Like Meadowlark said, the souther you go, the clearer the water (I know, but it sounded like a cool word). My favorite spots are Matagorda and Rockport, but the entire Texas coast offers great redfishing. Up the coast where the water is murkier, you can get closer to the fish. Down the coast where the water is clearer, you can see the bottom better, and see the fish in deeper water better, but it can be harder to get close. Generally, the upper coast has more soft (as in too soft to wade) bottom, and the lower coast has more firm bottom that is suitable to wade. In Matagorda the water is usually pretty stained; in Rockport it is considerably less stained. In Aransas Pass and on down into the Laguna, it is mostly very clear, shallow, and well vegetated. But it's all good. Take some five to eight weight rods to cover all of the wind possibilities, and have a ball. Good luck!
