One of the best sights along the Seawall in Galveston is the Pleasure Pier. If you have been, and are missing the view, you can check out the surfcam. It will remind you how nice it is to have the opportunity to visit in person.
Located on the East side of Galveston Island, Beachtown is always one of my favorite places to launch a sunset walk on the beach. The homes are beautiful and if you time things right, you might just have the whole beach to yourself.
