Located at the west end of the Sabine causeway in Port Arthur, the facilities in this state park appear to be operated & maintained by Jefferson County. There are about 15 or so RV sites in a parking lot, all sites are close together. I could not find the price for these sites. Overnight parking appears to be allowed along the perimeter road; sign indicates $10. Could not find a pay station nor a host. There is a rest room, but it's locked with a keypad. Two Porta Potties bear by. Could be a good place for an overnight, but have no more info. Perhaps a future reviewer canaddmoee info.
