For a less crowded piece of the Galveston coast, go to a quiet stretch of coast favored by the locals during high season at the end of 8 Mile Road. To get there, take Seawall Blvd west until the seawall ends and it turns into Termini San Luis Pass Rd. Turn left on 8 Mile Rd and drive until you hit the water. Park on the beach, and enjoy.
