We've spent many winter months around the Corpus Christi, Texas area and visit South Beach frequently. Plenty to do; fishing, sunbathing, bird watching, photography, and on some evenings after dark you can spot deer and coyote come out of the sand dunes to feed on seaweed and fish remains. We prefer to camp at nearby Malequite campground for $5 a night with water, bathrooms and showers. The visitor's center has some supplies.
