

There are some

Not sure we go tent camping and fishing there

There is a Trail for Bikes and Walking with occasional benches

There are a few places to sit near the restrooms, and there are several tables with chairs near the concession stand. Picnic tables with benches are closeby in the park which is right off the beach area.

It's not too far, there are many beach you can go, because the park is in the island. Enjoy it.

Yes there is
