Is there public beach access? where do you park for that?

Right now, sure to high water levels, the main public access beach is not accessable. There are a couple day parking area still available.

There are several public beaches there. The first is outside the park entrance, with parking. Several turn-out parking and beach access points inside the park as well (although you will need a pass)

There are small parking areas along the road with a path down to the water. If there is no where to park you can park at the dead end before you turn left into the park.
