A good place to go would be Galveston Island State Park. East Beach is not bad and you can drive on it, but it can get crowded. You have access to the jetty from there though and the fishing can be pretty good. On the west end of the island, there are miles of beach you can access. You can always hit one of the piers or rock groins that are right on the seawall too.
