Rockport has a lovely, mile long beach that is perfect for the little ones. The beach has shallow water with sand bars ever so often and the waves are generally not large like you will find on the islands of Mustang and Padre and Galveston. They can play in the sand - build sand castles - enjoy the water. Occasionally there will be jelly fish, but they are common on the islands as well. I must say that the shell picking is not as nice as the island beaches, but there is a harbor, lots of fresh seafood, a small aquarium, tourist shopping, and tons of fishing possibilities and birds of all sorts to see. There is certainly enough in Rockport to make a trip to the beach for the little ones just as enjoyable for their parents. Rockport is about 3 1/2 hour drive from Austin, and there are several routes to drive down there, and historical places to visit along the way. Have fun...we were down there two weeks ago and the kids were already playing in the water!
