Galveston is nice.. it's probably the 2nd best large area to wade/bank fish in Texas. High Island/SLP/West Bay are legendary!
However, PA and CC have so many bank locations you couldn't fish them all in a summer if you tried and I have tried. Every where you go you can fish.. Everywhere just about.. PLUS! The best seafood resties are there, the Galveston area has maybe 3.
CC and PA offer Surf, Jetties, Piers, Cuts, and Islands fishing... Get a Kayak and you are in business! Don't want a Kayak there are boat rentals for $60 a day, J16's. Only downside is the summer crowds especially on Mustang Island!
But if you get tired of that you relocate to SPI a few hours away. SPI is not a fishing destination so the hot spots are never really crowded even in High season.
Unfortunatly the worse place, out side Port Lavaca, ha, is South Padre Island. SPI is a bank fisherman's nightmare. Unless you want to target BIG sharks SPI has limited wading and bank spots that one can easily reach. SPI is a becoming more focused on watersport activites and their beautiful beach life than a fishing hub. Can't blame them, more money!
Another thing I love about Aransas/CC is you can literally jump outta your car and chunk lures all over the place. Driving to the supermarket? Take a 5 min detour and boom you could see tailing reds! Plus Aransas and is like the Bait Stand Capital/Fishing Tackle Shop of Texas where South Padre isn't.
