The park itself & parking lot, including the bathrooms are wheelchair accessible. However the beach entrance does have stairs both up & down to get over the protective dune to get to the beach itself. There is a ramp, but that only gets you halfway up the stairs then there are steps down to get to the beach level.
Yes it is
There is a walkway that leads down to the sand
I know there's a ramp on one side, but I also remember stairs, I'd be surprised if it wasn't accessible, and I wish I could remember so I could say for sure, I'm sorry.
Yes and yes
