If you're looking for a beach around the La Porte area, you're not going to find one. There are several signs directing travelers to Sylvan Beach, but don't bother going there unless you just want to look at the ships going down the Houston Ship Channel. There is no beach...
If you are interested in going to the beach, Texas City is only 15 miles south of La Porte, and Galveston is another 12 to 15 from there. My favorite place to go when I'm looking for a beach in the area is San Luis Pass, which is located on the South end of Galveston Island.

Along with dentist facilties, there was also a barbers shop which was needed to enforce the Navy's concerns about hair length. There was also an operating room, sick bay and isolation ward.
