Port Aransas is a small town on the north end of Padre Island, just off the coast from Corpus Christi, TX. Padre Island, the longest barrier island in the world, runs along the Texas gulf coast for about 113 miles, from Brownsville near the border with Mexico to north of Corpus Christi. We stayed at the Pioneer RV Resort which is on the beach about 3 miles south of Port Aransas. From the RV park they have a short boardwalk that takes you out onto the sand. In Texas, the beaches are treated as legal roadways so you can drive out onto the sand. Periodically there are access points where you can get back onto the more traditional roadways.
