after you come through High Island Texas the road turns right to run towards the ferry to Galveston.
Just at the turn you will see a sand road to the left. Take it. Underneath the sand you will find the old pavement from the road that washed away 10-12 years ago.
Also just as you approach the ferry to Galveston you will see Rettilon ST (? spelling). This will lead you to the flats a popular beach camping spot. YOu will see lots of campers on the beach. I take my 27 foot class out on it.
Remember you need a $10.00 sticker to be legal.
