Ketih just about covered everything you need to know.

Podickery and WRCRA are private launches and NOT public access.

FYI, You may have to get to Sandy Point early on popular weekends because they will close the park and the parking lot by the small boat launch.

Oh... and the depth drops off quickly on the point so don't send your wife out there to hang onto the boat.

The Rangers will tell you to not drive on the treadle from the parking lot and to sail out through the marked channel.

You will need beach wheels to make it to the water without much pain and suffering. You will loose your vehicle if you even try to drive on the sand. It's super soft
not to mention the fine when they catch you and the tow out.

Finally, don't speed in the park... they love to use their radar gun!

Take Care
