My first times camping out was on the beach, South Padre Island. Mainly we would just camp out under the stars with a tarp shade at times.

But on one trip a friend of mine had a small travel trailer (not fiberglass), too keep the sand out of it we had a bucket of water by the door to wash the sand off our feet. We pulled a lot of people out the the sand with my old '46 Jeep as well. When I took my kids down to see the beach on a Spring Break (later than most of the Texas Breaks), I would not take my C-class RV onto the beach itself (keep from getting it stuck) but we did park near the entrance to the beach as a day camp and then later at a pull off of the major road and also at a nice county park campgound at the south end of the island. We had also gone to Mustang Island and stayed at the State Park there. Camping is behind the dunes from the beach, a short walk to the beach. Be sure to wash the egg off as soon as possible once you get away from the beach area to get the salt spray off of any metal areas as well as the tow vechle. Beach camping is fun but the sand can get all over if not careful, and the salt is in the air and in the sand as well. I grew up in the Gulf Coast some mile from the Gulf but we had a lot of rust on our cars and trucks, etc. One can normally get way from the Spring Break Crowds by keeping away from the Condo and Hotels and South Padre the town. One can drive miles down the beach to get away from the crowds. Drive on the wet sand to keep from getting stuck.
Goose Island State Park, surrounded by the St. Charles and Aransas Bays, is located north of Rockport & near Freeport in Aransas County. Nice area by the Gulf of Mexico. I want to do this one someday.
